Subject: [PATCH 3/7] riscv: dts: spacemit: Define the P1 PMIC regulators for OrangePi RV2
Define the SpacemiT P1 PMIC voltage regulators and their constraints.
The power management hardware design on the OrangePi RV2 is identical to
the Banana Pi BPI-F3, so the DT Nodes were taken from k1-bananapi-f3.dts.
