[PATCH v9 00/10] Add support for videocc, camcc, dispcc and gpucc on Qualcomm QCS615 platform

[Taniya Das]

Add support for multimedia clock controllers on Qualcomm QCS615 platform.
Update the defconfig to enable these clock controllers.

Global clock controller support
https://lore.kernel.org/all/20241022-qcs615-clock-driver-v4-0-3d716ad0d987@quicinc.com/

Changes in v9:
- Reuse the qcom,sm6350-camcc.yaml for QCS615 [Vladimir]

Changes in v7:
- Update DT bindings for CAMCC, DISPCC, VIDEOCC, GPUCC to remove the
  common bindings and add reference to "qcom,gcc.yaml" [Krzysztof]
- Fix the following in the alpha pll code [Bjorn]
	- double space removal in clk_alpha_pll_slew_set_rate
	- fix the alpha_width from dynamic to 'ALPHA_REG_BITWIDTH'
	- cleanup the programming of lower/upper_32_bits of 'alpha'
	- update the comment for 'mb()'
- Link to v6: https://lore.kernel.org/all/20250313-qcs615-v5-mm-cc-v6-1-ebf4b9a5e916@quicinc.com/

Changes in v6:
- Remove wrongly RB-By tags which got introduced in v4 and was carried
  to v5 as well.
- Adding the reference where the tags were added and dropped.

[PATCH v9 01/10] clk: qcom: clk-alpha-pll: Add support for dynamic update for slewing PLLs

[Taniya Das]

The alpha PLLs which slew to a new frequency at runtime would require
the PLL to calibrate at the mid point of the VCO. Add the new PLL ops
which can support the slewing of the PLL to a new frequency.

Since you read the value of PLL_MODE back, the barrier is unnecessary

Here however, the write may not arrive at the clock controller before you

I'm going to assume this is not the same ramp controller as:

This ramp controller is at the RCG level, which was very specific to
8976 and not same at the CC level.

Okay, I can introduce a readback, but as per the PLL code we have been
using mb() at most places. But I am okay to update it.
