Hi everyone,
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 reverts the driver name field change. It also makes it
explicit that the field really should match the driver name.
Patch 2 changes the value for the card name, making it a free form
string that includes the SoC model.
Patch 3 removes setting the bus_info field, instead using the default
value derived from the underlying |struct device| as set by the V4L2
core.
Patches 4 through 6 do the same as 1 through 3 respectively, but for
the encoder side.
This series is based on next-20220701, 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
