Current code set "config.driver_data = sreg" but sreg only init the mutex, the othere fields are just zero. Fix it by pass *info to config.driver_data so each regulator can get corresponding data by rdev_get_drvdata(). Separate enable_mutex from struct hi6421_spmi_reg_info since only need one mutex for the driver.

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. Changelog v7: general: - rebased on v5.12-rc7 - new patch for refactoring the hw-failure reboot logic out of thermal_core.c for others to use. notification helpers: - fix regulator error_flags query - grammar/typos - do not BUG() but attempt to shut-down the system - use BITS_PER_TYPE() Changelog v6: Add MAINTAINERS entry Changes to IRQ notifiers - move devm functions to drivers/regulator/devres.c - drop irq validity check - use devm_add_action_or_reset() - fix styling issues - fix kerneldocs Changelog v5: - Fix the badly formatted pr_emerg() call.

2021-06-21regulator: bd9576: Support error reportingMatti Vaittinen
BD9573 and BD9576 support set of "protection" interrupts for "fatal" issues. Those lead to SOC reset as PMIC shuts the power outputs. Thus there is no relevant IRQ handling for them. Few "detection" interrupts were added to the BD9576 with the idea that SOC could take some recovery-action before error gets unrecoverable. Add support for over and under voltage detection for Vout1 ... Vout4 and VoutL1. Add over-current detection for VoutS1 and finally a thermal warning (common for all regulators) which alerts 30 C before temperature reaches the thermal shutdown point. This way consumer drivers can build error-recovery mechanisms. Unfortunately the BD9576 interrupt logic was not re-evaluated. IRQs are not designed to be properly acknowleged - and IRQ line is kept active for whole duration of error condition (in comparison to informing only about state change).

2021-06-21regulator: move rdev_print helpers to internal.hMatti Vaittinen
The rdev print helpers are a nice way to print messages related to a specific regulator device. Move them from core.c to internal.h As the rdev print helpers use rdev_get_name() export it from core.c. Also move the declaration from coupler.h to driver.h because the rdev name is not just a coupled regulator property. I guess the main audience for rdev_get_name() will be the regulator core and drivers.

2021-06-08regulator: fan53880: Fix vsel_mask setting for FAN53880_BUCKAxel Lin
According to the datasheet: REGISTER DETAILS − 0x02 BUCK, BUCK_OUT is BIT0 ~ BIT7. So vsel_mask for FAN53880_BUCK should be 0xFF.

2021-06-08regulator: bd71815: Get rid of struct bd71815_pmicAxel Lin
The content of bd71815_regulators is never changed, no need to duplicate it, thus remove descs[BD71815_REGULATOR_CNT]. The *regmap, *dev and *rdev[BD71815_REGULATOR_CNT] are not really needed. The *gps is unused. Thus the struct bd71815_pmic can be removed.

2021-06-08regulator: ltc3589: Convert to use regulator_set_ramp_delay_regmapAxel Lin
Use regulator_set_ramp_delay_regmap instead of open-coded LTC3589_LINEAR_REG() no longer call LTC3589_REG() now. Only LTC3589_LINEAR_REG() needs to set go_bit, thus remove go_bit parameter from LTC3589_REG() macro.

2021-06-07regulator: mt6359: Get rid of linear_range tablesAxel Lin
The MT6359_BUCK and MT6359_LDO_LINEAR macros setup both linear settings (min_uV, uV_step, linear_min_sel) and linar_range (linear_ranges, n_linear_ranges) settings. All the linear range tables actually only has one entry. Let's simplify it by using linear instead of linear range. The linear_min_sel setting is 0 for all cases, remove it from the macros.
