Please disregard above two patches. It turns out that many more changes are
required to fix mess with rotation clocks and reset. I sent separate patch
series: http://lists.infradead.org/pipermail/linux-arm-kernel/2020-February/
710242.html
Comments on the rest of the series are welcome, though.
Best regards,
Jernej
