test: dm: pmbus: add a sandbox PMBus chip emulator

2026-07-13T03:24:40Z

Add a UCLASS_I2C_EMUL driver that emulates a PMBus 1.x compliant chip behind the sandbox I2C bus, plus the test.dts wiring and sandbox defconfig that bind it to the generic PMBus regulator (compatible = "pmbus"). This design is a stub only: it lets the follow-up dm unit test drive lib/pmbus.c, the generic regulator and the pmbus CLI command with no real hardware. The emulator models a flat per-command 16-bit register file and the three identification block strings (MFR_ID / MFR_MODEL / MFR_REVISION). READ_IIN and READ_POUT are deliberately left unimplemented (the chip NAKs them) so the telemetry printer's "(not supported)" path is exercised, mirroring a real buck that only calibrates a subset of the sensor classes.

power: regulator: add MPS MPQ8785 PMBus regulator driver

2026-07-13T01:16:57Z

Per-chip UCLASS_REGULATOR driver for the MPS MPQ8785 / MPM3695 / MPM3695-25 / MPM82504 family, layered on the shared pmbus_helper adapter. Runs Linux's mpq8785_identify() VOUT_MODE switch (LINEAR16 vs DIRECT m=64 R=1) at probe time, applies the optional mps,vout-fb-divider-ratio-permille DT property, and walks the documented MPS ADDR_VBOOT windows on MFR_ID failure so a die-revision address shift just works. Publishes the pmbus mps last|clear last|clear force vendor extension subcommands (NVM PROTECTION_LAST read and clear) when CMD_PMBUS is enabled. Adapted from Linux code.

power: regulator: add generic PMBus UCLASS_REGULATOR adapter

2026-07-13T01:16:57Z

PMBus regulators differ in numeric formats and quirks, not in how they are driven. Share that common behaviour as a regulator-uclass adapter so chip drivers and the pmbus CLI do not each reimplement the decode and transport, and add a catch-all driver on compatible = "pmbus" for compliant chips that have no dedicated driver yet. Gated by CONFIG_DM_REGULATOR_PMBUS_HELPER and CONFIG_DM_REGULATOR_PMBUS_GENERIC. Signed-off-by: Vincent Jardin Signed-off-by: Peng Fan

test: dm: regulator: Add regulator_set_value_clamp() tests

2026-07-12T08:18:32Z

Add a sandbox LDO3 with a configurable 1.8V to 3.3V range and use it to test regulator_set_value_clamp(). Test in-range requests, clamping against the regulator limits, invalid ranges outside the regulator limits and a min value higher than max.

power: regulator: Add helper to set voltage within an acceptable range

2026-07-12T08:18:32Z

Add regulator_set_value_clamp() that clamps a requested target voltage to both caller-provided limits and the regulator constraints before setting the regulator voltage value. Return -EINVAL when the caller limits cannot be satisfied by the regulator constraints or when the requested range is invalid. This helper will initially be used to set vqmmc-supply voltage within an acceptable range according to SD Standards, i.e. 1.70V-1.95V and 2.7V-3.6V.
