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

[Peter Griffin]

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.

[PATCH v3 1/5] dt-bindings: clock: google,gs101-clock: fix alphanumeric ordering

[Peter Griffin]

Ensure children of cmu_top have alphanumeric ordering. Top is special as it
feeds all the other children CMUs. This ordering then matches the
clk-gs101.c file.

[PATCH v3 5/5] arm64: dts: exynos: gs101: add cmu_dpu and sysreg_dpu dt nodes

[Peter Griffin]

Enable the cmu_dpu clock management unit. It feeds some of the display
IPs. Additionally add the sysreg_dpu node which contains the
BUSCOMPONENT_DRCG_EN and MEMCLK registers required by cmu_dpu to enable
dynamic root clock gating of bus components.

Thanks, applied.
It is however very late in the cycle, so there is a chance this will
miss the merge window. If this happens, I will keep it for the next
cycle (no need for resending).
