Subject: [PATCH v5 03/10] arm: dts: mt7623: add mt6323.dtsi file
From: John Crispin <john@...ozen.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. For
those boards with the same PMIC, the intermediate mt6323.dtsi could be
reused to save more redundant nodes created on each board device-tree
files.
