Both of those are however specified with RK_PA2 as the GPIO enabling them, causing the following error when booting: rockchip-pinctrl pinctrl: pin gpio0-2 already requested by vcc-host-5v-regulator; cannot claim for vcc-host1-5v-regulator rockchip-pinctrl pinctrl: pin-2 (vcc-host1-5v-regulator) status -22 rockchip-pinctrl pinctrl: could not request pin 2 (gpio0-2) from group usb20-host-drv on device rockchip-pinctrl reg-fixed-voltage vcc-host1-5v-regulator: Error applying setting, reverse things back Looking at the schematic, there are in fact three USB regulators, vcc_host_5v, vcc_host1_5v and vcc_otg_v5. But the enable signal for all three is driven by Q2604 which is in turn driven by GPIO_A2/PA2. Since these three regulators are not controllable separately, I removed the second one which was causing the error and added labels for all rails to the single regulator.
