From 5427b0d2bf8865abf5df46d7736cd60a0dc5f9d8 Mon Sep 17 00:00:00 2001 From: Rongjun Ying Date: Tue, 25 Nov 2014 18:46:42 +0800 Subject: ARM: dts: atlas6: add a separate pingroup for i2s mclk output The I2S controller can output mclk to external audio codec. But by hardware design, some codecs need mclk and some codecs do not need mclk. So the mclk pin can be an independent pinctrl group, and the card driver can get it or not based on boards.
