From 4476159f0b73e58e8c4d750ce03843d70c13994c Mon Sep 17 00:00:00 2001 From: Jianqun Date: Sat, 1 Nov 2014 11:22:18 +0800 Subject: [PATCH] ASoC: simple-card: add "invert" property for detect GPIOs Since hardware may invert detect GPIO of headphone or mic, add one property to support software invert.
