12description: |
13  Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
14  definition for each of these nodes is defined using the standard
15  binding for regulators at
16  Documentation/devicetree/bindings/regulator/regulator.txt.
17  Datasheet is available at
18  https://www.nxp.com/docs/en/data-sheet/PCA9450DS.pdf

20#The valid names for PCA9450 regulator nodes are:
21#BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6,
22#LDO1, LDO2, LDO3, LDO4, LDO5
23#Note: Buck3 removed on PCA9450B and connect with Buck1 on PCA9450C.
