This series aims at enabling USB on QCS8300 which has 2 USB controllers.
The primary controller is SuperSpeed capable and secondary one is
High Speed only capable. Both the High Speed Phys are Femto phys and the
SuperSpeed Phy is a QMP Uni Phy.

Base DT Support has been added for both controllers while only one has
been enabled on Ride Platform. The primary controller has been configured
in device mode. The secondary controller will be enabled in host mode post
addition of SPMI Node which allows control over PMIC Gpios for providing
vbus to connected peripherals.

This series depends on the following series ACKed by upstream maintainers:
