From 1cf94c45ca31c0ad563e72b095782346cba26b6c Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 24 Feb 2012 06:53:04 +0100 Subject: pinctrl: make the pinmux-pins more helpful 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.
