[PATCH v5 1/3] dt-bindings: clock: qcom: Add SM8750 GPU clocks

From: Taniya Das <hidden>
Date: 2026-03-05 10:40:23
Also in: linux-arm-msm, linux-clk, lkml
Subsystem: arm/qualcomm mailing list, common clk framework, open firmware and flattened device tree bindings, qualcomm clock drivers, the rest · Maintainers: Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Bjorn Andersson, Linus Torvalds

From: Konrad Dybcio <redacted>

The SM8750 features a "traditional" GPU_CC block, much of which is
controlled through the GMU microcontroller. GPU_CC block requires the MX
and CX rail control and thus add the corresponding power-domains and
require-opps. Additionally, there's an separate GX_CC block, where
the GX GDSC is moved.

Update the bindings to accommodate for SM8750 SoC.
