regulator: rtq6752: fix reg reset behavior
Reg will be reset in below two conditions.
1. 'Enable' pin from H to L.
2. Both PAVDD and NAVDD are all disabled.

And 'Enable' pin also control i2c communication capability.

This patch is to Seperate the if condition in enable/disable callback for
reg cache manipulation.

regulator: da9063: Add support for full-current mode.
In addition to the ability of merging some power outputs, this chip has
an overdrive mode.
BCORE1, BCORE2 and BPRO have this ability, in which case the legal
current draw is increased from 2 amps to 2.5 amps (at the expense of
a quiescent current increase), and the configurable current limits
are doubled.
If a current higher than maximum half-current mode is requested, enable
overdrive, and scale the current limit down.
Symmetrically, scale the current limit up when querying a overdrive-enabled
regulator.

Merge series "regulator: devres: remove unused device-managed unregister APIs" from Alexandru Ardelean <aardelean@deviqon.com>:
These APIs aren't used anywhere and most-likely exist because of the
general principle of C APIs, where if an API function does an
allocation/registration, it must also have an equivalent
deallocation/deregistration counterpart.

For devm_ functions this isn't all that true (for all cases), as the idea
of these function is to provide an auto-cleanup logic on drivers/system
de-init.

Removing these discourages any weird logic that could be created with
such an API functions.

Merge series "Move Hisilicon 6421v600 SPMI and USB drivers out of staging" from Mauro Carvalho Chehab <mchehab+huawei@kernel.org>:
Hi Greg,

As promised, that's the version 11, meant to be applied after -rc1.

It depends on a regression fix patch merged via the regulator's tree:

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git/commit/?h=for-5.14&id=5db5dd5be70eaf808d9fd90174b957fc5c2912cb

(the dependence is just because of a trivial merge conflict)

This series contain the final bits needed for the USB3 bus to work
without staging drivers on Hikey 970.

The usage of da_vsel_mask is different from other mask defines because

regulator: devres: unexport devm_regulator_unregister_supply_alias()
This API hook isn't used anywhere outside of the regulator devres code.
This function is needed for the devm_regulator_bulk_register_supply_alias()
function on the error path, to cleanup any previously registered supply
aliases.

This change makes the devm_regulator_unregister_supply_alias() local to the
regulator core framework, to avoid it being used in any weird logic.
It's also removing the doc-string for
devm_regulator_unregister_supply_alias(), since it doesn't need to be
documented anymore, as no other external consumer should use it.

regulator: hi6421: Fix getting wrong drvdata
Since config.dev = pdev->dev.parent in current code, so
dev_get_drvdata(rdev->dev.parent) call in hi6421_regulator_enable
returns the drvdata of the mfd device rather than the regulator. Fix it.

This was broken while converting to use simplified DT parsing because the
config.dev changed from pdev->dev to pdev->dev.parent for parsing the
parent's of_node.

Merge series "Extend regulator notification support" from Matti Vaittinen <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.

Changelog v4:
   - rebased on v5.12-rc6
   - dropped RFC
   - fix external FET DT-binding.
   - improve prints for cases when expecting HW failure.
   - styling and typos

Changelog v3:
  Regulator core:
   - Fix dangling pointer access at regulator_irq_helper()
  stpmic1_regulator:
   - fix function prototype (compile error)
  bd9576-regulator:
   - Update over current limits to what was given in new data-sheet
     (REV00K)
   - Allow over-current monitoring without external FET. Set limits to
     values given in data-sheet (REV00K).

Changelog v2:
  Generic:
  - rebase on v5.12-rc2 + BD9576 series
  - Split devm variant of delayed wq to own series
  Regulator framework:
  - Provide non devm variant of IRQ notification helpers
  - shorten dt-property names as suggested by Rob
  - unconditionally call map_event in IRQ handling and require it to be
    populated
  BD9576 regulators:
  - change the FET resistance property to micro-ohms
  - fix voltage computation in OC limit setting

regulator: bd9576: Support error reporting
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).

regulator: move rdev_print helpers to internal.h
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.

- Dedicated power management IC TCS4525
- Lithium battery protection chip TCS4526

This has been tested with a Radxa Rock Pi N10.

regulator: bd718x7: Fix the BUCK7 voltage setting on BD71837
Changing the BD71837 voltages for other regulators except the first 4 BUCKs
should be forbidden when the regulator is enabled. There may be out-of-spec
voltage spikes if the voltage of these "non DVS" bucks is changed when
enabled. This restriction was accidentally removed when the LDO voltage
change was allowed for BD71847. (It was not noticed that the BD71837
BUCK7 used same voltage setting function as LDOs).

Additionally this bug causes incorrect voltage monitoring register access.
The voltage change function accidentally used for bd71837 BUCK7 is
intended to only handle LDO voltage changes. A BD71847 LDO specific
voltage monitoring disabling code gets executed on BD71837 and register
offsets are wrongly calculated as regulator is assumed to be an LDO.

Prevent the BD71837 BUCK7 voltage change when BUCK7 is enabled by using
the correct voltage setting operation.
