Hi,

This series adds interconnect support to Qcom UFS driver. Interconnect support
is added to Qcom UFS driver for scaling the interconnect path dynamically. This
is required to avoid boot crash in recent SoCs and also to save power during
runtime. More information is available in patch 2/2.

Credits
=======

This series is a continuation of previous work by Brian Masney [1].

Testing
=======

This series is tested on 96Boards RB3 (SDM845 SoC) and RB5 (SM8250 SoC)
development boards.

NOTE: This series is a spin-off from previous OPP and interconnect series:
https://lore.kernel.org/all/20230720054100.9940-1-manivannan.sadhasivam@linaro.org/

Since the devicetree patches are already merged to Qcom tree, they are excluded
from this series.

Thanks,
Mani
