Add support for PLL found in Qualcomm SDX65 platforms which is used to
provide clock to the Cortex A7 CPU via a mux. This PLL can provide high
frequency clock to the CPU above 1GHz as compared to the other sources
like GPLL0.
In this driver, the power domain is attached to the cpudev. This is
required for CPUFreq functionality and there seems to be no better place
to do other than this driver (no dedicated CPUFreq driver).
This tells what the driver is doing but not essentially what this patch does
i.e., you need to mention how the SDX65 PLL is added to the driver. Since you
are reusing the existing driver, this needs to be mentioned.
Will update.

I think here also you can just reuse the "qcom,sdx55-a7pll" compatible.
Ok, Will update. Thanks!
Thanks,
