From 7887ab3a274dc5f1d1d94ca0cd41ae495d01f94f Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 17 Feb 2011 16:35:55 -0800 Subject: ASoC: Allow GPIO jack detection to be configured as a wake source Some systems wish to use jacks as wake sources. Provide a wake flag in the GPIO configuration which causes the driver to enable the IRQ as a wake source.
