Hi Arnd,
Hi Olof,
Please have a look on the following SoC driver patches.
Highlight in this pull request is, that we got the mmsys mess cleaned up. In
MediaTek "mmsys" is IP block which holds multi-media devices and their
corresponding clocks muxes. In the past the clocks and multi-media system used
the same compatible (ouch) which broke graphics quite some time ago. After
several different approaches how to fix the mess, we now got a mmsys SoC driver
which is responsible for probing the clock and multi-media parts of the IP block.
This now allows us to have graphics support on the MT8173 based Chromebooks,
which is nice and will allow others developers who don't have a servo board to
debug the device and (hopefully) help to get the missing bits upstream.
The effort is not yet finished, but I hope for v5.9 we will see also graphics
support on the Bananapi-R2.
Regards,
Matthias
