However these clocks are essential for the exynos power domains operation. There are more dependencies between the clocks and the power domains which adding of those properties does not cover. And we'll need to address those dependencies somehow. Anyway, the subject patch looks OK to me, given that support for clocks/ clock-names in the exynos power domain device nodes has been merged for quite long already. The entire feature has been merged without PM or clk subsystem maintainer ACK, I don't see a reason not to merge this small addition of more clocks, especially that it fixes a real bug.
