DWC3 controller on Qualcomm SOCs has a Qscratch wrapper. Some of its uses are described below resulting in need to have a separate glue driver instead of using dwc3-of-simple: - It exposes register interface to override vbus-override and lane0-pwr-present signals going to hardware. These must be updated in peripheral mode for DWC3 if vbus lines are not connected to hardware block. Otherwise RX termination in SS mode or DP pull-up is not applied by device controller. - pwr_events_irq_stat support to check if USB2 PHY is in L2 state before glue driver proceeds with suspend. - Support for wakeup interrupts lines that are asserted whenever there is any wakeup event on USB3 or USB2 bus. - Support to replace pip3 clock going to DWC3 with utmi clock for hardware configuration where SSPHY is not used with DWC3.

# NOTICE: Make sure your glue layer doesn't depend on anything

# We want to keep this requirement in order to be able to compile
|
|
# the entire driver (with all its glue layers) on several architectures

# and make sure it compiles fine. This will also help with allmodconfig
