From 3f9bfe0d0e1a0e029d4258f39fbddffd06bf210b Mon Sep 17 00:00:00 2001 From: Jianqun Date: Fri, 12 Sep 2014 18:54:55 +0800 Subject: [PATCH] ARM: dts: add rk3288 i2s controller Add dt for rk3288 i2s controller, since i2s clock pins and data pins default to be GPIO, this patch also add pinctrl to mux them. Tested on RK3288 board.
