From c0eae6112f9c5449b312d6768b618b9f7fde23c9 Mon Sep 17 00:00:00 2001 From: Vaibhav Shankar Date: Mon, 16 Jan 2017 14:54:29 -0800 Subject: mainboard/google/reef: Ignore Audio DMIC IOSSTATE Audio DMIC PLL needs to be ON in S0ix to support Wake on Voice. This requires GPIO_79 and GPIO_80 to be configured as IGNORE IOSSTATE. So DMIC CLKs will be ON in S0ix.
