From ed36c1a06fc73cab289f66cc60b935951f4a1fa0 Mon Sep 17 00:00:00 2001 From: Rongjun Ying Date: Mon, 18 Aug 2014 16:49:22 +0800 Subject: [PATCH] pinctrl: atlas6: take mclk pin out of i2s pingroup 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.
