Subject: [PATCH 0/4] gs101: Add support for Display Process Unit (DPU)
 clocks

Hi folks,

This series adds support for the Display Process Unit Clock Management Unit
(CMU_DPU) found on gs101. I've based this on top of the automatic clock
series to avoid conflicts [1].

As all the patches will go via Krzysztof tree it has been sent as one
series.

regards,

Peter.
