Add usb otg support for orangepi-zero-plus2 board: - Add usb_otg node with dr_mode as 'otg' - USB0-IDDET connected to PA21 - VBUS connected through DCIN which always on
Tested mass storage function. Signed-off-by: Jagan Teki <ja...@amarulasolutions.com> --- Note: Anyone please check vbus connection [1] Since it is connected through DCIN of vcc-5v, I've added vcc-5v0 regulator for the same and attached to usb0_vbus-supply but it is disabling during kernel boot.
