Subject: [PATCH] regulator: arizona-ldo1: Mark as always-on if no LDOENA
Date: Thu, 21 Apr 2016 13:02:02 +0100	[thread overview]
Message-ID: <1461240122-3942-1-git-send-email-rf@opensource.wolfsonmicro.com> (raw)

If we don't have a GPIO for LDOENA it's impossible to turn
the LDO1 regulator off so mark it as always-on.
