Subject: [PATCH 00/16] Fix Qcom UFS PHY clocks

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.

Testing
=======

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