[PATCH] media: coda: Fix probe() if reset controller is missing
Commit 39b4da71ca334354f30941067f214ea2f2b92f3e (reset: use ENOTSUPP
instead of ENOSYS) changed return value for reset controller if it missing.
This patch changes the CODA driver to handle this value.

Re: Kconfig symbol MX1_VIDEO
Fri, 27 Jun 2014 10:18:19 +0200 от Paul Bolle pebo...@tiscali.nl: Alexander, Your patch [media] media: mx1_camera: Remove driver landed in today's linux-next (ie, next-20140627), as commit 90b055898e9d. It is archived at http://www.spinics.net/lists/linux-media/msg76764.html . It removes the Kconfig symbols MX1_VIDEO en VIDEO_MX1. It only removes the code depending on VIDEO_MX1 (ie, in drivers/media/platform/soc_camera). A previous version of that patch is archived at http://www.spinics.net/lists/linux-media/msg76432.html . (Please, next time you submit a second version of a patch mark it as a v2 and add some info below the --- marker about the differences to the first version.) That previous version removed the code depending on both symbols. But a quick glance at the discussion about that patch shows that you were asked to not remove the code depending on MX1_VIDEO (ie, in arch/arm/mach-imx/). Would you perhaps know whether a patch to remove the arch/arm/mach-imx/ code is pending somewhere? Patch to remove MX1_VIDEO part from arch/arm/mach-imx is scheduled. I expect to update the Shawn git repository to the linux-next branch. ---

The overall structure of the eMMA module is slightly different.
As for the part of the PrP, according to the datasheet they are compatible.
Then can we please have all the valid compatible strings listed at the
'compatible' property's description above ? I think it is useful to have
an indication to which SoC each of them apply in documentation of the
binding.
Traditionally, i.MX drivers uses youngest chip for compatibility string.
The best example of this: drivers/bus/imx-weim.c

Can this patch be applied through arm-soc (imx) tree if it will be approved by the linux-media maintainers? Yes, it can, if linux-media maintainers want. But I still prefer to two patches, since I do not see any thing requiring it be one. Doing that will ensure we do not run into any merge conflicts. ARM part and linux-media part are interconnected by using single header linux/platform_data/camera-mx1.h. So removing a driver in a separated patch will touch ARM part in any case. ---

[PATCH 1/3] media: mx2-emmaprp: Cleanup internal structure
There are no need to store resource struct and IRQ in the driver
internal structure.
This patch remove these fields and improve error handling by using
proper return codes from devm_ioremap_resource() and devm_request_irq().
