    Subject[PATCH 30/41] arm64: dts: qcom: sdm630-xperia-nile: Add all RPM and fixed regulators
    Date
    From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>

    Add all of the RPM PM660/PM660L regulators and the fixed ones,
    defining the common electrical part of this platform.
