Eh, how did you test this patch?
The GCC_DISP_AHB_CLK clocks are not modelled by the clock driver
currently so nothing is guaranteeing them to be enabled if we were to
apply this patch. They just happen to be left on by the bootloader on
some machines currently (well at least one of them is on one machine).
So this series is broken and should not be applied.
NAK.
Also, please CC me on sc8280xp and X13s related patches.
