I have confirmed that this CL does not introduce any regression with
v4l2-compliance.

I remember that passing compliance tests is required for upstream.
The tests try to make sure that all V4L2 driver implement interfaces in
the same way.
So user space applications could find/enumerate HW capability.

This should not change the behavior towards userspace at all (it's
just moving data around and making it more flexible), so the test
results should not be affected either.

[PATCH 06/10] media: mtk-vcodec: venc: specify supported formats per-chip

2020-05-20 Thread Alexandre Courbot

Different chips have different supported bitrate ranges. Move the list
of supported formats to the platform data, and split the output and
capture formats into two lists to make it easier to find the default
format for each queue.
