Subject: [PATCH 04/90] ARM: dts: sun6i: mixtile-loftq: Add USB1 VBUS regulator
|
|
|
|
This board is configured with CONFIG_USB1_VBUS_PIN="PH24", but no
|
|
regulator exists in its device tree. Add the regulator, so USB will
|
|
continue to work when the PHY driver switches to using the regulator
|
|
uclass instead of a GPIO.
|
|
|
|
Update the device tree here because it does not exist in Linux.
