In case of usb-c-connector with power delivery support, add bingdings supported by current typec driver, so user can pass all those properties via dt. Signed-off-by: Li Jun <jun.li@xxxxxxx> --- Changes for v2: - Added typec properties are based on general usb connector bindings[1] proposed by Andrzej Hajda. - Use the standard unit suffixes as defined in property-units.txt.
