Subject: [PATCH v2 6/9] regulator: arizona-ldo1: Add additional supported voltage
Date: Fri, 17 Apr 2015 09:42:23 +0100	[thread overview]
Message-ID: <1429260146-16694-7-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1429260146-16694-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>

This patch adds support for the 1.175V mode on the LDO1 regulator on the
wm5110. This is need as part of the low power sleep mode operation.
