From 2439ea1f0f8f4cc98dfae0d1cd5ba88f6c3ee9ad Mon Sep 17 00:00:00 2001 From: Sven Brandau Date: Wed, 2 Apr 2014 10:25:05 +0200 Subject: ASoC: sta350: Add codec driver The TI STA350 is an integrated 2.1-channel power amplifier that is controllable over I2C. This patch adds an ASoC driver for it. At a glance, this chip is very similar to the STA320 for which a driver already exists. In details, however, the register maps contain subtle differences which made a whole new driver easier to write and maintain.
