The delay is unnecessary. Upstream Linux does not add this delay after
the core soft reset and the USB works fine without it.
Tested in QCS6490 RB3Gen2 Qualcomm board.
The reverted commit states this:
"
Without this delay, USB initialization can fail on some Qualcomm
platforms, particularly when using super-speed capable PHYs like
the QMP USB3-DP Combo PHY on SC7280/QCM6490.
Taken from Linux commit f88359e1588b ("usb: dwc3: core: Do core
softreset when switch mode")
"
Can you test this on one of those two listed devices ?
