Subject: [PATCH v2 2/3] extcon: arizona: Update device tree binding for mic detect configurations
Date: Mon, 14 Dec 2015 10:37:12 +0000	[thread overview]
Message-ID: <1450089433-11398-2-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1450089433-11398-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>

Update the device tree binding documentation to include documentation for
the wlf,micd-configs property that is used to specify the configurations
for headset polarity detection (CTIA / OTMP).
