[PATCH 0/2] ARM: shmobile: defconfig: Enable HDMI input

[Niklas Söderlund]

Hi,

Now that the DT updates for HDMI in are in renesas-drivers I think it's 
a good time to enable the configuration needed to use HDMI input with 
shmobile_defconifg.

Niklas Söderlund (2):
  ARM: shmobile: defconfig: Enable CONFIG_VIDEO_ADV7604
  ARM: shmobile: defconfig: Enable CMA for DMA

[PATCH 1/2] ARM: shmobile: defconfig: Enable CONFIG_VIDEO_ADV7604

[Niklas Söderlund]

The adv7612 is used on Gen2 boards (Lager, Koelsch and Gose) for HDMI
input. Enable support for this chip in shmobile_defconfig.

[PATCH 2/2] ARM: shmobile: defconfig: Enable CMA for DMA

[Niklas Söderlund]

To be able to use VIN with larger frame sizes CMA memory are needed for
DMA. If this is not enabled trying to capture large frames can result in
errors such as:

rcar-vin e6ef0000.video: dma_alloc_coherent of size 8388608 failed

A CMA area of 64MB are needed for v4l2-compliance to pass on all formats
on the largest possible frame size of 2048x2048.

Thanks, I have queued these up for v4.11.
