Subject: ARM: dts: sun4i: Enable USB DRC on the Cubieboard
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c68d23ce258ce5ffaa5ef7bba79ced4e6e1b5421;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: sun4i: Enable USB DRC on the Cubieboard

Enable the otg/drc usb controller on the Cubieboard. Note that the
5V of the otg is directly connected to the general 5V, so we only use
the id pin.
