Subject: ARM: dts: sun5i: Enable USB DRC on A10s OLinuxIno Micro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24354cc7c2b1187ab66ee27dd891bf0d59a8624e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: sun5i: Enable USB DRC on A10s OLinuxIno Micro

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.
