Subject: arm: dts: imx8mm-venice-gw700x: fix mp5416 pmic config
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=cd7f37666a79d7cc7eaad9815e70568d64ef3115;p=u-boot.git

arm: dts: imx8mm-venice-gw700x: fix mp5416 pmic config

Fix various MP5416 PMIC configurations:
 - Update regulator names per dt-bindings
 - ensure values fit among valid register values
 - add required regulator-max-microamp property
 - add regulator-always-on prop
