From 857f9dc3f60fba212285eae7b3266559c355a616 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Thu, 22 Jun 2017 22:49:00 +0800 Subject: pinctrl: DT: extend the pinmux property to support integers array Some platforms may need more than one integer to represent a complete pinmux binding, so let's extend the pinmux property to allow to accept integer array instead of only a single integer.
