Add GPU clock controller (GPUCC) and GX clock controller (GXCLKCTL)
support for the Qualcomm Hawi SoC.
The GPUCC provides clocks, resets and power domains for the GPU
subsystem. The GXCLKCTL manages only the GX GDSC; remaining resources
are handled by firmware. Hawi's GX clock controller reuses the existing
gxclkctl-kaanapali driver via a fallback compatible
("qcom,hawi-gxclkctl", "qcom,kaanapali-gxclkctl"), so no driver change
is needed unless Hawi-specific behaviour is required later.
Changes in v2:
- dt-bindings: qcom,hawi-gpucc: reorder power-domains and required-opps
to MX, CX, GMXC to match existing GPUCC bindings (suggested by
Krzysztof Kozlowski)
- dt-bindings: qcom,hawi-gpucc: shorten required-opps item descriptions
(suggested by Krzysztof Kozlowski)
- clk: qcom: gpucc-hawi: collect Reviewed-by from Taniya Das
- Rebased onto linux-next (20260730)
