Keerthy e03826d504 regulator: palmas: Correct TPS659038 register definition for REGEN2
The register offset for REGEN2_CTRL in different for TPS659038 chip as when
compared with other Palmas family PMICs. In the case of TPS659038 the wrong
offset pointed to PLLEN_CTRL and was causing a hang. Correcting the same.

Doug Anderson 29d62ec5f8 regulator: core: Fix enable GPIO reference counting
Normally _regulator_do_enable() isn't called on an already-enabled
rdev.  That's because the main caller, _regulator_enable() always
calls _regulator_is_enabled() and only calls _regulator_do_enable() if
the rdev was not already enabled.

However, there is one caller of _regulator_do_enable() that doesn't
check: regulator_suspend_finish().  While we might want to make
regulator_suspend_finish() behave more like _regulator_enable(), it's
probably also a good idea to make _regulator_do_enable() robust if it
is called on an already enabled rdev.

At the moment, _regulator_do_enable() is _not_ robust for already
enabled rdevs if we're using an ena_pin.  Each time
_regulator_do_enable() is called for an rdev using an ena_pin the
reference count of the ena_pin is incremented even if the rdev was
already enabled.  This is not as intended because the ena_pin is for
something else: for keeping track of how many active rdevs there are
sharing the same ena_pin.

Here's how the reference counting works here:

* Each time _regulator_enable() is called we increment
  rdev->use_count, so _regulator_enable() calls need to be balanced
  with _regulator_disable() calls.

* There is no explicit reference counting in _regulator_do_enable()
  which is normally just a warapper around rdev->desc->ops->enable()
  with code for supporting delays.  It's not expected that the
  "ops->enable()" call do reference counting.

* Since regulator_ena_gpio_ctrl() does have reference counting
  (handling the sharing of the pin amongst multiple rdevs), we
  shouldn't call it if the current rdev is already enabled.

Note that as part of this we cleanup (remove) the initting of
ena_gpio_state in regulator_register().  In _regulator_do_enable(),
_regulator_do_disable() and _regulator_is_enabled() is is clear that
ena_gpio_state should be the state of whether this particular rdev has
requested the GPIO be enabled.  regulator_register() was initting it
as the actual state of the pin.

Javier Martinez Canillas 0548bf4f5a regulator: Only enable disabled regulators on resume
The _regulator_do_enable() call ought to be a no-op when called on an
already-enabled regulator.  However, as an optimization
_regulator_enable() doesn't call _regulator_do_enable() on an already
enabled regulator.  That means we never test the case of calling
_regulator_do_enable() during normal usage and there may be hidden
bugs or warnings.  We have seen warnings issued by the tps65090 driver
and bugs when using the GPIO enable pin.

Let's match the same optimization that _regulator_enable() in
regulator_suspend_finish().  That may speed up suspend/resume and also
avoids exposing hidden bugs.

[Use much clearer commit message from Doug Anderson]

Takashi Iwai cde72ccfdd regulator: Fix regression due to NULL constraints check
The commit [39f802d6b6d9: 'regulator: Build sysfs entries with static
attribute groups'] converted the sysfs entry creation to static
attribute groups, but this resulted in a regression due to the NULL
check of rdev->constraints.  At the point where the device is
registered, rdev->constraints isn't set, so the attributes depending
on it are missing.

We may fix it by shuffling the code order in regulator_register(), but
a quicker fix is to just remove this NULL check.  rdev->constraints is
in anyway always set to non-NULL in set_machine_constraints(), thus
the check there is basically superfluous.

The LDOs are documented in the rk808 datasheet to have a soft start

Geert Uytterhoeven 4d9cbff5aa regulator: da9210: Mask all interrupt sources to deassert interrupt line
After boot-up, some events may be set, and cause the da9210 interrupt
line to be asserted. As the da9210 driver doesn't have interrupt support
yet, this causes havoc on systems where the interrupt line is shared
among multiple devices.

This is the case on e.g. r8a7791/koelsch, where the interrupt line is
shared with a da9063 regulator, and the following events are set:

    EVENT_A = 0x00000011 (GPI0 | GPI4)
    EVENT_B = 0x00000002 (NPWRGOOD)

When drivers use simplified DT parsing method (they provide
'regulator_desc.of_match') they still may want to parse custom
properties for some of the regulators. For example some of the
regulators support GPIO enable control.

Add a driver-supplied callback for such case. This way the regulator
core parses common bindings offloading a lot of code from drivers and
still custom properties may be used.

The callback, called for each parsed regulator, may modify the
'regulator_config' initially passed to regulator_register().

Ashay Jaiswal 83b0302d34 regulator: core: fix race condition in regulator_put()
The regulator framework maintains a list of consumer regulators
for a regulator device and protects it from concurrent access using
the regulator device's mutex lock.

In the case of regulator_put() the consumer is removed and regulator
device's parameters are updated without holding the regulator device's
mutex. This would lead to a race condition between the regulator_put()
and any function which traverses the consumer list or modifies regulator
device's parameters.
Fix this race condition by holding the regulator device's mutex in case
of regulator_put.

Krzysztof Kozlowski 4604a061e6 regulator: tps65023: Constify struct regmap_config and regulator_ops
The regmap_config struct may be const because it is not modified by
the driver and regmap_init() accepts pointer to const. Make struct
regulator_ops const as well.

Linus Torvalds 034496f40d regulator: Fix for v3.19
One fix here, a fix for the voltage mapping on one of the s2mps11
 regulators which broke systems using it including apparently the Gear 2
 smartwatches.

Aniroop Mathur 72dca06f62 regulator: core: Avoid negative regulator no & initialize it to -1
This patch initializes regulator_no to -1 to avoid extra subtraction
operation performed every time we register a regulator and avoid negative
regulator no in its name.

Arnaud Ebalard 6fd753572c regulator: isl9305: deprecate use of isl in compatible string for isil
"isil" and "isl" prefixes are used at various locations inside the kernel
to reference Intersil corporation. This patch is part of a series fixing
those locations were "isl" is used in compatible strings to use the now
expected "isil" prefix instead (NASDAQ symbol for Intersil and most used
version). The old compatible string is kept for backward compatibility.

That will be used regulation_of_get_init_data function for get regulator
