Why not just CLK_IGNORE_UNUSED? As I understand this gate clock can be
used to disable PCLK (bus clock) provided to the whole CMU_PERIC0.
Aren't there any valid cases for disabling this clock, like during
some PM transitions? For Exynos850 clock driver I marked all clocks of
this kind as CLK_IGNORE_UNUSED and it works fine. In other words: I'd
say CLK_IS_CRITICAL flag is more "strong" than CLK_IGNORE_UNUSED, and
requires better and more specific explanation, to make sure we are not
abusing it. And I'm not sure this is the case.
The same goes for the rest of clocks marked as CLK_IS_CRITICAL in this
patch. Please check if maybe using CLK_IGNORE_UNUSED makes sense for
any of those as well.
