I'm not very happy with the approach of testing against the reg property to
decide which version of the two mmsys devices we are probing. I think a better
approach would be, if we would have added some mediatek specific ID to the
device tree binding (or use a two compatibles?).
But as we are at v20 I think it wouldn't be fair to ask for such an instrusive
change. So I'll take this patch now, but maybe we can discuss if we can't do
better in a follow-up patch. Especially I don't think it's a good approach to
check for the io_start in the DRM driver. Couldn't we pass the information about
which of the two mmsys blocks we are calling from through the mediatek-drm
platform device spefic data?
I also had a look into the vdosys1 series to better understand why we need to do
things as we do them. But honestly I wasn't able to really understand the
implication of the patch that adds 'multi mmsys support' [1]. For this looks
like a several patches that got squashed into one. But as I don't have to
maintain that it is not my call to complain, the patch has the needed reviews.
For this patch, now applied to v5.18-next/soc
Thanks for all people implicated.
Regards,
Matthias
