ARM: dts: sun5i: Enable USB DRC on A10s OLinuxIno Micro (24354cc7) · Commits · 戴 / test

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.
