Yes, will do so, thanks! greg k-h
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].
