From 0809d3dcc0dd8f597adbcd4d881063eb1b437987 Mon Sep 17 00:00:00 2001 From: André Draszik Date: Thu, 22 Jan 2026 15:43:38 +0000 Subject: regulator: s2mps11: drop two needless variable initialisations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The initialisations being removed are needless, as both variables are being assigned values unconditionally further down. Additionally, doing this eager init here might lead to preventing the compiler from issuing a warning if a future code change actually forgets to assign a useful value in some code path.

This currently doesn't work, because the code here currently points the regulator core at each individual regulator sub-node, and therefore the regulator core is unable to find the -supply properties. Update the code to simply let the regulator core handle all the parsing by adding the ::of_match and ::regulators_node members to all existing regulator descriptions, by adding ::of_parse_cb() to those regulators which support the vendor-specific samsung,ext-control-gpios to parse it (S2MPS14), and by dropping the explicit call to of_regulator_match(). Configuring the PMIC to respect the external control GPIOs via s2mps14_pmic_enable_ext_control() is left outside ::of_parse_cb() because the regulator core ignores errors other than -EPROBE_DEFER from that callback, while the code currently fails probe on register write errors and I believe it should stay that way. The driver can now avoid the devm_gpiod_unhinge() dance due to simpler error handling of GPIO descriptor acquisition. This change also has the advantage of reducing runtime memory consumption by quite a bit as the driver doesn't need to allocate a 'struct of_regulator_match' and a 'struct gpio_desc *' for each regulator for all PMICs as the regulator core does that. This saves 40+8 bytes on arm64 for each individual regulator on all supported PMICs (even on non-S2MPS14 due to currently unnecessarily allocating the extra memory unconditionally). With the upcoming S2MPG10 and S2MPG11 support, this amounts to 1640+328 and 1120+224 bytes respectively.

charset=UTF-8 Content-Transfer-Encoding: 8bit Refactor s2mps14_pmic_enable_ext_control() and s2mps11_of_parse_cb() slightly as a preparation for adding S2MPG10 and S2MPG11 support, as both of those PMICs also support control of rails via GPIOs. This also includes the following to avoid further updates in follow-up commits: * On S2MPG10 and S2MPG11, external rail control can be via GPIO or via non-GPIO signals, hence passing a GPIO is allowed to be optional. This avoids inappropriate verbose driver messages. * Prepare to allow use of standard DT property name 'enable-gpios' for newer platforms instead of vendor-specific 'samsung,ext-control'.

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.

It typically complements an S2MPG10 PMIC in a main/sub configuration as the sub-PMIC. It has 12 buck, 1 buck-boost, and 15 LDO rails. Several of these can either be controlled via software (register writes) or via external signals, in particular by: * 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 combination. 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.
