Subject: [PATCH v2 00/11] soc: qcom: add UCSI function to PMIC GLINK

The PMIC GLINK interface offers an UCSI endpoint for newer
SoCs, the UCSI exchange is necessary to configure the USB-C
port USB role and altmode on the SM8450 HDK and SM8550 MTP
boards.
Since the DT description is the same, support for SM8350 HDK
is also added.

This patchset focuses on USB and disables altmode support
on those 2 SoCs until DP altmode over the combo phy is
supported.

Depends on PMIC Glink patchset at [1].
