ARM: dts: sun5i: Enable USB DRC on A10s OLinuxIno Micro
Browse files Browse the repository at this point in the history
Enable the otg/drc usb controller on the A10s OLinuxIno Micro.

Note the A10s OlinuxIno Micro always has some voltage on its otg power
pin, even if the usb-vbus0-regulator is disabled, the leaked voltage is
enough to make vbus-det always report 1, so we do not use vbus-det on
this board.
