[PATCH v4 1/8] dt-bindings: arm: mediatek: mmsys: Add support for MT8195 VPPSYS
Posted by Moudy Ho 1 year, 9 months ago 
For MT8195, VPPSYS0 and VPPSYS1 are 2 display pipes with
hardware differences in power domains, clocks and subsystem counts,
which should be determined by compatible names.

This landed in today's linux-next causing the following binding
warnings. Is this a fix? Only fixes for 6.2 should be added during the
merge window.

No it's not a fix, it's queued for the next -rc phase. I didn't know of the 
limitation of linux-next only allowing fixes in the merge window.

Actually the patch is wrong. It shouldn't include "mediatek,mt8195-mmsys" as 
fallback for mediatek,mt8195-vppsys[0,1].

I'll revert the whole series from v6.2-tmp/dts64 and v6.2-tmp/soc

Matthias

Stephen asks for it every time. Now it is in separate email:

https://lore.kernel.org/linux-next/20221213120359.47fc3cad@canb.auug.org.au/

Previously it was in each linux-next announcement:
https://lore.kernel.org/linux-next/20220527164940.6ef5b25e@canb.auug.org.au/

Thanks. Please, drop all material for next cycle from linux-next.

Best regards,
