I think this series is ready for merging.

As this touches both clk and drm, let's discuss the merge strategy.
My proposal:
  1. I queue patches 1-3 in an immutable branch with a signed tag,
     to be used as a base for the remaining patches,
  2. I queue patch 4 on top of 1 in renesas-clk for v6.19,
  3. The DRM people queue patches 5-7 on top of 1.

Does that sound fine for you?
Thanks!

Gr{oetje,eeting}s,
