Add bingdings supported by current typec driver, so user can pass all those properties via dt. Signed-off-by: Li Jun <jun.li@xxxxxxx> --- Change for v3: - port-type change to be power-type which only for power. - add data-type for data capability. - preferred-role change to try-power-role(bool property need 2, and user may add both at the same time, so still use one property but rename it to be try-power-role). - Separate basic typec and power delivery properties. - keep the max-sink-mv/ma/mw, and op-mw, because the counterpart driver code is to be back[1], to be discussed if we need those 4 setting for long term.
