[PATCH v3 0/3] Add support for GPUCC and GXCLK for SM8750

[Taniya Das <taniya.das@oss.qualcomm.com>]

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/

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
