[PATCH 0/3] riscv: dts: spacemit: Add PMIC and regulators constraints for Milk-V Jupiter

[Javier Martinez Canillas]

Hello,

This patch series enables the i2c8 adapter, the PMIC, and voltage regulators
for the Milk-V Jupiter board.

The power management hardware design on the Milk-V Jupiter is identical to the
Banana Pi BPI-F3, so the DT Nodes were copied from the k1-bananapi-f3.dts file.

I have verified the I2C address and regulator constraints against the vendor's
downstream DTS to ensure accuracy. I have also dumped the regulator_summary
debugfs entry to check that the regulators and constraints are registered:

$ cat /sys/kernel/debug/regulator/regulator_summary
 regulator                      use open bypass  opmode voltage current     min     max
