 Hello,
 
 The OMAP3 ISP driver was the only user of the OMAP IOVMM API. Now that
 is has been ported to the DMA API, remove the unused virtual memory
 manager.
 
 The removal is split in three patches to ease upstream merge. The
 first patch removes the omap-iovmm driver, the second patch removes
 setting of now unused platform data fields from arch code, and the
 last patch cleans up the platform data structure.

Thanks for the revised series, it looks good. I have also tested the
series on OMAP3, OMAP4 and OMAP5.

For the changes in the entire series,
Acked-by: Suman Anna s-a...@ti.com
   
   Thank you.
   
 I'd like to get at least the first patch merged in v3.17. To avoid
 splitting the series across three kernel versions, it would be nice to
 also merge at least the second patch for v3.17. If there's no risk of
 conflict everything could be merged in one go through the ARM SoC
 tree. Otherwise a stable branch with patch 1/3 will be needed to base
 the arch change on.
 
 Joerg, Tony, how would you like to proceed ?
   
   The v3.17 merge window is getting close, it's probably too late to merge
   patch 2/3. Joerg, could you please take 1/3 in your tree for v3.17 ? 2/3
   and 3/3 would then get in v3.18. Tony, how would you like to proceed for
   those ?
 
  How about Joerg maybe do an immutable branch against v3.16-rc1
  with just these three patches and merge it into your tree?
  
  That way I too can merge the minimal branch in if there are conflics.
  If that works for Joerg, then for arch/arm/*omap* changes:
  
  Acked-by: Tony Lindgren t...@atomide.com
 
 I've created an immutable branch (or, rather, immutable until the changes 
 reach mainline, at which point I will remove the branch) on top of v3.16-rc1 
 with just the three patches from this series. You can find it at.
 
   git://linuxtv.org/pinchartl/media.git omap/iommu
 
 Tony, is there still time to get this (and especially patch 2/3, which 
 touches 
 arch/ code) in v3.17 ?

Yes as long as Joerg is OK to merge that branch in :)

Regards,

Tony

Hmm maybe double check your're booting device tree based kernel
instead of legacy machine ID based kernel? The legacy booting should
still work just fine and no changes has been made to it, but it will
get removed shortly.
  
   I downloaded the version from the test results and it did boot.
 
  OK that's good to hear.
 
   These are combining the uImage and dtb. How do you accomplish this?
 
  You need to make sure you have the appended DTB support enabled like
  we do in omap2plus_defconfig:
 
  CONFIG_ARM_APPENDED_DTB=y
  CONFIG_ARM_ATAG_DTB_COMPAT=y
  CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER=y
 
  Then just cat zImage board.dtb  /tmp/zImage-dtba and run
  mkimage to convert it to a uImage:
 
  $ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
-n Linux -d /tmp/zImage-dtba /tmp/uImage
 
 
  I actually discovered this and got LCD video working. Now USB host is
  not working. The only thing that registers is the OHCI/EHCI hosts.
 
  root@som3517:~# lsusb
  Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
 
  Not sure what the problem is. The USB devices that are plugged in are
  powered but never detected.
 
  Any hints?
 
 So I got the USB host to work on boot with additional entries in the 
 devicetree.
 Documentation/devicetree/bindings/omap-usb-host.txt
 
 Though the devices work if plugged in at boot, any time a device is
 hotplugged then
 the device is not detected. It is powered very briefly and then off
 without any kernel messages.
 
 So hints from this point would be good.

Sorry no idea on that, maybe send a separate email about that with
the USB and PHY people in Cc.

Tony

Re: [PATCH V2 1/2] ARM: OMAP2+: DMA: remove requirement of irq for platform-dma driver

2014-07-22 Thread Tony Lindgren
* Sricharan R r.sricha...@ti.com [140612 04:48]:
 From: Nishanth Menon n...@ti.com
 
 we have currently 2 DMA drivers that try to co-exist.
 drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
 aware and uses arch/arm/plat-omap/dma.c instance created by
 arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).
 
 Currently both try to register interrupts and mach-omap2/plat-omap dma.c
 attempts to use the IRQ number registered by hwmod to register it's own
 interrupt handler.
 
 Now, there is no reasonable way of static allocating DMA irq in GIC
 SPI when we use crossbar. However, since the dma_chan structure is
 freed as a result of IRQ not being present due to devm allocation,
 maintaining information of channel by platform code fails at a later
 point in time when that region of memory is reused.
 
 So, if hwmod does not indicate an IRQ number, then, assume that
 dma-engine will take care of the interrupt handling.

Looks OK to me, applying both into omap-for-v3.17/soc thanks.

Regards,

Tony

 Lining them up with TABs would make them easier to read.

 What is this documenting?  Isn't documentation meant to make things
 clearer?  Now I'm just really confused - by the documentation.

It is documenting the bitfields in VBUS_MNGMNT_SEL1 register. I've 
hopefully made it a bit clearer by adding the following comment and
slightly adjusting the descriptions a little.

/*
 * For all fields in USB2_VBUS_MNGMNT_SEL1

Apart from that it's a standard way to describe bitfields. You can find
some examples in cx231xx-pcb-cfg.h, bnx2x_link.h and cx231xx-avcore.c

  Why are these being abstracted?
  
  Just use {read,write}l_relaxed() directly.
 
 Ok, unabstracted in v3

no, no... all other glues add their own local helpers for register

this sort of function and get very low overhead tracing of every

 They are just bit setting macros, I've converted them over to use BIT macro

 I've asked ST how this value was derirved and why. It came from validation. 
 The docs don't mention that it is necessary, and removing it
 seems to have no ill effects. So I've removed this udelay in v3.

make sure to test with many, many iterations just to make sure.

look at the child's dr-mode property instead of adding your own.

   + }
  
  I'm confused.  What is this doing?  Isn't this the DWC3 driver, which
  already had a platform device structure associated to it?  Perhaps a
  small ASCII diagram describing the layers might be useful.
 
 Your right, this was wrong. It was some legacy code which is
 unnecessary and I've removed this in v3.

if you're going for DT, why don't you create the parent and the child
from DT as omap/exynos/qcom are doing ?

   + dma_set_coherent_mask(dwc3-dev, dev-coherent_dma_mask);
   +

   + dwc3-dev.dma_mask = pdev-dev.dma_mask;
   + dwc3-dev.dma_parms = pdev-dev.dma_parms;

stick to DT device creation. Look into dwc3-omap.c

[PATCH] pinctrl: dra: dt-bindings: Fix pull enable/disable

2014-07-22 Thread Nishanth Menon
The DRA74/72 control module pins have a weak pull up and pull down.
This is configured by bit offset 17. if BIT(17) is 1, a pull up is
selected, else a pull down is selected.

However, this pull resisstor is applied based on BIT(16) -
PULLUDENABLE - if BIT(18) is *0*, then pull as defined in BIT(17) is
applied, else no weak pulls are applied. We defined this in reverse.

Reference: Table 18-5 (Description of the pad configuration register
bits) in Technical Reference Manual Revision (DRA74x revision Q:
SPRUHI2Q Revised June 2014 and DRA72x revision F: SPRUHP2F - Revised
June 2014)

Fixes: 6e58b8f1daaf1a (ARM: dts: DRA7: Add the dts files for dra7 SoC and 
dra7-evm board)
Signed-off-by: Nishanth Menon n...@ti.com
---
Patch based on v3.16-rc5 tag

1: dra72x-evm:  Boot ok: http://slexy.org/raw/s20I6QXQa (needs MMC filesystem 
that current dts does not have.
- Fails in plain Vanilla 3.16-rc5 kernel due to missing patch to handle 
USB IP instance delta (between dra72x and dra74x) appropriately.
- Tested with fixes needed: https://patchwork.kernel.org/patch/4565431/ 
and https://patchwork.kernel.org/patch/4565461/

2: dra7xx-evm:  Boot PASS: http://slexy.org/raw/s21c6X2wOd

Equivalent testing on 3.14 based product kernel:
 dra72x-evm:  Boot PASS: http://slexy.org/raw/s21yIgttJw
 dra7xx-evm:  Boot PASS: http://slexy.org/raw/s20w7OZaJJ

It is obvious that current users of padconf have'nt had trouble with
the wrong definitions. I think I might have been the first to discover
this as emmc on beagleboard-X15 (an upcoming platform) exposed this problem.

Felipe,
Thanks.

Tony,

If you could consider this for the rc cycle it might be great(as well
as for stable). The pull direction error can cause all kinds of
Pull-down Vs Pull-Up contention with severe risk for certain IP
reliability.

 +Texas Instruments Reset Controller

 +Please also refer to reset.txt in this directory for common reset
 +controller binding usage.
 +
 +Specifying the reset entries for the IP module
 +==
 +Parent module:
 +This is the module node that contains the reset registers and bits.
 +
 +example:
 + prcm_resets: resets {
 + compatible = ti,dra7-resets;
 + #reset-cells = 1;
 + };
 +
 +Required parent properties:
 +- compatible : Should be one of,

 + ti,omap5-prm for OMAP5 PRM instances
 + ti,dra7-prm for DRA7xx PRM instances
 + ti,am4-prcm for AM43xx PRCM instances
 + ti,am3-prcm for AM33xx PRCM instances

I am not sure if this belongs to the reset driver bindings, as the PRM
and CM nodes are defined at the SoC level. This document should only be
describing the reset nodes bindings.

Also, please list all the required node properties first, before you can
give an example.

 +
 +Required child reset property:
 +- compatible : Should be
 + resets for All TI SoCs

There is no compatible child property. This should have been the name
of the node, right? Also, please list all the properties required under
this node like #address-cells, #reset-cells etc.

 +
 +example:
 + prm: prm@4ae06000 {
 + compatible = ti,omap5-prm;
 + reg = 0x4ae06000 0x3000;
 +
 + prm_resets: resets {
 + #address-cells = 1;
 + #size-cells = 1;

This is wrong. You haven't corrected this from v2. The reg field is used
to give the offsets for control register and status register, and does
not use any size fields.

 + #reset-cells = 1;
 + };
 + };
 +
 +
 +Reset node declaration
 +==
 +The reset node is declared in a parent child relationship.  The main parent
 +is the PRCM module which contains the base address.  The first child within
 +the reset parent declares the target modules reset name.  This is followed by
 +the control and status offsets.

This is not clear. This is the case with each child node, which is
describing a particular reset domain, and then the individual resets
themselves are defined as child nodes of this reset domain child node.

 +
 +Within the first reset child node is a secondary child node which declares 
 the
 +reset signal of interest.  Under this node the control and status bits
 +are declared.  These bits declare the bit mask for the target reset.
 +
 +
 +Required properties:
 +reg - This is the register offset from the PRCM parent.
 + This must be declared as:
 +
 + reg = control register offset,
 +   status register offset;
 +
 +control-bit - This is the bit within the register which controls the reset
 + of the target module.  This is declared as a bit mask for the register.
 +status-bit - This is the bit within the register which contains the status of
 + the reset of the target module.
 + This is declared as a bit mask for the register.
 +
 +example:
 +prm_resets {
 + dsp_rstctrl {
 + reg = 0x1c00,
 +   0x1c04;

I guess both these entries can be defined in one line.

 +
 + dsp_reset: dsp_reset {
 + control-bit = 0x01;
 + status-bit = 0x01;
 + };
 + };
 +};
 +
 +
 +
 +Client Node Declaration
 +==
 +This is the consumer of the parent node to declare what resets this
 +particular module is interested in.
 +
 +example:
 + src: src@55082000 {
 + resets = reset_src phandle;
 + reset-names = reset_name;
 + };
 +
 +Required Properties:
 +reset_src - This is the parent DT entry for the reset controller
 +phandle - This is the phandle of the specific reset to be used by the clien

There's no IVA on AM4372. Looking at the offset, it looks like you were
defining this for the WkupM3, in which case you got the initial node
name wrong. The PER rstctrl has the reset management for PRU-ICSS, so
you also need to correct the icss_rstctrl accordingly.

 Can you take this patch. I have submitted logs also.

Thanks, queued for 3.17.  And thanks for running rtctest in your testlog - 
that's helpful and gives some extra confidence.

Re: [v3 PATCH 1/6] drivers: reset: TI: SoC reset controller support.

2014-07-22 Thread Suman Anna
Hi Dan,

On 07/17/2014 11:45 AM, Murphy, Dan wrote:
 The TI SoC reset controller support utilizes the
 reset controller framework to give device drivers or
 function drivers a common set of APIs to call to reset
 a module.
 
 The reset-ti is a common interface to the reset framework.
  The register data is retrieved during initialization
  of the reset driver through the reset-ti-data
 file. The array of data is associated with the compatible from the
 respective DT entry.

Outdated commit description, this is no longer correct.

 
 Once the data is available then this is derefenced within the common
 interface.
 
 The device driver has the ability to assert, deassert or perform a
 complete reset.
 
 This code was derived from previous work by Rajendra Nayak and Afzal Mohammed.
 The code was changed to adopt to the reset core and abstract away the SoC 
 information.

Nokia N900 FB regression?

2014-07-22 Thread Aaro Koskinen
Hi,

Somewhere between 3.16-rc2 and rc6 (I was on holidays...) I noticed
the framebuffer stopped working on N900 (nothing on screen).

I bisected this to 913fd66e9809e93e06d5bbd49cf99a6cdbee (ARM: dts:
Enable twl4030 off-idle configuration for selected omaps).
With this commit reverted, I can see the Tux again with 3.16-rc6.

Any ideas?

This seems to be the case of no boot. Perhaps compatible functions are
incorrect?
I am new so asking a maintainer may be better but seems the idle function set
here turns off your frame butter. I would also test this on the beagleboard xm
as this patch may affect it too.

  Hello,
  
  The OMAP3 ISP driver was the only user of the OMAP IOVMM API. Now
  that is has been ported to the DMA API, remove the unused virtual

  The removal is split in three patches to ease upstream merge. The
  first patch removes the omap-iovmm driver, the second patch
  removes setting of now unused platform data fields from arch code,
  and the last patch cleans up the platform data structure.
  
  Thanks for the revised series, it looks good. I have also tested the
  series on OMAP3, OMAP4 and OMAP5.
  
  For the changes in the entire series,
  Acked-by: Suman Anna s-a...@ti.com
  
  Thank you.
  
  I'd like to get at least the first patch merged in v3.17. To avoid
  splitting the series across three kernel versions, it would be
  nice to also merge at least the second patch for v3.17. If there's
  no risk of conflict everything could be merged in one go through
  the ARM SoC tree. Otherwise a stable branch with patch 1/3 will be
  needed to base the arch change on.
  
  Joerg, Tony, how would you like to proceed ?
  
  The v3.17 merge window is getting close, it's probably too late to
  merge patch 2/3. Joerg, could you please take 1/3 in your tree for
  v3.17 ? 2/3 and 3/3 would then get in v3.18. Tony, how would you like
  to proceed for those ?
  
  How about Joerg maybe do an immutable branch against v3.16-rc1
  with just these three patches and merge it into your tree?
  
  That way I too can merge the minimal branch in if there are conflics.
  If that works for Joerg, then for arch/arm/*omap* changes:
  
  Acked-by: Tony Lindgren t...@atomide.com
  
  I've created an immutable branch (or, rather, immutable until the changes
  reach mainline, at which point I will remove the branch) on top of
  v3.16-rc1 with just the three patches from this series. You can find it
  at.
  
  git://linuxtv.org/pinchartl/media.git omap/iommu
  
  Tony, is there still time to get this (and especially patch 2/3, which
  touches arch/ code) in v3.17 ?
 
 Yes as long as Joerg is OK to merge that branch in :)

Are you ? :-)

Since we are introducing empty lists in this patch, I guess
this can go in the same patch.

Re: [PATCH 0/2] ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists

 This series add seperate ocp interface lists that are specific to dra74x

 Adding support for soc_is_dra74x() and soc_is_dra72x() in order to 
 differentiate
 between dra74x and dra72x and pass the respective ocp interface lists.

 Verified on dra74x evm and dra72x evm using 3.16-rc5 based mainline kernel.

 Before:
 dra74x : http://paste.ubuntu.com/7802364/ 
 dra72x : http://paste.ubuntu.com/7802334/ (Kernel panic)

 After-
 dra74x : http://paste.ubuntu.com/7802340/
 dra72x : http://paste.ubuntu.com/7802338/ (booted)

Thanks..
 
 BUT, I suggest a follow up series to do exactly the same (moving stuff
 that are not common from dra7.dtsi to dra72x.dtsi and 74x.dtsi) as
 well to ensure that dts indicates exactly the same information (only
 the applicable IPs are present in dts).
The separation of dra72x.dtsi and dra74x.dtsi is already happened and the patch 
is
already present in mainline[1].
Looks like usb_otg_ss4 is still present in dra7.dtsi, but this should go into 
dra74x.dtsi.
I ll take it up.
