2022-08-25regulator: pca9450: Remove restrictions for regulator-nameFrieder Schrempf
commit b0de7fa706506bf0591037908376351beda8c5d6 upstream. The device bindings shouldn't put any constraints on the regulator-name property specified in the generic bindings. This allows using arbitrary and descriptive names for the regulators.

[ Upstream commit 6d435a94ba5bb4f2ad381c0828fbae89c66b50fe ] The MT6315 PMIC dt-binding should enforce that one of the valid regulator-compatible is set in each regulator node.

2021-11-18regulator: s5m8767: do not use reset value as DVS voltage if GPIO DVS is ↵Krzysztof Kozlowski
disabled commit b16bef60a9112b1e6daf3afd16484eb06e7ce792 upstream. The driver and its bindings, before commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") were requiring to provide at least one safe/default voltage for DVS registers if DVS GPIO is not being enabled. IOW, if s5m8767,pmic-buck2-uses-gpio-dvs is missing, the s5m8767,pmic-buck2-dvs-voltage should still be present and contain one voltage. This requirement was coming from driver behavior matching this condition (none of DVS GPIO is enabled): it was always initializing the DVS selector pins to 0 and keeping the DVS enable setting at reset value (enabled). Therefore if none of DVS GPIO is enabled in devicetree, driver was configuring the first DVS voltage for buck[234]. Mentioned commit 04f9f068a619 ("regulator: s5m8767: Modify parsing method of the voltage table of buck2/3/4") broke it because DVS voltage won't be parsed from devicetree if DVS GPIO is not enabled. After the change, driver will configure bucks to use the register reset value as voltage which might have unpleasant effects. Fix this by relaxing the bindings constrain: if DVS GPIO is not enabled in devicetree (therefore DVS voltage is also not parsed), explicitly disable it.

2021-06-21Merge series "Extend regulator notification support" from Matti Vaittinen ↵Mark Brown
<matti.vaittinen@fi.rohmeurope.com>: Extend regulator notification support This series extends the regulator notification and error flag support. Initial discussion on the topic can be found here: https://lore.kernel.org/lkml/6046836e22b8252983f08d5621c35ececb97820d.camel@fi.rohmeurope.com/ In a nutshell - the series adds: 1. WARNING level events/error flags. (Patch 3) Current regulator 'ERROR' event notifications for over/under voltage, over current and over temperature are used to indicate condition where monitored entity is so badly "off" that it actually indicates a hardware error which can not be recovered. The most typical hanling for that is believed to be a (graceful) system-shutdown. Here we add set of 'WARNING' level flags to allow sending notifications to consumers before things are 'that badly off' so that consumer drivers can implement recovery-actions. 2. Device-tree properties for specifying limit values. (Patches 1, 5) Add limits for above mentioned 'ERROR' and 'WARNING' levels (which send notifications to consumers) and also for a 'PROTECTION' level (which will be used to immediately shut-down the regulator(s) W/O informing consumer drivers. Typically implemented by hardware). Property parsing is implemented in regulator core which then calls callback operations for limit setting from the IC drivers. A warning is emitted if protection is requested by device tree but the underlying IC does not support configuring requested protection. 3. Helpers which can be registered by IC. (Patch 4) Target is to avoid implementing IRQ handling and IRQ storm protection in each IC driver. (Many of the ICs implementin these IRQs do not allow masking or acking the IRQ but keep the IRQ asserted for the whole duration of problem keeping the processor in IRQ handling loop). 4. Emergency poweroff function (refactored out of the thermal_core to kernel/reboot.c) which is called if IC fires error IRQs but IC reading fails and given retry-count is exceeded. (Patches 2, 4) Please note that the mutex in the emergency shutdown was replaced by a simple atomic in order to allow call from any context. The helper was attempted to be done so it could be used to implement roughly same logic as is used in qcom-labibb regulator. This means amongst other things a safety shut-down if IC registers are not readable. Using these shut-down retry counters are optional. The idea is that the helper could be also used by simpler ICs which do not provide status register(s) which can be used to check if error is still active. ICs which do not have such status register can simply omit the 'renable' callback (and retry-counts etc) - and helper assumes the situation is Ok and re-enables IRQ after given time period. If problem persists the handler is ran again and another notification is sent - but at least the delay allows processor to avoid IRQ loop. Patch 7 takes this notification support in use at BD9576MUF. Patch 8 is related to MFD change which is not really related to the RFC here. It was added to this series in order to avoid potential conflicts. Patch 9 adds a maintainers entry. Changelog v10-RESEND: - rebased on v5.13-rc4 Changelog v10: - rebased on v5.13-rc2 - Move rdev_*() print macros to the internal.h and use rdev_dbg() from irq_helpers.c - Export rdev_get_name() and move it from coupler.h to driver.h for others to use. (It was already in coupler.h but not exported - usage was limited and coupler.h does not sound like optimal place as rdev_name is not only used by coupled regulators) - Send all regulator notifications from irq_helpers.c at one OR'd event for the sake of simplicity. For BD9576 this does not matter as it has own IRQ for each event case. Header defining events says they may be OR'd. - Change WARN() at protection shutdown to pr_emerg as suggested by Petr. Changelog v9: - rebases on v5.13-rc1 - Update thermal documentation - Fix regulator notification event number Changelog v8: - split shutdown API adding and thermal core taking it in use to own patches. - replace the spinlock with atomic when ensuring the emergency shutdown is only called once.

Support specifying protection/error/warning limits for regulator over current, over temperature and over/under voltage. Most of the PMICs support only "protection" feature but few setups do also support error/warning level indications. On many ICs most of the protection limits can't actually be set. But for example the ampere limit for over-current protection on ROHM BD9576 can be configured - or feature can be completely disabled. Provide limit setting for all protections/errors for the sake of the completeness and do that using own properties for all so that not all users would need to set all levels when only one or few are supported.

Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays.
