Subject: [PATCH] MLK-18794-1 usb: host: xhci: add .bus_suspend override
|
|
|
|
Some platforms (eg: Cadence USB3) have special requirements to add
|
|
platform USB register setting between xhci_bus_suspend and
|
|
platform USB controller suspend routine. Eg, The Cadence USB3 needs
|
|
RX detect clock switch from 24Mhz to 32Khz within 100ms after set
|
|
port to U3, but sometimes, for USB3 HUB connection, the USB2
|
|
bus suspend will cost more than 100ms, and introduce the disconnection
|
|
before the PHY enters low power mode, then the state is in mess from
|
|
controller side.
|
|
|
|
So in this commit, we introduce .bus_suspend for xhci_driver_overrides
|
|
for above use cases.
