From 110afb8b42ea68439b352a87e06563a3a85df6c6 Mon Sep 17 00:00:00 2001 From: Rongjun Ying Date: Tue, 25 Nov 2014 18:46:43 +0800 Subject: [PATCH] ARM: dts: atlas6: Add I2S external clock input pingroup The I2S controller can use the external clock as reference clock with master mode. But based on different hardware or software design, this external clock might be needed or not needed. So the external input pin can be an independent pinctrl group, and the card driver can decice to get it or not.
