[PATCH RFC 2/4] pinctrl: Rename mux group to group_or_pin to prepare for pin support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxxxxxxxx>

To prepare for adding support for muxing individual pins rename the
group member of the pinctrl_map_mux and pinctrl_setting_mux structs to
group_or_pin.
