[PATCH v3 00/14] media: mediatek: vcodec: support video decoder in mt8196

[Yunfei Dong]

This patch set adds support for the video decoder on the MediaTek MT8196
platform, leveraging the VCP microprocessor for enhanced performance. It
introduces new firmware interfaces for kernel-side communication with VCP,
adds MT8196 compatible, codec levels/profiles, and private data. Rewrites
the AV1 driver to support extended VSI structures, then change irq table
and cdf table size.

This patch set depends on "Add VCP support for mt8196"[1]

[PATCH v3 13/14] media: mediatek: decoder: fill av1 buffer size with picinfo

[Yunfei Dong]

The buffer size of y and c plane has been calculated in vcp/scp,
can fill each frame buffer size with picinfo directly.

Getting to bingo, two out of three redundant terms how to call DT
bindings. Drop YAML.

A nit, subject: drop second/last, redundant "dt-bindings". The
"dt-bindings" prefix is already stating that these are dt-bindings.
See also:
https://elixir.bootlin.com/linux/v6.17-rc3/source/Documentation/devicetree/bindings/submitting-patches.rst#L18

Write concise messages. "DT bindings schema yaml text file in kernel" is
not concise.

Why is this entire function written like this, and why does it exist
at all? You can store the chip name in the platform data for a compatible,
thereby avoiding a massive of_device_is_compatible if block because that's
what platform data is for.

The only place where this function is even used is in probe.

Just store it in your mtk_vcodec_match's .data struct and pull it from
dev->vdec_pdata. No need for the function.

I have already asked this to the dev working on some other MTK codec patchset,
and I think he already posted some proper refactoring (but had more changes to
finish it up). Mind, Yunfei, coordinating the effort on removing all the if/else
please ? We are doing the same code review again and again with every single
individual working on this driver.

regards,
Nicolas

I had already confirmed with kyrie, he had changed the compatible patch
in mt8189's patch set. So I just need to add mt8196's compatible.

mt8189's patch set is based on this patch set(8196's).

I will ask to work the other way around. Kiril patchset is very close to be
ready, and once in, you should be able to rebase on top.

Note that this patch is miss-ordered, you should implement all the VCP/firmware
part before you modify the probe function.

Nicolas

Kyrie's patchset is close to be merged, but mt8189 need to depend on
mt8196's change. We don't want to break the dependency currently.

Could
you please help to review other patches, I will reply in time as soon
as possible.

About the order to probe function, I will change it in next version.
