Subject: [PATCH v3 00/14] Enable GPU for SM8150 and SM8250

This series adds the missing clock drivers and dts nodes to enable
the GPU on both SM8150 and SM8250.

Note an extra drm/msm patch [1] is required for SM8250.

As noted by Dmitry, GMU init fails with newer firmware, needs this patch [2].

Changes in V2:
* Added "clk: qcom: gcc: fix sm8150 GPU and NPU clocks" to fix the newly added
  SM8150 GPU gcc clocks
* Added "Fixes:" tag to "clk: qcom: clk-alpha-pll: remove unused/incorrect PLL_CAL_VAL"
* Added yaml schemas to gpucc dt-bindings patches
* Added "clk: qcom: add common gdsc_gx_do_nothing_enable for gpucc drivers" and changed
  gpucc patches to use it.
* Removed CLK_IS_CRITICAL from gpu_cc_ahb_clk
* Added missing rpmh regulator level for sm8250 GPU clock levels
* Use sm8150/sm8250 iommu compatibles in dts
* Add gcc_gpu_gpll0_clk_src/gcc_gpu_gpll0_div_clk_src to gpucc clocks in dts

Changes in V3:
* Combined gpucc yaml bindings into one
* Removed some unused clocks from gpucc drivers to move closely match other gpucc
* Use parent_data instead of parent_names
