media: mtk-vcodec: venc: fix return value when start_streaming fails

2021-09-30T08:07:53+00:00

In case vb2ops_venc_start_streaming fails, the error value
is overwritten by the ret value of pm_runtime_put which might
be 0. Fix it.

media: mtk-vcodec: fix warnings: symbol XXX was not declared

2021-09-30T08:07:42+00:00

Fixes sparse warnings:
- warning: symbol 'mtk_vdec_8173_pdata' was not declared. Should it be
static?
- warning: symbol 'mtk_vdec_8183_pdata' was not declared. Should it be
static?

media: mtk-vcodec: vdec: add media device if using stateless api

2021-09-30T08:07:42+00:00

The stateless API requires a media device for issuing requests. Add one
if we are being instantiated as a stateless decoder.

media: mtk-vcodec: vdec: support stateless H.264 decoding

2021-09-30T08:07:42+00:00

Add support for H.264 decoding using the stateless API, as supported by
MT8183. This support takes advantage of the V4L2 H.264 reference list
builders.

media: mtk-vcodec: support version 2 of decoder firmware ABI

2021-09-30T08:07:41+00:00

Add support for decoder firmware version 2, which makes the kernel
responsible for managing the VSI context and is used for stateless
codecs.

media: mtk-vcodec: vdec: handle firmware version field

2021-09-30T08:07:41+00:00

Firmwares for decoders 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 does not exist ; thus ignore it on
this chip. There should only be one firmware version available for it
anyway.

media: mtk-vcodec: vdec: move stateful ops into their own file

2021-09-30T08:07:41+00:00

We are planning to add support for stateless decoders to this driver.
Part of the driver will be shared between stateful and stateless
codecs, but a few ops need to be specialized for both. Extract the
stateful part of the driver and move it into its own file, accessible
through ops that the common driver parts can call.

This patch only moves code around and introduces a set of abstractions ;
the behavior of the driver should not be changed in any way. Changes to
code styling has been done to accommodate 'checkpatch.pl --strict'.
