From 10a3472a83d3be18495d18ed5612394bb6262f58 Mon Sep 17 00:00:00 2001 From: Florian Vaussard Date: Fri, 31 May 2013 14:32:58 +0200 Subject: [PATCH] ARM: dts: OMAP2+: Header file for pinctrl constants Most of the constants are taken from arch/arm/mach-omap2/mux.h. Define some others for the PIN_OUTPUT_* flavours.
