From: Marcus Cooper <redacted> Enable the otg/drc usb controller on the Itead Ibox device. Note this board has the otg-vbus connected directly to the 5v-dcc of the board, so there is no vbus0 regulator, nor vbus0-det. Signed-off-by: Marcus Cooper <redacted> --- Changes since v1: - Added comment concerning vbus0 regulator and detection to commit message
Thanks patch looks good to me: Reviewed-by: Hans de Goede <redacted> Regards, Hans
