Support the graphics clock controller for SM8750 for Graphics SW driver to use the clocks. GXCLKCTL (Graphics GX Clock Controller) is a block dedicated to managing clocks for the GPU subsystem on GX power domain. The GX clock controller driver manages only the GX GDSC and the rest of the resources of the controller are managed by the firmware. The Graphics GX clock controller is a reuse of the Kaanapali SW driver. Changes in v3: - SM8750 GX controller is reuse of Kaanapali SW driver, update the bindings. - Remove 'qcom,sm8750-gxcc.yaml' as it reuses the driver. - Cleanup the 'gpucc-sm8750.c' to remove the GX clock controller reference. - Add the corresponding changes in Makefile for gxclkctl-kaanapali.o - Update the device node for GX clock controller. - Link to v2: https://lore.kernel.org/all/20250723-topic-8750_gpucc-v2-0-56c93b84c390@oss.qualcomm.com/ (local) Changes in v2: - gxcc bindings: remove double colon & list the names for power-domains - Link to v1: https://lore.kernel.org/r/20250708-topic-8750_gpucc-v1-0-86c86a504d47@oss.qualcomm.com (local) Signed-off-by: Taniya Das <redacted> --- Konrad Dybcio (3): dt-bindings: clock: qcom: Add SM8750 GPU clocks clk: qcom: Add a driver for SM8750 GPU clocks arm64: dts: qcom: sm8750: Add GPU clock & IOMMU nodes .../bindings/clock/qcom,kaanapali-gxclkctl.yaml | 1 + .../bindings/clock/qcom,sm8450-gpucc.yaml | 2 + arch/arm64/boot/dts/qcom/sm8750.dtsi | 64 +++ drivers/clk/qcom/Kconfig | 9 + drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/gpucc-sm8750.c | 472 +++++++++++++++++++++ include/dt-bindings/clock/qcom,sm8750-gpucc.h | 50 +++ 7 files changed, 599 insertions(+) --- base-commit: 350adaf7fde9fdbd9aeed6d442a9ae90c6a3ab97 change-id: 20260217-gpucc_sm8750_v2-866576675fa0 Best regards, -- Taniya Das [off-list ref]
