Laurent Pinchart 112eee0c03 [media] omap3isp: Refactor modules stop failure handling
Modules failing to stop are fatal errors for the preview engine only.
Flag that condition separately from the other stop failures to prepare
support for more fatal errors.

Laurent Pinchart 661112cb7e [media] omap3isp: Cancel streaming when a fatal error occurs
When a fatal error that prevents any further video streaming occurs in a
pipeline, all queued buffers must be marked as erroneous and new buffers
must be prevented from being queued. Implement this behaviour with a new
omap3isp_pipeline_cancel_stream() function that can be used by
submodules to cancel streaming.

Laurent Pinchart fd8308b42c [media] omap3isp: Use devm_ioremap_resource()
Replace devm_request_mem_region() and devm_ioremap_nocache() with
devm_ioremap_resource(). The behaviour remains the same and the code is
simplified.

Sylwester Nawrocki f8e2ff2621 [media] omap3isp: Modify clocks registration to avoid circular references
The clock core code is going to be modified so clk_get() takes
reference on the clock provider module. Until the potential circular
reference issue is properly addressed, we pass NULL as the first
argument to clk_register(), in order to disallow sub-devices taking
a reference on the ISP module back trough clk_get(). This should
prevent locking the modules in memory.

Russell King 224ddca0f2 DMA-API: media: omap3isp: use dma_coerce_mask_and_coherent()
The code sequence:
	isp->raw_dmamask = DMA_BIT_MASK(32);
	isp->dev->dma_mask = &isp->raw_dmamask;
	isp->dev->coherent_dma_mask = DMA_BIT_MASK(32);
bypasses the architectures check on the DMA mask.  It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.

Laurent Pinchart 6d1aa02f10 omap3isp: Set cam_mclk rate directly
Now that the cam_mclk rate changes are back-propagated to dpll4_m5_ck we
can set the cam_mclk rate directly instead of manually setting the rate
of the parent clock.

Linus Torvalds d8c532c407 Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:

 - Missing MAINTAINERS entries were added for several drivers

 - Adds V4L2 support for DMABUF handling, allowing zero-copy buffer
   sharing between V4L2 devices and GPU

 - Got rid of all warnings when compiling with W=1 on x86

 - Add a new driver for Exynos hardware (s3c-camif)

 - Several bug fixes, cleanups and driver improvements

Configure CSI-2 phy based on platform data in the ISP driver. For that, the
new V4L2_CID_IMAGE_SOURCE_PIXEL_RATE control is used. Previously the same
was configured from the board code.

Tony Lindgren c8d35c84f5 ARM: OMAP2+: Move plat/iovmm.h to include/linux/omap-iommu.h
Looks like the iommu framework does not have generic functions
exported for all the needs yet. The hardware specific functions
are defined in files like intel-iommu.h and amd-iommu.h. Follow
the same standard for omap-iommu.h.

This is needed because we are removing plat and mach includes
for ARM common zImage support. Further work should continue
in the iommu framework context as only pure platform data will
be communicated from arch/arm/*omap*/* code to the iommu
framework.

Mauro Carvalho Chehab 2c3fb08b3f [media] rename drivers/media/video as .../platform
The remaining drivers are mostly platform drivers. Name the
dir to reflect it.

It makes sense to latter break it into a few other dirs.
