[PATCH v1 0/2] Fix display on second resume on 5250-snow

Hi,

as discussed in [0], currently on the second resume from memory the
display is broken on Snow boards (ARM Samsung Series 3 Chromebook).

The reason is that on resume the contents of register SRC_TOP3 aren't
what the kernel thinks they are because the HW (or FW) is doing some
clock reparenting beneath our feet.

This series tasks the kernel to do the reparenting itself so that the HW
state always matches the kernel's internal state.

Thanks,

Tomeu
