LGTM, I can apply this when the clk driver changes are merged (feel free
to let me know when that happens, in case I'm not paying attention.)
<bikeshed>
nit: This series (and previous ones) use MALI, but I believe the correct
way is Mali. Could you standarize on that throughout the series?
</bikeshed>
