power: regulator: add MT6358 driver with MT6366 support

2026-08-24T23:17:38Z

Add a new driver for MediaTek MT6366 PMIC regulators. The register layout is compatible with MT6358, so the driver itself is called "mt6358". Only support for MT6366 is added currently for use with the MediaTek Genio 360 EVK.

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.
