Subject: [PATCH 28/53] usb: dwc2: Add Amlogic G12A DWC2 Params
|
||
|
|
|
||
|
|
This patchs sets the params for the DWC2 Controller found in the
|
||
|
|
Amlogic G12A SoC family.
|
||
|
|
|
||
|
|
It mainly sets the settings reported incorrect by the driver,
|
||
|
|
leaving the remaining detected automatically by the driver and
|
||
|
|
provided by the DT node.
