From: Rongjun Ying Date: Mon, 18 Aug 2014 08:49:24 +0000 (+0800) Subject: pinctrl: atlas6: Add I2S external clock input pingroup X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=086b8904;p=linux-beck.git pinctrl: 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.
