[PATCH 1/2] drm/layerscape: Add HDMI support for DCU DRM driver
Some Freescale SoCs, there has an DVI/HDMI controller and a PHY,
attached to one of their display controller unit's LCDC interfaces.
This patch adds a driver for SiI902x. The SiI902x is a HDMI
transmitter It supports resolutions from standard definition
480i/p and 576i/p all the way to high-definition 720p, 1080i,
and 1080p, the highest resolution supported by HDTVs today.

This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.

[PATCH v13 1/6] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

[PATCH v12 1/6] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

[PATCH v12 1/6] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

Re: [PATCH v11 1/5] drm/layerscape: Add Freescale DCU DRM driver
Hi Dave,
I think Freescale DCU DRM driver is ready now, can it land?
I have worked on this driver for about nine month. Daniel Vetter,
Thierry Reding, Mark yao,
Alexander Stein, Paul Bolle, Alison Wang, Stefan Agner reviewed this
pathset. The latest
version v11 has been send out about an week, and no more comments any more.

[PATCH v11 1/5] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

[PATCH v10 1/5] drm/layerscape: Add Freescale DCU DRM driver
From: Jianwei Wang
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA BGRA ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

[PATCH v8 1/4] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) For the current LCD panel, WQVGA "480x272" is supported.
(3) Blending of each pixel using up to 4 source layers
dependent on size of panel.
(4) Each graphic layer can be placed with one pixel resolution
in either axis.
(5) Each graphic layer support RGB565 and RGB888 direct colors
without alpha
channel and BGRA BGRA ARGB1555 direct colors with an
alpha channel and YUV422 format.
(6) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT LCD panel.

[PATCH v6 1/4] drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing Engine (2D-ACE) on the Freescale SoCs. 2D-ACE is a Freescale display controller. 2D-ACE describes the functionality of the module extremely well its name is a value that cannot be used as a token in programming languages. Instead the valid token "DCU" is used to tag the register names and function names. The Display Controller Unit (DCU) module is a system master that fetches graphics stored in internal or external memory and displays them on a TFT LCD panel. A wide range of panel sizes is supported and the timing of the interface signals is highly configurable. Graphics are read directly from memory and then blended in real-time, which allows for dynamic content creation with minimal CPU intervention. The features: (1) Full RGB888 output to TFT LCD panel. (2) For the current LCD panel, WQVGA "480x272" is supported. (3) Blending of each pixel using up to 4 source layers dependent on size of panel. (4) Each graphic layer can be placed with one pixel resolution in either axis. (5) Each graphic layer support RGB565 and RGB888 direct colors without alpha channel and BGRA BGRA ARGB1555 direct colors with an alpha channel and YUV422 format. (6) Each graphic layer support alpha blending with 8-bit resolution. This is a simplified version, only one primary plane, one framebuffer created for fbdev, one crtc, one connector for TFT LCD panel, an encoder.

framebuffer created for fbdev, one crtc, one connector for
TFT LCD panel, an encoder.

Changed in V3:
- Test driver on Vybrid board and add compatible string
- Remove unused functions
- set default crtc for encoder
- replace legacy functions with atomic help functions
- Set the unique name of the DRM device
- Implement irq handle function for vblank interrupt
Changed in v2:
- Add atomic support
- Modify bindings file
- Rename node for compatibility
- Move platform related code out for compatibility

+Device Tree bindings for Freescale DCU DRM Driver
+
+Required properties:
+- compatible: Should be one of
+ * "fsl,ls1021a-dcu".
+ * "fsl,vf610-dcu".
+- reg: Address and length of the register set for dcu.
+- clocks: From common clock binding: handle to dcu clock.
+- clock-names: From common clock binding: Shall be "dcu".
+- display: The phandle to display node.
+
+Required properties:
+- bits-per-pixel: <16> for RGB565,
+ <24> for RGB888,
+ <32> for RGB.
+
+Required timing node for dispplay sub-node:
+- display-timings: Refer to binding doc display-timing.txt for details.
+
+Examples:
+dcu: dcu@2ce {
+ compatible = "fsl,ls1021a-dcu";
+ reg = <0x0 0x2ce 0x0 0x1>;
