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

power: regulator: Correct Kconfig for PFUZE100

2026-05-06T02:20:30Z

Use CONFIG_$(PHASE_)DM_REGULATOR_PFUZE100 as the build condition for pfuze100 regulator driver. Add Kconfig option for SPL_DM_REGULATOR_PFUZE100. To avoid break current platforms, set the Kconfig default value same as PMIC_PFUZE100. Signed-off-by: Peng Fan

power: regulator: mt6359: add driver for MT6359P

2026-02-25T07:18:22Z

Add a new regulator driver for MT6359P and similar PMIC chips. The MT6359P is a eco version for MT6359 regulator. For the MT8391 platform, we use the MT6359P (MT6365) as the main PMIC. The MT6359 and MT6359P have different register maps. Therefore, on the MT8391 platform, we only provide support for the MT6359P. If support for the MT6359 PMIC it can be added later.

Added a new regulator driver for the MAXIM MAX8907 PMIC, providing essential regulator functionalities and incorporated the necessary binding framework within the core PMIC driver. Tested-by: Ion Agorria Signed-off-by: Svyatoslav Ryhel

power: regulator: Add a driver for the AXP PMIC drivevbus

2025-04-28T18:45:43Z

AXP PMICs have a pin which can either report the USB VBUS state, or driving a regulator that supplies USB VBUS. Add a regulator driver for controlling this pin. The selection between input and output is done via the x-powers,drive-vbus-en pin on the PMIC (parent) node. Signed-off-by: Samuel Holland Signed-off-by: Andre Przywara Reviewed-by: Jernej Skrabec

Merge patch series "Switch to using $(PHASE_) in Makefiles"

2025-04-11T18:16:49Z

Tom Rini says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit.
