From 4e195afdf70f2a2daaa628d4e449a841f09d1b5c Mon Sep 17 00:00:00 2001 From: Gabe Black Date: Mon, 5 Aug 2013 22:15:21 -0700 Subject: [PATCH] exynos5250: Add a pinmux function to set up i2s bus 0 This bus is hooked up on snow and, as it's the only bus hooked up on some other boards, having it available in firmware to test is handy.
