[PATCH v2 1/2] PCI: dwc: Add host_post_init() callback

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This callback can be used by the platform drivers to do configuration once
all the devices are scanned. Like changing LNKCTL of all downstream devices
to enable ASPM etc...
