From 45eebda7b4a73deb268b0cbcde06b603a2ba46a2 Mon Sep 17 00:00:00 2001 From: Vitaliy Kulikov Date: Tue, 26 Jul 2011 16:56:20 -0500 Subject: ALSA: hda - Add support for vref-out based mute LED control on IDT codecs This patch also registers all necessary callbacks to support mute LED only when such control is enabled. And it keeps codec AFG in D0 or D1 state all the time when aggressive power managemnt is enabled for vref-out control (and mute LED) work correctly.
