From 03431972ac16bbfcbfb831bb37c419f8f71bf16d Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 4 Nov 2011 17:11:54 +0000 Subject: [PATCH] ASoC: Disable thermal shutdown when not using speakers in wm_hubs The thermal shutdown support in wm_hubs devices is tied to the speaker drivers (which are the only high power subsystems within the device). Ensure minimal current usage when the thermal shutdown support is not required by disabling the circuit when the speaker drivers are powered down.
