From b63144e6c6097486e7678f9ecc2769b68d2ec83e Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 4 Jul 2013 08:56:28 +0100 Subject: [PATCH] ASoC: arizona: Add signal activity output for DRC When doing signal activity detection, the only output from the DRC will often be a GPIO pin. This patch adds a signal activity output that is activated when a GPIO is configured to output the DRC signal activity detection.
