From 5de37d5d7a2d9c8a7292655695d487e14e02a45a Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Tue, 31 Jan 2017 15:09:02 -0800 Subject: [PATCH] google/eve: Set GPIO GPP_D22 high GPIO GPP_D22 controls the I2S buffer for isolating the I2S signals when doing GPIO-driven I2S. This needs to be high by default so the DSP can drive these signals, instead of low where it is enabled for GPIO-driven I2S and the DSP cannot drive these signals.
