commit 7a90f6ce4b855a0b3d2acfe6095e3247fd55133a Author: Tom Warren twarren@nvidia.com Date: Mon Nov 10 09:29:32 2014 -0700
ryu: audio: Enable RT5677 audio codec
Take codec out of reset (GPIO_PH1 aka CODEC_RST_L) and enable LDO2 (GPIO_PR2/KB_ROW2 aka AUDIO_ENABLE). Muxes are setup and the two GPIOs are set to output and driven high.
BUG=chrome-os-partner:32582 BRANCH=none TEST=RealTek ALC5677 codec shows up in I2C6 scan at address 0x2D, can read/write registers.
