Hi all,

This patch series adds support for
the imx8q video encoder and decoder
via the VPU block present in imx8q platforms.
Currently, support for IMX8QXP and IMX8QM is included.
NAK.

Nicolas gave you important feedback on your first version, and you have
ignored that, as far as I can see.

It seems very rude to do that, please avoid ignoring feedback from reviewers
and maintainers.

Please move the driver to drivers/media/platform/amphion, rename the driver
name, compatible, etc. This is the same case as CODA driver, Hantro driver, etc.

I sincerely hope you will not ignore this, and then send a v8 version ;-)

Thanks!

Hi Ezequiel,
   I'm sorry that I missed the message,  I'll check and make the adjustments

Thanks

It features decoding for the following formats:
- H.264
- HEVC
- MPEG4
- MPEG2
- VC1
- VP8

It features encoding for the following formats:
- H.264

The driver creates a separate device node for the encoder and decoder.

Changelog:

v7
- fix build warnings with W=1 reported by kernel test robot

v6:
- rename V4L2_PIX_FMT_NT8 to V4L2_PIX_FMT_NV12_8L128
- rename V4L2_PIX_FMT_NT10 to V4L2_PIX_FMT_NV12_10BE_8L128

v5:
- move some definition from imx_vph.h to videodev2.h
- remove some unnecessary content
- add some documentation descriptions
- pass the lateset v4l2-compliance test

v4:
- redefine the memory-region in devicetree bindings documentation
- use v4l2's mechanism to implement synchronize queuing ioctl
- remove the unnecessary mutex ioctl_sync
- don't notify source change event if the parameters are same as
previously established
- add flag V4L2_FMT_FLAG_DYN_RESOLUTION to decoder's capture format

v3:
- don't make vpu device node a simple-bus
- trigger probing vpu core in the driver
- remove unnecessary vpu core index property

v2:
- fix dt bindings build error
- split driver patch into several parts to avoid exceeding bytes limit
