pinctrl: make the pinmux-pins more helpful (1cf94c45) · Commits · 戴 / test

The debugfs file pinmux-pins used to tell which function was enabled but now states simply which device owns the pin. Being owned by the pinctrl driver itself means just that it's hogged so be a bit more helpful by printing that. ChangeLog v1->v2: - Preserve the self-referential owner field, just clarify that when the pin controller states itself as owner this means that it's hogged. Acked-by:
