Subject: [PATCH 0/3] riscv: dts: spacemit: Add PMIC and regulators constraints for Milk-V Jupiter
Date: Sat, 6 Dec 2025 14:44:52 +0100 [thread overview]
Message-ID: <20251206134532.1741648-1-javierm@redhat.com> (raw)
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
