From 0605815e7ec21e048febcebb691d7f0cc3bdc36c Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Fri, 14 Nov 2014 15:51:34 +0800 Subject: [PATCH] ASoC: rt5670 : Add ACPI match ID for Intel CHT/BSW platforms This patch adds the ACPI match ID for rt5670/5672 codec. So on Intel CherryTrail/Braswell platforms, the codec can be enumerated from ACPI and depends on ACPI to get platform-specific info and power saving.
