The Bananapi M3 and Cubietruck Plus both have USB OTG ports wired to the SoC and PMIC in the same way, with the N_VBUSEN pin on the PMIC controlling VBUS output, the PMIC's VBUS input for sensing VBUS, and PH11 on the SoC for sensing the ID pin. Enable OTG on both boards. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
