[v3] gs101: Add support for Display Process Unit (DPU) clocks

[PATCH v3 0/5] gs101: Add support for Display Process Unit (DPU) clocks

Posted by Peter Griffin 3 weeks, 3 days ago

Hi folks,

This series adds support for the Display Process Unit (DPU) Clock
Management Unit (CMU) aka CMU_DPU found on gs101. These will be used for
the IOMMU and display enablement.

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

regards,

Peter.
