[PATCH v3 00/17] Fix Qcom UFS PHY clocks

[Manivannan Sadhasivam]

Hi,

This series fixes the clocks supplied to QMP PHY IPs in the Qcom SoCs. All
of the Qcom SoCs except MSM8996 require 3 clocks for QMP UFS:

* ref - 19.2MHz reference clock from RPM/RPMh
* ref_aux - Auxiliary reference clock from GCC
* qref - QREF clock from GCC or TCSR (TCSR since SM8550)

MSM8996 only requires 'ref' and 'qref' clocks.

Hence, this series fixes the binding, DT and GCC driver to reflect the
actual clock topology.

Note that the clock topology is not based on any downstream dts sources (even
they are not accurate). But rather based on information from Qcom internal
documentation and brain dump from Can Guo.

Testing
=======

Tested on Qualcomm RB5 development board based on SM8250 SoC. I don't
expect this series to break other SoCs too.
