Subject: [PATCH v6 0/3] Support for Qualcomm UFS QMP PHY on SDM845

This patch series adds support for UFS QMP PHY on SDM845 and the
compatible string for it. This patch series depends on the current
proposed QMP V3 USB3 UNI PHY support for sdm845 driver [1], on
the DT bindings for the QMP V3 USB3 PHYs based dirver [2], and also
rebased on updated pipe_clk initialization sequence [3]. This series
can only be merged once the dependent patches do.
