Introduce the UCSI PMIC Glink aux driver that communicates
with the aDSP firmware with the UCSI protocol which handles
the USB-C Port(s) Power Delivery.

The UCSI messaging is necessary on newer Qualcomm SoCs to
provide USB role switch and altmode notifications.

Nop, the QCOM_PMIC_GLINK is a build dependency, this can't be removed

Module name when built?

OK will add a follow-patch if needed

Thanks,

A follow-on patch can be sent, this is minor.
