Subject: [PATCH 5/8] pinctrl: qcom: spmi-mpp: Add support for setting analog output level
Date: Wed, 17 Jun 2015 23:47:29 -0700	[thread overview]
Message-ID: <1434610052-602-6-git-send-email-bjorn.andersson@sonymobile.com> (raw)
In-Reply-To: <1434610052-602-1-git-send-email-bjorn.andersson@sonymobile.com>

When the MPP is configured for analog output the output level is selected by
the AOUT_CTL register, this patch makes it possible to control this.
