Subject: [PATCH RESEND 1/5] mfd: arizona: Add registers for ADC microphone detection
Date: Wed, 9 Sep 2015 09:34:46 +0100 [thread overview]
Message-ID: <1441787690-30148-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
The newer devices support using a software comparison to determine
whether a 3/4 pole jack is present. Add the registers necessary for
this.
