+ pf8x00 are a 12-chanel regulator PMIC family. Regulators nodes should
+ be named to ldo<>, sw<> and vnss. The definition for each of these nodes
+ is defined using the standard binding for regulators at
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+ Datasheet is available at https://www.nxp.com/docs/en/data-sheet/PF8100_PF8200.pdf
