From 54862bf00968427cf8f7ffcb6dacf03161eae862 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 16 Dec 2011 15:12:31 -0700 Subject: [PATCH] arm/tegra: Refactor board-*-pinmux.c to share code This moves the implementation of *_pinmux_init() into a single location. The board-specific pinmux data is left in each board's own file. This will allow future changes that set up the pinmux in a more complex fashion to do so without duplicating that code in each board's pinmux file.
