[PATCH 5/5] regulator: qcom_rpm-regulator: Add support for pm8018 rpm regulator
From: Neil Armstrong
Date: Fri Jun 17 2016 - 06:22:30 EST
In order to support eh Qualcomm MDM9615 SoC, add support for the
PM8018 RPM regulator in the qcom_rpm-regulator driver.
Signed-off-by: Neil Armstrong <narmstrong@xxxxxxxxxxxx>
