From: Yunfei Dong <yunfei.dong@mediatek.com>
MT8183's codec firwmare is run by a different remote processor from
MT8173. While the firmware interface is basically the same, the way to
invoke it differs. Abstract all firmware calls under a layer that will
allow us to handle both firmware types transparently.

rproc_boot() is part of the remoteproc subsystem. scp_get_rproc() is
part of the mtk_scp driver, which is present upstream. This patch also
adds a dependency on MTK_SCP in Kconfig, which ensures both functions
are available.

Firmwares for encoders newer than MT8173 will include an ABI version
number in their initialization ack message. Add the capacity to manage
it and make initialization fail if the firmware ABI is of a version that
we don't support.
For MT8173, this ABI version field is reserved and thus undefined ; thus
ignore it on this chip. There should only be one firmware version available
for it anyway.

Different chips have different supported bitrate ranges. Move the min
and max supported bitrates to the platform data.

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.

vidioc_try_fmt() does clamp height and width when called on the OUTPUT
queue, so clamping them prior to calling this function is redundant. Set
the queue's parameters after calling vidioc_try_fmt() so we can use the
values it computed.

vidioc_try_fmt clamps height and width only when f->type ==
V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE
Does this cleanup pass v4l2 compliance test?
I recall compliance test will try different fmt and make sure driver
response enough information?

The mediatek codecs can use either the VPU or the SCP as their interface
to firmware. Reflect this in the DT bindings.

Would it be possible to add the support in
arch/arm64/boot/dts/mediatek/mt8183.dtsi ?
Given the driver is stateful it should be possible
for anyone to test it with standard userspace
such as GStreamer.
Is it possible for the firmware to be pushed to linux-firmware ?
Thanks,
Ezequiel

Certainly.

The firmware is already there:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=3c213aa59661c4641f0c2166a315140ac0445230
