From 630e413dc24da0c2373fd7592aeb0e08cea71cd1 Mon Sep 17 00:00:00 2001 From: Petr Kulhavy Date: Tue, 29 Mar 2016 09:39:35 +0200 Subject: ASoC: tas571x: chip type detection via I2C name The chip selection was relying only on DT. It was not possible to use the driver without DT. This adds the chip type detection from the I2C name, which allows to use the driver from the platform driver without DT.
