commit 87d9f7911ee8c7021d60982b8d8e5deee4bd3e1b Author: Rizwan Qureshi rizwan.qureshi@intel.com Date: Thu Feb 2 12:23:37 2017 +0530
google/poppy: Set GPIO GPP_D22 high
same change as I49935e659bf67225d3f5db1b06acc2cd046dcd74 this is required for poppy board as well.
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=None BRANCH=None TEST=play test sound in OS over internal speaker
