This patch series adds support for RTQ2208 SubPMIC regulators.
The RTQ2208 is a multi-phase, programmable power management IC that
integrate with dual multi-configurable, synchronous buck converters
and two ldos. The bucks features wide output voltage range from 0.4V to 2.05V
and the capability to configure the corresponding power stages.
The previous version of this driver included wildcards in file names and
descriptions. This patch renames the driver to only support MAX5970 and
MAX5978, which are the only chips that the driver actually supports.

This patch series aims to add support for Renesas PMIC RAA215300 and
built-in RTC found on this PMIC device.
The details of PMIC can be found here[1].
Renesas PMIC RAA215300 exposes two separate i2c devices, one for the main
device and another for rtc device.
The RAA215300 is a 9-channel PMIC that consists of
* Internally compensated regulators
* built-in Real Time Clock (RTC)
* 32kHz crystal oscillator
* coin cell battery charger
The RTC on RAA215300 is similar to the IP found in the ISL1208.
The existing driver for the ISL1208 works for this PMIC too,
however the RAA215300 exposes two devices via I2C, one for the RTC
IP, and one for everything else. The RTC IP has to be enabled
by the other I2C device, therefore this driver is necessary to get
the RTC to work.
The external oscillator bit is inverted on PMIC version 0x11.
Add PMIC RAA215300 driver for enabling RTC block and instantiating
RTC device based on PMIC version.

The TPS68470 PMIC provides Clocks, GPIOs and Regulators. At present in
the kernel the Regulators and Clocks are controlled by an OpRegion
driver designed to work with power control methods defined in ACPI, but
some platforms lack those methods, meaning drivers need to be able to
consume the resources of these chips through the usual frameworks.
This commit adds a driver for the regulators provided by the tps68470,
and is designed to bind to the platform_device registered by the
intel_skl_int3472 module.
This is based on this out of tree driver written by Intel:

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
Provide helper function for IC's implementing regulator notifications
when an IRQ fires. The helper also works for IRQs which can not be acked.
Helper can be set to disable the IRQ at handler and then re-enabling it
on delayed work later. The helper also adds regulator_get_error_flags()
errors in cache for the duration of IRQ disabling.

The MT6359 is a regulator found on boards based on MediaTek MT6779 and
probably other SoCs. It is a so called pmic and connects as a slave to
SoC using SPI, wrapped inside the pmic-wrapper.

The only known BD70528 use-cases are such that the PMIC is controlled
from separate MCU which is not running Linux. I am not aware of
any Linux driver users. Furthermore, it seems there is no demand for
this IC. Let's ease the maintenance burden and drop the driver. We can
always add it back if there is sudden need for it.

Support voltage control for regulators on ROHM BD71815 PMIC.
ROHM BD71815 contains 5 bucks, 7 LDOs and a boost (intended for LED).
Bucks 1 and 2 support HW state based voltage level and enable states. Other
regulators support HW state based enable states. All bucks and LDOs 1-5
allow voltage changes for RUN state and LDO4 can be enabled/disabled via
GPIO.
LDO3 does support changing between two predetermined voltages by using
a GPIO but this functionality is not included in this commit.
This work is derived from driver originally written by Tony Luo
<luofc@embedinfo.com> - although not much of original work is left.
