From 1bb5ec6a6a0e094c84cc4fa2ba4a6d7cf8e9e8c6 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Tue, 30 Nov 2010 16:00:03 +0200 Subject: [PATCH] ASoC: tpa6130a2: Add stereo DAPM path New DAPM widgets, and paths to enable both channels at the same time (for stereo output). With this path the switch time difference can be avoided between left and right channels. The original DAPM paths can be still used, if only one of TPA's output has been connected to a speaker, but for most of the cases, switching to the stereo path is better.
