Interrupt line can be configured on different hardware in different way,
even inverted. Therefore driver should not enforce specific trigger
type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low
with a requirement of acknowledge from the CPU therefore the edge
falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level
sensitive interrupt is here especially important to avoid races. With
an edge configuration in case if first PMIC signals interrupt followed
shortly after by the RTC, the interrupt might not be yet cleared/acked
thus the second one would not be noticed.

regulator/clock: Convert the s2m and s5m DT bindings to schema
Tagged to allow further bindings to rely on these.
Signed-off-by: Lee Jones <lee.jones@linaro.org>
Hi All,

2. Correct inb-supply description in patch 10/10.
Changes since v2
================
1. Add Rob's tags.
2. Remove "regulator-name" from properties (all regulator dtschema).
3. Move "unevaluatedProperties" higher to make code easier to read (all regulator dtschema).
4. Add ref-type to op-mode property (patch 6: s5m8767 regulators).
Changes since v1
================
1. Drop DTS patches - applied.
2. Fully remove bindings/regulator/samsung,s5m8767.txt .
3. Minor subject reformatting and few typos in text.
Intro
=====
This patchset converts all devicetree bindings of Samsung S2M and S5M
PMIC devices from txt to dtschema.
It includes also two fixes because later conversion depends on it
(contextually).
Merging/dependencies
====================
1. Regulator related binding changes depend on first two commits (the
fixes), because of context.
2. The mfd bindings depend on clock and regulator bindings.
The fixes and bindings changes (patches 1-10) should go via the same
tree. For example regulator or mfd tree.
Another alternative is that regulator patches (1-2, 4-6) go via Mark who
later gives MFD a stable branch/tag to pull. Then the clock and MFD
bindings would go on top via MFD tree. Or any other setup you would like
to have.
Overview of devices
===================
Essentially all Samsung S2M and S5M PMICs are very similar devices. They
provide the same functionality: regulators, RTC, 2 or 3 clocks and main
power management (e.g. power cut to SoC).
The differences are mostly in registers layout and number of regulators.
The drivers are built around one common part, mfd/sec-core.c, and share
some drivers between devices:
1. MFD sec-core for all devices,
1. one clock driver for most of devices,
2. one RTC driver for all devices,
3. three regulator drivers.
The regulator drivers were implementing slightly different features,
therefore one regulator binding for all devices does not make much
sense. However the clock device binding can be shared.
The final dtschema bindings try to implement this - share only the clock
bindings.
Best regards,
Krzysztof

2.30.2
The driver and its bindings, before commit 04f9f068a6 ("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 04f9f068a6 ("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.

Fortunately, there is only one user of the binding that was recently added.
Therefore, let's mark the binding as deprecated to prevent it from being

2.31.1
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()

- 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
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.
