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.

dm: regulator: fix missing quote in error message

power: regulator: Fix incorrect use of binary and

2025-09-24T16:04:02Z

In regulator_list_autoset there is a test for ret being non-zero and error being zero but it uses the binary '&' instead of the logical '&&' which could well lead to unexpected results. Correct this to use the logical '&&' instead. This issue found by Smatch. Signed-off-by: Andrew Goodbody Reviewed-by: Peng Fan Signed-off-by: Peng Fan

power: regulator: Drop regulators_enable_boot_on/off()

power: regulator: Convert regulators_enable_boot_on/off() to regulator_post_probe

2024-10-01T01:19:07Z

Turn regulators_enable_boot_on() and regulators_enable_boot_off() into empty functions. Implement matching functionality in regulator_post_probe() instead. The regulator_post_probe() is called for all regulators after they probe, and regulators that have regulator-always-on or regulator-boot-on DT properties now always probe due to DM_FLAG_PROBE_AFTER_BIND being set on such regulators in regulator_post_bind(). Finally, fold regulator_unset() functionality into regulator_autoset(). Signed-off-by: Marek Vasut

power: regulator: Trigger probe of regulators which are always-on or boot-on

2024-10-01T01:19:07Z

In case a regulator DT node contains regulator-always-on or regulator-boot-on property, make sure the regulator gets correctly configured by U-Boot on start up. Unconditionally probe such regulator drivers. This is a preparatory patch for introduction of .regulator_post_probe() which would trigger the regulator configuration. Parsing of regulator-always-on and regulator-boot-on DT property has been moved to regulator_post_bind() as the information is required early, the rest of the DT parsing has been kept in regulator_pre_probe() to avoid slowing down the boot process.
