This chunk is new since the split out v10 series[1]. I see that you dropped
krzk's Reviewed-by presumably because of the new chunk. However I don't
see a changelog.

I'm collecting patches up for a clk pull to Stephen. (I'm not sure if
he's going to pull but I'm going to try.) I'm not going to include this
series until I see a Reviewed-by by one of the dt maintainers on the new
patch.
