Looks good, feel free to add:

Reviewed-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> for patches
1...3/9, 5...7/9

and Tested-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> for patch 1/9

Hopefully we can gather more Acks and merge it for 3.11.

I have already used this API for our MIPI CSI-2/DSIM DPHYs driver,
the RFC patch series can be found at [1].

Thanks,
Sylwester
