Can this be done in the USB driver? Then you might be able to use device_get_supply_regulator().
In fact it looks like board_usb_init() should move into a driver.
if (ret) {printf("%s vcc5v0_host init fail! ret %d\n", __func__, ret);goto out;}ret = regulator_set_enable(regulator, true);if (ret) {printf("%s vcc5v0-host enable fail!\n", __func__);goto out;}return 0;+out:
printf("%s board ini error %x\n", __func__, ret);return ret;}
