On Odroid c2 previously use gpio-hog to reset the usb hub, switch to used on-board usb hub reset to enable the usb hub and enable power to hub. Signed-off-by: Anand Moon <linux.amoon@gmail.com> --- v2 - drop the vendor name from compatible string. - move the hub node to USB controller node. - drop the usb_otg_pwr since it only liked to OTG port and link p5v0 to the vdd-supply. --- .../boot/dts/amlogic/meson-gxbb-odroidc2.dts | 26 ++++++++----------- 1 file changed, 11 insertions(+), 15 deletions(-)
