The goal is to avoid as much as possible extra versions. Also, as I said before in a response to "[PATCH v14 09/10] ARM: dts: mbimx51sd: Add display support.", the LCD regulator was inverted, it worked while inverted because of a bug which is now fixed by: "imx-drm: parallel-display: Fix DPMS default state."

[PATCH] imx-drm: parallel-display: Fix DPMS default state.
If connector->dpms is left untouched, it defaults to DRM_MODE_DPMS_ON (0). As a result, drm_helper_connector_dpms will exit when it will be asked to set the state to DRM_MODE_DPMS_ON, because it is already set. That issue prevented displays from turning on at boot.

This is wrong, I'll fix it in the next serie.
What it really does is to make regulator-fixed think that the gpio is
active low, the bindings documentation(fixed-regulator.txt) says:
> - enable-active-high: Polarity of GPIO is Active high
> If this property is missing, the default assumed is Active low.
Then regulator-boot-on will make it think that the regulator is already
on and so the regulator will be disabled.
From the bindings documentation (regulator.txt):
> regulator-boot-on: bootloader/firmware enabled regulator
Which result at the lcd regulator being physically powered on at boot.
I didn't see that because powering it on at boot is what I want.
How can I do that beside doing it in userspace by issuing the following
commands:
echo 4 > /sys/devices/display-subsystem/graphics/fb0/blank
echo 0 > /sys/devices/display-subsystem/graphics/fb0/blank

[PATCH v14 09/10] ARM: dts: mbimx51sd: Add display support.
The CMO-QVGA, DVI-SVGA and DVI-VGA are added.
Signed-off-by: Denis Carikli
---
ChangeLog v13->v14:
- None
ChangeLog v10->v13:
- Rebased
- Removed enable-active-high in reg_lcd_3v3: its GPIO
already has the GPIO_ACTIVE_HIGH flag.
Without this removal, the display was off at boot
and powering it off and on was necessary to get an
image on it after the boot.
ChangeLog v10->v11:
- Now uses the drm-panel instead of the display-timings.
This is to get regulator support, which is lacking in
the imx-drm driver when using the display-timings.
ChangeLog v9->v10:
- Rebased
- Now enables the cmo-qvga regulator at boot.
ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- updated pixelclk-active after the following patch:
"imx-drm: Match ipu_di_signal_cfg's clk_pol with its description."
ChangeLog v7->v8:
- Rebased the patch: added the now required imx-drm node.
- Adapted the svga clock-frequency value in order to still
be able to display an image after the following commit:
"imx-drm: ipu-v3: more inteligent DI clock selection"
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Since the pingrp headers were removed, the references
to it where replaced by the actual pins.
- Added the targets to arch/arm/boot/dts/Makefile
ChangeLog v5->v6:
- Reordered the Cc list.
ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.
ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51
boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
might be annoyed by the receiving of that patch which is unrelated to their
subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

[PATCH v14 07/10] imx-drm: Use drm_display_mode timings flags.
The previous hardware behaviour was kept if the
flags are not set.
Signed-off-by: Denis Carikli
---
ChangeLog v13->v14:
- Rebased
ChangeLog v12->v13:
- This patch doesn't need the DRM_MODE_FLAG_POL_*_PRESERVE flags anymore.
- code cleanup to improve readability:
- ENABLE_POL_PRESERVE is now gone
- Less modifications in ipu_di_init_sync_panel
- more readable modifications in int ipu_crtc_mode_set
ChangeLog v11->v12:
- Rebased: It now uses the following new flags defines names:
CLK_POL, ENABLE_POL
- The inversions in ipuv3-crtc.c are now fixed.
- ipuv3-crtc.c was still using mode->private_flags
from the previous versions of this patchset, that's now fixed.
ChangeLog v10->v11:
- This patch was splitted-out and adapted from:
"Prepare imx-drm for extra display-timings retrival."
- The display-timings dt specific part was removed.
- The flags names were changed to use the DRM ones from:
"drm: drm_display_mode: add signal polarity flags"

[PATCH v14 05/10] ARM: dts: imx5*, imx6*: correct display-timings nodes.
The imx-drm driver can't use the de-active and pixelclk-active display-timings properties yet. Instead the data-enable and the pixel data clock polarity are hardcoded in the imx-drm driver. So theses properties are now set to keep the same behaviour when imx-drm will start using them.

[PATCH v14 06/10] drm: drm_display_mode: add signal polarity flags
We need a way to pass signal polarity informations
between DRM panels, and the display drivers.
To do that, a pol_flags field was added to drm_display_mode.
Signed-off-by: Denis Carikli
---
ChangeLog v13->v14:
- Fixed DRM_MODE_FLAG_POL_DE_HIGH's description.
ChangeLog v12->v13:
- Added Docbook documentation for pol_flags the struct field.
- Removed the _PRESERVE defines: it was used by patches
against the imx_drm driver. Now theses patches have been
adapted not to require that defines.
ChangeLog v11->v12:
- Rebased: This patch now applies against drm_modes.h
- Rebased: It now uses the new DRM_MODE_FLAG_POL_DE flags defines names
ChangeLog v10->v11:
- Since the imx-drm won't be able to retrive its regulators
from the device tree when using display-timings nodes,
and that I was told that the drm simple-panel driver
already supported that, I then, instead, added what was
lacking to make the eukrea displays work with the
drm-simple-panel driver.
That required a way to get back the display polarity
informations from the imx-drm driver without affecting
userspace.

[PATCH v13 07/10] imx-drm: Use drm_display_mode timings flags.
The previous hardware behaviour was kept if the
flags are not set.
Signed-off-by: Denis Carikli
---
ChangeLog v12->v13:
- This patch doesn't need the DRM_MODE_FLAG_POL_*_PRESERVE flags anymore.
- code cleanup to improve readability:
- ENABLE_POL_PRESERVE is now gone
- Less modifications in ipu_di_init_sync_panel
- more readable modifications in int ipu_crtc_mode_set
ChangeLog v11->v12:
- Rebased: It now uses the following new flags defines names:
CLK_POL, ENABLE_POL
- The inversions in ipuv3-crtc.c are now fixed.
- ipuv3-crtc.c was still using mode->private_flags
from the previous versions of this patchset, that's now fixed.
ChangeLog v10->v11:
- This patch was splitted-out and adapted from:
"Prepare imx-drm for extra display-timings retrival."
- The display-timings dt specific part was removed.
- The flags names were changed to use the DRM ones from:
"drm: drm_display_mode: add signal polarity flags"

Signed-off-by: Denis Carikli
---
ChangeLog v10->v13:
- Rebased
- Removed enable-active-high in reg_lcd_3v3: its GPIO
already has the GPIO_ACTIVE_HIGH flag.
Without this removal, the display was off at boot
and powering it off and on was necessary to get an
image on it after the boot.
ChangeLog v10->v11:
- Now uses the drm-panel instead of the display-timings.
This is to get regulator support, which is lacking in
the imx-drm driver when using the display-timings.
ChangeLog v9->v10:
- Rebased
- Now enables the cmo-qvga regulator at boot.
ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- updated pixelclk-active after the following patch:
"imx-drm: Match ipu_di_signal_cfg's clk_pol with its description."
ChangeLog v7->v8:
- Rebased the patch: added the now required imx-drm node.
- Adapted the svga clock-frequency value in order to still
be able to display an image after the following commit:
"imx-drm: ipu-v3: more inteligent DI clock selection"
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Since the pingrp headers were removed, the references
to it where replaced by the actual pins.
- Added the targets to arch/arm/boot/dts/Makefile
ChangeLog v5->v6:
- Reordered the Cc list.
ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.
ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51
boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
might be annoyed by the receiving of that patch which is unrelated to their
subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

[PATCH v13 05/10] ARM: dts: imx5*, imx6*: correct display-timings nodes.
The imx-drm driver can't use the de-active and pixelclk-active display-timings properties yet. Instead the data-enable and the pixel data clock polarity are hardcoded in the imx-drm driver. So theses properties are now set to keep the same behaviour when imx-drm will start using them.

[PATCH v13 04/10] imx-drm: use defines for clock polarity settings
Signed-off-by: Denis Carikli
---
ChangeLog 12->v13:
- No changes
ChangeLog 11->v12:
- Improved the define names to match the hardware:
ENABLE_POL is not a clock signal but instead an enable signal.
ChangeLog v9->v10:
- New patch which was splitted out from:
"staging: imx-drm: Use de-active and pixelclk-active display-timings.".
- Fixes many issues in "staging: imx-drm: Use de-active and pixelclk-active
display-timings.":
- More clear meaning of the polarity settings.
- The SET_CLK_POL and SET_DE_POL masks are not
needed anymore.

Hi Denis,
Hi,

What is the purpose of DRM_MODE_FLAG_POL_PIXDATA_PRESERVE?
If 'preserve' means 'ignore' we can set to zero negedge and posedge bits
instead of adding new bit. If it is something different please describe it.
Yes, it meant 'ignore'.
The goal was to be able to have a way to keep the old behavior while
still being able to set the flags.
So, with the imx-drm driver, if none of the DRM_MODE_FLAG_POL_PIXDATA
were set(that is POSEDGE, NEGEDGE, PRESERVE), then in ipuv3-crtc.c, it
went using the old flags settings that were previously hardcoded.
The same applied for DRM_MODE_FLAG_POL_DE.
The patch using theses flags is the 08/12 of this same serie.
struct drm_display_mode {
[..]
+ unsigned int pol_flags;
Adding field and macros description to the DocBook would be nice.
So I will have to describe it in the "Connector Helper Operations"
section of drm.tmpl, right before the mode_valid synopsis ?
Denis.

[PATCH v12][ 08/12] imx-drm: Use drm_display_mode timings flags.
The previous hardware behaviour was kept if the
flags are not set.
Signed-off-by: Denis Carikli
---
ChangeLog v11->v12:
- Rebased: It now uses the following new flags defines names:
CLK_POL, ENABLE_POL
- The inversions in ipuv3-crtc.c are now fixed.
- ipuv3-crtc.c was still using mode->private_flags
from the previous versions of this patchset, that's now fixed.
ChangeLog v10->v11:
- This patch was splitted-out and adapted from:
"Prepare imx-drm for extra display-timings retrival."
- The display-timings dt specific part was removed.
- The flags names were changed to use the DRM ones from:
"drm: drm_display_mode: add signal polarity flags"

[PATCH v12][ 10/12] ARM: dts: mbimx51sd: Add display support.
The CMO-QVGA, DVI-SVGA and DVI-VGA are added.
Signed-off-by: Denis Carikli
---
ChangeLog v10->v11:
- Now uses the drm-panel instead of the display-timings.
This is to get regulator support, which is lacking in
the imx-drm driver when using the display-timings.
ChangeLog v9->v10:
- Rebased
- Now enables the cmo-qvga regulator at boot.
ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- updated pixelclk-active after the following patch:
"imx-drm: Match ipu_di_signal_cfg's clk_pol with its description."
ChangeLog v7->v8:
- Rebased the patch: added the now required imx-drm node.
- Adapted the svga clock-frequency value in order to still
be able to display an image after the following commit:
"imx-drm: ipu-v3: more inteligent DI clock selection"
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Since the pingrp headers were removed, the references
to it where replaced by the actual pins.
- Added the targets to arch/arm/boot/dts/Makefile
ChangeLog v5->v6:
- Reordered the Cc list.
ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.
ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51
boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
might be annoyed by the receiving of that patch which is unrelated to their
subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

[PATCH v12][ 07/12] drm: drm_display_mode: add signal polarity flags
We need a way to pass signal polarity informations
between DRM panels, and the display drivers.
To do that, a pol_flags field was added to drm_display_mode.
Signed-off-by: Denis Carikli
---
ChangeLog v11->v12:
- Rebased: This patch now applies against drm_modes.h
- Rebased: It now uses the new DRM_MODE_FLAG_POL_DE flags defines names
ChangeLog v10->v11:
- Since the imx-drm won't be able to retrive its regulators
from the device tree when using display-timings nodes,
and that I was told that the drm simple-panel driver
already supported that, I then, instead, added what was
lacking to make the eukrea displays work with the
drm-simple-panel driver.
That required a way to get back the display polarity
informations from the imx-drm driver without affecting
userspace.

[PATCH v12][ 06/12] ARM: dts: imx5*, imx6*: correct display-timings nodes.
The imx-drm driver can't use the de-active and
pixelclk-active display-timings properties yet.
Instead the data-enable and the pixel data clock
polarity are hardcoded in the imx-drm driver.
So theses properties are now set to keep
the same behaviour when imx-drm will start
using them.
Signed-off-by: Denis Carikli

ChangeLog v9->v10:
- New patch that was splitted out of:
"staging imx-drm: Use de-active and pixelclk-active
display-timings."

[PATCH v12][ 05/12] imx-drm: use defines for clock polarity settings
Signed-off-by: Denis Carikli
---
ChangeLog 11->v12:
- Improved the define names to match the hardware:
ENABLE_POL is not a clock signal but instead an enable signal.
ChangeLog v9->v10:
- New patch which was splitted out from:
"staging: imx-drm: Use de-active and pixelclk-active display-timings.".
- Fixes many issues in "staging: imx-drm: Use de-active and pixelclk-active
display-timings.":
- More clear meaning of the polarity settings.
- The SET_CLK_POL and SET_DE_POL masks are not
needed anymore.

[PATCH 10/12] ARM: dts: mbimx51sd: Add display support.
The CMO-QVGA, DVI-SVGA and DVI-VGA are added.
Signed-off-by: Denis Carikli
---
ChangeLog v10->v11:
- Now uses the drm-panel instead of the display-timings.
This is to get regulator support, which is lacking in
the imx-drm driver when using the display-timings.
ChangeLog v9->v10:
- Rebased
- Now enables the cmo-qvga regulator at boot.
ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- updated pixelclk-active after the following patch:
"imx-drm: Match ipu_di_signal_cfg's clk_pol with its description."
ChangeLog v7->v8:
- Rebased the patch: added the now required imx-drm node.
- Adapted the svga clock-frequency value in order to still
be able to display an image after the following commit:
"imx-drm: ipu-v3: more inteligent DI clock selection"
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Since the pingrp headers were removed, the references
to it where replaced by the actual pins.
- Added the targets to arch/arm/boot/dts/Makefile
ChangeLog v5->v6:
- Reordered the Cc list.
ChangeLog v3->v5:
- Updated to new GPIO defines.
- Updated to new licenses checkpatch requirements.
- one whitespace cleanup.
ChangeLog v2->v3:
- Splitted out from the patch that added support for the cpuimx51/mbimxsd51
boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
might be annoyed by the receiving of that patch which is unrelated to their
subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

[PATCH v11][ 06/12] ARM: dts: imx5*, imx6*: correct display-timings nodes.
The imx-drm driver can't use the de-active and
pixelclk-active display-timings properties yet.
Instead the data-enable and the pixel data clock
polarity are hardcoded in the imx-drm driver.
So theses properties are now set to keep
the same behaviour when imx-drm will start
using them.
Signed-off-by: Denis Carikli
---
ChangeLog v9->v10:
- New patch that was splitted out of:
"staging imx-drm: Use de-active and pixelclk-active
display-timings."

[PATCH v11][ 05/12] imx-drm: use defines for clock polarity settings
Signed-off-by: Denis Carikli
---
ChangeLog v9->v10:
- New patch which was splitted out from:
"staging: imx-drm: Use de-active and pixelclk-active display-timings.".
- Fixes many issues in "staging: imx-drm: Use de-active and pixelclk-active
display-timings.":
- More clear meaning of the polarity settings.
- The SET_CLK_POL and SET_DE_POL masks are not
needed anymore.

[PATCH 07/12] drm: drm_display_mode: add signal polarity flags
We need a way to pass signal polarity informations
between DRM panels, and the display drivers.
To do that, a pol_flags field was added to drm_display_mode.
Signed-off-by: Denis Carikli
---
ChangeLog v10->v11:
- Since the imx-drm won't be able to retrive its regulators
from the device tree when using display-timings nodes,
and that I was told that the drm simple-panel driver
already supported that, I then, instead, added what was
lacking to make the eukrea displays work with the
drm-simple-panel driver.
That required a way to get back the display polarity
informations from the imx-drm driver without affecting
userspace.

[PATCH v10][ 06/10] ARM: dts: imx5*, imx6*: correct display-timings nodes.
The imx-drm driver can't use the de-active and
pixelclk-active display-timings properties yet.
Instead the data-enable and the pixel data clock
polarity are hardcoded in the imx-drm driver.
So theses properties are now set to keep
the same behaviour when imx-drm will start
using them.

ChangeLog v7->v8:
- Rebased the patch: added the now required imx-drm node.
- Adapted the svga clock-frequency value in order to still
be able to display an image after the following commit:
"imx-drm: ipu-v3: more inteligent DI clock selection"
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Since the pingrp headers were removed, the references
to it where replaced by the actual pins.
- Added the targets to arch/arm/boot/dts/Makefile
ChangeLog v5->v6:
- Reordered the Cc list.
ChangeLog v3->v5:
- Updated to new GPIO defines.

- Splitted out from the patch that added support for the cpuimx51/mbimxsd51
boards.
- This patch now only adds display support.
- Added some interested people in the Cc list, and removed some people that
might be annoyed by the receiving of that patch which is unrelated to their
subsystem.
- rebased and reworked the dts displays addition.
- Also rebased and reworked the fsl,pins usage.

[PATCH v9][ 4/8] imx-drm: Match ipu_di_signal_cfg's clk_pol with its description.
According to the datasheet, setting the di0_polarity_disp_clk field in the GENERAL di register sets the output clock polarity to active high.

[PATCH v9][ 5/8] staging: imx-drm: Use de-active and pixelclk-active display-timings.
If de-active and/or pixelclk-active properties were set in the
display-timings DT node, they were not used.
Instead the data-enable and the pixel data clock polarity
were hardcoded.
The dts were updated to keep the former behaviour.
Signed-off-by: Denis Carikli
---
ChangeLog v8->v9:
- Removed the Cc. They are now set in git-send-email directly.
- Rebased on top of the following patch:
"imx-drm: Match ipu_di_signal_cfg's clk_pol with its description."
- Updated the current dts that were using the ipuv3 accordingly,
to keep the same hardware settings.
- In the display-timing.txt documentation, the pixelclk-active
and de-active optional properties have an "ignored" state
when the property is not set.
In this new version, the respective bits in the
display interface's general register are not touched if the
dt properties are not set.
ChangeLog v7->v8:
- Changed one Cc
ChangeLog v6->v7:
- Shrinked even more the Cc list.
- Rebased the patch
- val is now initialized in imx_pd_connector_get_modes
ChangeLog v5->v6:
- Remove people not concerned by this patch from the Cc list.
- Removed wrong coments from the code.
- Corrected the code style of the "if (!!val)"
ChangeLog v3->v4:
- The old patch was named "staging: imx-drm: ipuv3-crtc: don't harcode some
mode".
- Reworked the patch entierly: we now takes the mode flags from the device tree.
ChangeLog v2->v3:
- Added some interested people in the Cc list.
- Ajusted the flags to match the changes in "drm: Add the lacking
DRM_MODE_FLAG_* for matching the DISPLAY_FLAGS_*"

[PATCHv8][ 4/7] staging: imx-drm: Use de-active and pixelclk-active display-timings.
If de-active and/or pixelclk-active properties were set in the
display-timings DT node, they were not used.
Instead the data-enable and the pixel data clock polarity
were hardcoded.
This change is needed for making the eukrea-cpuimx51
QVGA display work.

The "status = " here should probably be in the board DTS, not in the LCD DTS.
The display is optional on the baseboard of the cpuimx51.
So my idea was to activate the display only for the configurations where
it's used.

The current BGR666 is not consistent with the other color mapings like BGR24.

- the lcd-supply is now called display-supply (not all display are LCD).
- The code and documentation was updated accordingly.
- regulator_is_enabled now guard the regulator enables/disables because
regulator_disable does not check the regulator state.

[PATCHv5][ 4/8] staging: imx-drm: Use de-active and pixelclk-active display-timings.
If de-active and/or pixelclk-active properties were set in the
display-timings DT node, they were not used.
Instead the data-enable and the pixel data clock polarity
were hardcoded.
This change is needed for making the eukrea-cpuimx51

[PATCHv4][ 2/7] staging: imx-drm: Use de-active and pixelclk-active display-timings.
If de-active and/or pixelclk-active properties were set in the
display-timings DT node, they were not used.
Instead the data-enable and the pixel data clock polarity
were hardcoded.
This change is needed for making the eukrea-cpuimx51
QVGA display work.

ChangeLog v3->v4:
- The old patch was named "staging: imx-drm: ipuv3-crtc: don't harcode some
mode".
- Reworked the patch entierly: we now takes the mode flags from the device tree.
ChangeLog v2->v3:
- Added some interested people in the Cc list.
- Ajusted the flags to match the changes in "drm: Add the lacking
DRM_MODE_FLAG_* for matching the DISPLAY_FLAGS_*"

ChangeLog v2->v3:
- Added some interested people in the Cc list.
- the lcd-supply is now called display-supply (not all display are LCD).
- The code and documentation was updated accordingly.
- regulator_is_enabled now guard the regulator enables/disables because
regulator_disable does not check the regulator state.
