Hi everyone,
This is v2 of my mtk-vcodec capabilities fixes series.
Changes since v1:
- Squashed 3 patches into one, as Hans recommended
The previous round of changes to the mtk-vcodec driver's returned
capabilities caused some issues for ChromeOS. In particular, the
ChromeOS stateless video decoder uses the "Driver Name" field to
match a video device to its media device. As the field was only
changed for the video device and not the media device, a match
could no longer be found.
While fixing this, I found that the current info used for the fields
don't make a lot of sense, and tried to fix them in this series.
Patch 1 fixes the capabilities for the decoder. The driver name field
change is reverted and made explicit that the field really should match
the driver name. The card name is made a user readable string that
includes the SoC model. The bus_info field is dropped and the default
value from the V4L2 core is used.
Patch 2 does the same, but for the encoder size. And since the last
reference to MTK_VCODEC_DRV_NAME is removed, the macro is removed as
well.
This series is based on next-20220708, and was tested on mainline on
MT8183 Juniper, and on ChromeOS v5.10, on which we have a whole bunch
of backports pending, on MT8195 Tomato.
Please have a look.
Thanks
