Subject: [PATCH 1/9] mfd: arizona: Add registers for ADC microphone detection
Date: Wed, 16 Sep 2015 10:42:13 +0100 [thread overview]
Message-ID: <1442396541-7145-2-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1442396541-7145-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>
The newer devices support using a software comparison to determine
whether a 3/4 pole jack is present. Add the registers necessary for
this.
