From 84394616dffac91bcf94423ed02b2877fc2d270f Mon Sep 17 00:00:00 2001 From: Rizwan Qureshi Date: Thu, 2 Feb 2017 12:23:37 +0530 Subject: 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.
