From 3dac1918a4912cea9375e76cb3916b751cef22db Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Sat, 6 Sep 2014 18:25:04 +0200 Subject: [PATCH] pinctrl: imx: detect uninitialized pins The pinctrl driver initialized the register offsets for the pins with 0. On Vybrid an offset of 0 is a valid offset for the pinctrl mux register. So far, this was solved using the ZERO_OFFSET_VALID flag which allowed offsets of 0. However, this does not allow to verify whether a pins struct imx_pmx_func was initialized or not. Use signed offset values for register offsets and initialize those with -1 in order to detect uninitialized offset values reliable.
