    Subject[PATCH v3 1/9] arm: dts: mt7623: add mt7623-mt6323.dtsi file
    Date
    From: John Crispin <john@phrozen.org>

    MediaTek produces various PMICs. Which one is used depends on the actual
    circuit design. Instead of adding the correct PMIC node to every dts file
    we instead add a new intermediate dtsi file which adds the PMIC node.
    Additionally we also add the phandles for the regulators to various nodes.
