I think my old problem was with earlyprintk and a core clock getting
disabled. See (44ff025 clk: exynos5420: Remove aclk66_peric from the
clock tree description). I think I've seen others solve the same
problem with the concept of "critical clocks".
I agree that regulator and clock frameworks allow very different "hacks". ;)
