From af48f1d08a5474184da9aaf8b77f4a2848b1875e Mon Sep 17 00:00:00 2001 From: Oder Chiou Date: Mon, 6 Oct 2014 16:30:51 +0800 Subject: ASoC: rt5677: Support DSP function for VAD application The ALC5677 has a programmable DSP, and there is a SPI that is dadicated for DSP firmware loading. Therefore, the patch includes a SPI driver for writing the DSP firmware. The VAD(Voice Activaty Detection) has be implemented and use the DSP to recognize the key phase.
