From 385a4c2e286571ba824ee5312f506f198866c3b5 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 14 Nov 2012 18:28:39 +0800 Subject: ASoC: ak4104: add reset line property to DT bindings This device doesn't have a pdata definition for legacy boards, and unless anyone need to control the reset GPIO, it's not worth adding one. So this feature is only available to DT users for now.
