power: regulator: Fix regulator_enable/disable() macros

2026-07-12T08:18:32Z

The commit 076265b75e61 ("compat: regulator: add enable/disable macros") added regulator_enable/disable() macros to provide a closer analogue to the Linux API. These new macros wrap regulator_set_enable() that may return detailed error codes and should typically not directly be called by drivers. Change the macros to wrap regulator_set_enable_if_allowed() that masks error codes consumers typically do not expect to closer match the behavior of the Linux API. Also move the macros outside the #if #else blocks to make the macros available when !CONFIG_IS_ENABLED(DM_REGULATOR).

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.

power: regulator: tps65941: Enable FPWM bits

2026-05-06T02:20:29Z

Depending on the phase selection (single or multi), the FPWM bits configured forces the regulator to operate in PWM mode. In case of multi-phase selection, the FPWM_MP bits enforce the regulator to also operate in multi-phase. This fixes correct multi-phase operation. While at this, correct incorrect macro alignment as well.

Merge patch series "Linux compat improvements and CCF prep"

2026-04-21T17:21:59Z

Casey Connolly says: This series implements various improvements to Linux header compatibility, largely in preparation for a full port of Linux CCF but many of these changes would also be helpful when porting other drivers. Beside the basic header/compat stuff there are a few larger patches: Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the same as it does in Linux printing the name of the ofnode, but notably it expects an ofnode pointer rather than a device_node. Patch 2 adds an option to skip doing a full DM scan pre-relocation. Some platforms like Qualcomm don't actually need devices to be probed prior to relocation, it is also quite slow to scan the entire FDT before caches are up. This option gets us to main loop 30-50% faster. Unfortunately it isn't possible to totally skip DM since U-Boot will panic if it can't find a serial port, but the serial uclass code will bind the serial port itself by reading /chosen/stdout-path, however any dependencies like clocks won't be found so this should only be enabled if the serial driver gracefully handles missing clocks. Patch 3 adds [k]strdup_const(), this works the same as the Linux version saving a small amount of memory by avoiding duplicating strings stored in .rodata, this is particularly useful for CCF. Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions, making it possible to parse 64-bit arrays. Patch 6 provides a simple implementation of kref, this will be used by CCF. Patch 9 adds devm_krealloc() support to devres, it relies on storing allocation sizes in the devres struct which will add a small overhead.

power: regulator: cpcap: remove bit_offset_from_cpcap_lowest_voltage

2026-03-22T12:58:57Z

The bit_offset_from_cpcap_lowest_voltage value was inherited from the downstream kernel as a quirk. With the correct voltage table, it is no longer needed. An additional benefit is that SW1, SW2, and SW4 now share the same voltage table. Signed-off-by: Svyatoslav Ryhel

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.
