From 3c25381f9b3375c326f5ead194cb91b5ac181f08 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Mon, 31 Mar 2014 14:49:55 -0700 Subject: [PATCH] pinctrl: msm: Make number of functions variable The various pins may have different number of functions defined, so make this number definable per pin instead of just increasing it to the largest one for all of the platforms.
