From 304f5784e97281f18ef4bed574cbe5fcf6ce2f2e Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andr=C3=A9=20Draszik?= Date: Fri, 9 Jan 2026 08:38:43 +0000 Subject: regulator: core: reresolve unresolved supplies when available MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When a regulator A and its supply B are provided by different devices, the driver implementing B might be last to probe (with A still pending resolution of its supply B). While we try to resolve all pending supplies for all regulators (including A) during regulator_register() of B via regulator_register_resolve_supply(), supply resolution will still not work for A as the driver for B hasn't finished binding to the PMIC device corresponding to B at that stage yet. The regulator core explicitly only allows supplies from other devices to be used once the relevant driver has fully bound, mainly to avoid having to deal with cases where B itself might -EPROBE_DEFER. In this case, A's supply will only be resolved as part of the core's regulator_init_complete_work_function(), which currently is scheduled to run after 30s. This was added as a work-around in commit 3827b64dba27 ("regulator: core: Resolve supplies before disabling unused regulators") to cover this situation. There are two problems with that approach: * it potentially runs long after all our consumers have probed * an upcoming change will allow regulator_register() to complete successfully even when required supplies (e.g. due to always-on or boot-on) are missing at register time, deferring full configuration of the regulator (and usability by consumers, i.e. usually consumer probe) until the supply becomes available. Resolving supplies in the late work func can therefore make it impossible for consumers to probe at all, as the driver core will not know to reprobe consumers when supplies have resolved. We could schedule an earlier work to try to resolve supplies sooner, but that'd be racy as consumers of A might try to probe before A's supply gets fully resolved via this extra work. Instead, add a very simple regulator bus and add a dummy device with a corresponding driver to it for each regulator that is missing its supply during regulator_register(). This way, the driver core will call our bus' probe whenever a new (regulator) device was successfully bound, allowing us to retry resolving the supply during (our bus) probe and to bind this dummy device if successful. In turn this means the driver core will see a newly bound device and retry probing of all pending consumers, if any. With that in place, we can avoid walking the full list of all known regulators to try resolve missing supplies during regulator_register(), as the driver core will invoke the bus probe for regulators that are still pending their supplies. We can also drop the code trying to resolve supplies one last time before unused regulators get disabled, as all supplies should have resolved at that point in time, and if they haven't then there's no point in trying again, as the outcome won't change. Note: We can not reuse the existing struct device created for each rail, as a device can not be part of a class and a bus simultaneously.

In some hardware designs, multiple PMICs are used where individual rails of each act as supplies for rails of the other, and vice-versa. In such a design no PMIC driver can probe when registering one top- level regulator device (as is common practice for almost all regulator drivers in Linux) since that commit. Supplies are only considered when their driver has fully bound, but because in a design like the above two drivers / devices depend on each other, neither will have fully bound while the other probes. The Google Pixel 6 and 6 Pro (oriole and raven) are examples of such a design. One way to make this work would be to register each rail as an individual device, rather than just one top-level regulator device. Then, fw-devlink and Linux' driver core could do their usual handling of deferred device probe as each rail would be probed individually. This approach was dismissed in [1] as each regulator driver would have to take care of this itself. Alternatively, we can change the regulator core to not fail regulator_register() if a rail's required supply can not be resolved while keeping the intended change from above mentioned commit, and instead retry whenever a new rail is registered. This commit implements such an approach: If set_machine_constraints() requests probe deferral, regulator_register() still succeeds and we retry setting constraints as part of regulator_resolve_supply(). We still do not enable the regulator or allow consumers to use it until constraints have been set (including resolution of the supply) to prevent enabling of a regulator before its supply. With this change, we keep track of regulators with missing required supplies and can therefore try to resolve them again and try to set the constraints again once more regulators become available. Care has to be taken to not allow consumers to use regulators that haven't had their constraints set yet. regulator_get() ensures that and now returns -EPROBE_DEFER in that case. The implementation is straight-forward, thanks to our newly introduced regulator-bus. Locking in regulator_resolve_supply() has to be done carefully, as a combination of regulator_(un)lock_two() and regulator_(un)lock_dependent() is needed. The reason is that set_machine_constraints() might call regulator_enable() which needs rdev and all its dependents locked, but everything else requires to only have rdev and its supply locked.

It typically complements an S2MPG10 PMIC in a main/sub configuration as the sub-PMIC. Like S2MPG10, communication is not via I2C, but via the Samsung ACPM firmware. While at it, we can also switch to asynchronous probe, which helps with probe performance, as the drivers for s2mpg10 and s2mpg11 can probe in parallel. Note: The firmware uses the ACPM channel ID and the Speedy channel ID to select the PMIC address. Since these are firmware properties, they can not be retrieved from DT, but instead are deducted from the compatible for now.

REGULATOR_LINEAR_VRANGE macro MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit REGULATOR_LINEAR_VRANGE is similar to REGULATOR_LINEAR_RANGE, but allows a more natural declaration of a voltage range for a regulator, in that it expects the minimum and maximum values as voltages rather than as selectors. Using voltages arguably makes this macro easier to use by drivers and code using it can become easier to read compared to REGULATOR_LINEAR_RANGE.

It has 10 buck and 31 LDO rails. Several of these can either be controlled via software (register writes) or via external signals, in particular by: * one out of several input pins connected to a main processor's: * GPIO pins * other pins that are e.g. firmware- or power-domain-controlled without explicit driver intervention * a combination of input pins and register writes. Control via input pins allows PMIC rails to be controlled by firmware, e.g. during standby/suspend, or as part of power domain handling where otherwise that would not be possible. Additionally toggling a pin is faster than register writes, and it also allows the PMIC to ensure that any necessary timing requirements between rails are respected automatically if multiple rails are to be enabled or disabled quasi simultaneously. This commit implements support for all these rails and control combinations. Additional data needs to be stored for each regulator, e.g. the input pin for external control, or a rail-specific ramp-rate for when enabling a buck-rail. Therefore, probe() is updated slightly to make that possible. Note1: For an externally controlled rail, the regulator_ops provide an empty ::enable() and no ::disable() implementations, even though Linux can not enable the rail and one might think ::enable could be NULL. Without ops->enable(), the regulator core will assume enabling such a rail failed, though, and in turn never add a reference to its parent (supplier) rail. Once a different (Linux-controlled) sibling (consumer) rail on that same parent rail gets disabled, the parent gets disabled (cutting power to the externally controlled rail although it should stay on), and the system will misbehave. Note2: While external control via input pins appears to exist on other versions of this PMIC, there is more flexibility in this version, in particular there is a selection of input pins to choose from for each rail (which must therefore be configured accordingly if in use), whereas other versions don't have this flexibility.
