commit 555627a8fcc22ff5bec8b16aa45307419ebb4d41 Author: Duncan Laurie dlaurie@chromium.org Date: Tue Jan 31 15:09:02 2017 -0800
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.
BUG=chrome-os-partner:58666 TEST=play test sound in OS over internal speaker
