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 --------------------------------------------------------------------------------------- regulator-dummy 1 0 0 unknown 0mV 0mA 0mV 0mV dc_in_12v 2 1 0 unknown 12000mV 0mA 12000mV 12000mV vcc_4v 7 10 0 unknown 4000mV 0mA 4000mV 4000mV buck1 1 0 0 unknown 1050mV 0mA 500mV 3425mV buck2 1 0 0 unknown 900mV 0mA 500mV 3425mV buck3 1 0 0 unknown 1800mV 0mA 500mV 1800mV buck4 1 0 0 unknown 3300mV 0mA 500mV 3300mV buck5 3 7 0 unknown 2100mV 0mA 500mV 3425mV dldo1 0 0 0 unknown 1200mV 0mA 500mV 3125mV dldo2 0 0 0 unknown 500mV 0mA 500mV 3125mV dldo3 0 0 0 unknown 500mV 0mA 500mV 3125mV dldo4 1 0 0 unknown 1800mV 0mA 500mV 3125mV dldo5 0 0 0 unknown 500mV 0mA 500mV 3125mV dldo6 1 0 0 unknown 1800mV 0mA 500mV 3125mV dldo7 0 0 0 unknown 500mV 0mA 500mV 3125mV buck6 1 0 0 unknown 1100mV 0mA 500mV 3425mV aldo1 0 0 0 unknown 1800mV 0mA 500mV 3125mV aldo2 0 0 0 unknown 500mV 0mA 500mV 3125mV aldo3 0 0 0 unknown 500mV 0mA 500mV 3125mV aldo4 0 0 0 unknown 500mV 0mA 500mV 3125mV Best regards, Javier Javier Martinez Canillas (3): riscv: dts: spacemit: Enable i2c8 adapter for Milk-V Jupiter riscv: dts: spacemit: Define fixed regulators for Milk-V Jupiter riscv: dts: spacemit: Define the P1 PMIC regulators for Milk-V Jupiter .../boot/dts/spacemit/k1-milkv-jupiter.dts | 135 ++++++++++++++++++ 1 file changed, 135 insertions(+) -- 2.52.0 base-commit: bb3a1f127972ea262f98eee55068de1e54ab8d57 branch: milkv-jupiter-pmic
