Subject: [PATCH 37/38] usb: dwc3: register qca,ipq4019-dwc3 in dwc3-of-simple
|
|
||||||
|
|
||||||
For host mode, the dwc3 found in the IPQ4019 can be driven
|
|
||||||
by the dwc3-of-simple module. It will get more tricky for
|
|
||||||
OTG since they'll need to enable VBUS and reconfigure the
|
|
||||||
registers.
