[PATCH v4 0/3] Enable UFS on QCS615

[PATCH v4 0/3] Enable UFS on QCS615

[Xin Liu]

From: Sayali Lokhande <quic_sayalil@quicinc.com>

Add UFS support to the QCS615 Ride platform. The UFS host controller and
QMP UFS PHY hardware of QCS615 are derived from SM6115. Include the
relevant binding documents accordingly. Additionally, configure UFS-related
clock, power, and interconnect settings in the device tree.

This patch series depends on below patch series:
