Still feels fishy to me that it was decided to have this file instead
of re-using existing Exynos constants. For example, in Exynos850 I
used common constants and it was ok, but it's not ok for this SoC,
althought they look *identical* in a sense of pinctrl. And all those
constants already exist, also identical. So I wonder why something
like this shouldn't be done for Exynos850 as well. But ok.

Please check commit f4324583cd4d ("arm64: dts: exynos: move aliases to
board in Exynos850"). At least for Exynos850 the serial alias was
moved to the board dts by Krzysztof.

Don't you already have real USI/UART clocks implemented in your clock driver?

Krzysztof, can you please advice which scheme is preferred right now:
sorting by name or by address? I saw your patch for dts style doc, but
just want to know the current state of affairs.

I can't see this compatible in USI driver. Does it make sense to add it there?

The same concern as above. I think I saw those clocks already
implemented in gs101 clock driver.

Doesn't CMU_APM take any clocks from CMU_TOP?

Just a suggestion: it might be relatively simple to add syscon-reboot
node in pmu_system_controller, and it might just work. One more
feature for free! :)
