[PATCH 11/12] arm64: dts: r8a7795: salvator-x: add bias setting for usb1_pins

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

 



From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@xxxxxxxxxxx>

Since this board doesn't mount pull-up/down registers for
USB1_{OVC,PWEN} pins, we should enable bias setting to pull these
pins up/down.
