==============
  Introduction
==============

The purpose of this series is to add the driver for video codec hw
embedded in the Mediatek's MT8173 SoCs.
Mediatek Video Codec is able to handle video decoding of in a range of
formats.

This patch series add Mediatek block format V4L2_PIX_FMT_MT21, the
decoder driver will decoded bitstream to
V4L2_PIX_FMT_MT21 format.

This patch series rely on MTK VPU driver in patch series "Add MT8173
Video Encoder Driver and VPU Driver"[1]
and patch "CHROMIUM: v4l: Add V4L2_PIX_FMT_VP9 definition"[2] for VP9
support.
Mediatek Video Decoder driver rely on VPU driver to load, communicate
with VPU.

Internally the driver uses videobuf2 framework and MTK IOMMU and MTK SMI
both have been merged in v4.6-rc1.

Hmm... I'm not seeing the firmware for this driver at the
linux-firmware tree:

https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/log/

Tiffany. Can you check the license and add the firmware to linux-firmware?

For the information, both encoder and decoder drivers require the
firmware to work.

Nor I'm seeing any pull request for them. Did you send it?
I'll only merge the driver upstream after seeing such pull request.

Mauro, are you confusing the decoder and encoder driver? I haven't
thoroughly reviewed the decoder driver
yet, so there is no pull request for the decoder driver.

The only pull request I made was for the encoder driver.

Regards,

        Hans
