A common simplified DT parsing code for regulators was introduced in
commit a0c7b164ad ("regulator: of: Provide simplified DT parsing

While at it also added RK8XX_DESC and RK8XX_DESC_SWITCH macros for the
regulator_desc struct initialization. This just makes the driver more compact.

8c12ad8e91 regulator: pwm: Use pwm_get_args() where appropriate
The PWM framework has clarified the concept of reference PWM config (the
platform dependent config retrieved from the DT or the PWM lookup table)
and real PWM state.

Use pwm_get_args() when the PWM user wants to retrieve this reference
config and not the current state.

This is part of the rework allowing the PWM framework to support
hardware readout and expose real PWM state even when the PWM has just
been requested (before the user calls pwm_config/enable/disable()).

f40d4896bf regulator: axp20x: Fix axp22x ldo_io registration error on cold boot
The maximum supported voltage for ldo_io# is 3.3V, but on cold
boot the selector comes up at 0x1f, which maps to 3.8V.

This causes _regulator_get_voltage() to fail with -EINVAL which
causes regulator registration to fail when constrains are used:

[    1.467788] vcc-touchscreen: failed to get the current voltage(-22)
[    1.474209] axp20x-regulator axp20x-regulator: Failed to register ldo_io1
[    1.483363] axp20x-regulator: probe of axp20x-regulator failed with error -22

This commits makes the axp20x regulator driver accept the 0x1f register
value, fixing this.

The datasheet does not guarantee reliable operation above 3.3V, so on
boards where this regulator is used the regulator-max-microvolt setting
must be 3.3V or less.

45389c4752 regulator: core: Add early supply resolution for regulators
The call to set_machine_constraints() in regulator_register(), will
attempt to get the voltage for the regulator. If a regulator is in
bypass will fail to get the voltage (ie. it's bypass voltage) and
hence register the regulator, because the supply for the regulator has
not been resolved yet.

To fix this, add a call to regulator_resolve_supply() before we call
set_machine_constraints(). If the call to regulator_resolve_supply()
fails, rather than returning an error at this point, allow the
registration of the regulator to continue because for some regulators
resolving the supply at this point may not be necessary and it will be
resolved later as more regulators are added. Furthermore, if the supply
is still not resolved for a bypassed regulator, this will be detected
when we attempt to get the voltage for the regulator and an error will
be propagated at this point.

If a bypassed regulator does not have a supply when we attempt to get
the voltage, rather than returing -EINVAL, return -EPROBE_DEFER instead
to allow the registration of the regulator to be deferred and tried
again later.

Please note that regulator_resolve_supply() will call
regulator_dev_lookup() which may acquire the regulator_list_mutex. To
avoid any deadlocks we cannot hold the regulator_list_mutex when calling
regulator_resolve_supply(). Therefore, rather than holding the lock
around a large portion of the registration code, just hold the lock when
aquiring any GPIOs and setting up supplies because these sections may
add entries to the regulator_map_list and regulator_ena_gpio_list,
respectively.

e0341f1732 regulator: tps65917/palmas: Add bypass "On" value
When commit b554e14506 ("regulator: tps65917/palmas: Add bypass
ops for LDOs with bypass capability") introduced bypass capability
to palmas regulator, it went with the assumption that regulator
regmap helpers just check val against the bypass_mask.

Unfortunately, this ignored the explicit "on" and "off" values when
the register value is masked with bypass_mask in commit ca5d1b3524
("regulator: helpers: Modify helpers enabling multi-bit control").

With the recent commit dd1a571dae ("regulator: helpers: Ensure
bypass register field matches ON value"), this issue gets highlighted
and fails tps65917/palmas based platforms which need regulators/ldos
that have bypass capability.

Introduce the bypass_on value appropriately for tps65917/palmas
regulator.

5aa43599da regulator: max77620: Add support for device specific ramp rate setting
Maxim advertised the ramp rate of the rail with some recommended
design specification like output capacitance of rail should be
2.2uF. This make sure that current change in the rail is within
maximum current limit and hence meet the advertised ramp rate.

If there is variation in design which causes the rail current to
change more that maximum current limit then device applies the
current limit. In this case, ramp rate is different than advertised
ramp rate.

Add device specific settings for ramp rate which need to be configure
on device register when measure ramp rate on platform is deviated from
advertised ramp rate. In this case, all delay time calculation for
voltage change is done with measured ramp rate and device ramp rate
is used for configuring the device register.

If measured ramp rate in the platform is same as advertised ramp rate
then regulator-ramp-delay is used for the device register configuration
and ramp time calculation for voltage change.

dd1a571dae regulator: helpers: Ensure bypass register field matches ON value
When checking bypass state for a regulator, we check to see if any bits
in the bypass mask are set. For most cases this is fine because there is
typically, only a single bit used to determine if the regulator is in
bypass. However, for some regulators, such as LDO6 on AS3722, the bypass
state is indicate by a value rather than a single bit. Therefore, when
checking the bypass state, check that the bypass field matches the ON
value.

c438b9d017 regulator: core: Move registration of regulator device
The public functions to acquire a regulator, such as regulator_get(),
internally look-up the regulator from the list of regulators that have
been registered with the regulator device class. The registration of
a new regulator with the regulator device class happens before the
regulator has been completely setup. Therefore, it is possible that
the regulator could be acquired before it has been setup successfully.
To avoid this move the device registration of the regulator to the end
of the regulator setup and update the error exit path accordingly.

8e5356a736 regulator: core: Clear the supply pointer if enabling fails
During the resolution of a regulator's supply, we may attempt to enable
the supply if the regulator itself is already enabled. If enabling the
supply fails, then we will call _regulator_put() for the supply.
However, the pointer to the supply has not been cleared for the
regulator and this will cause a crash if we then unregister the
regulator and attempt to call regulator_put() a second time for the
supply. Fix this by clearing the supply pointer if enabling the supply
after fails when resolving the supply for a regulator.

7ddede6a58 regulator: core: Don't terminate supply resolution early
The function regulator_register_resolve_supply() is called from the
context of class_for_each_dev() (during the regulator registration) to
resolve any supplies added. regulator_register_resolve_supply() will
return an error if a regulator's supply cannot be resolved and this will
terminate the loop in class_for_each_dev(). This means that we will not
attempt to resolve any other supplies after one has failed. Hence, this
may delay the resolution of other regulator supplies until the failing
one itself can be resolved.

Rather than terminating the loop early, don't return an error code and
keep attempting to resolve any other supplies for regulators that have
been registered.

94be46b9e5 regulator: s2mps11: Set default ramp delay for S2MPS11 LDOs
Driver did not provide default value for ramp delay for LDOs which lead
to warning in dmesg, e.g. on Odroid XU4:

[    1.486076] vdd_ldo9: ramp_delay not set
[    1.506875] vddq_mmc2: ramp_delay not set
[    1.523766] vdd_ldo15: ramp_delay not set
[    1.544702] vdd_sd: ramp_delay not set

The datasheet for all the S2MPS1x family is inconsistent here and does
not specify unambiguously the value of ramp delay for LDO. It mentions
30 mV/us in one timing diagram but then omits it completely in LDO
regulator characteristics table (it is specified for bucks).

However the vendor kernels for Galaxy S5 and Odroid XU3 use values of 12
mV/us or 24 mV/us.

Without the ramp delay value the consumers do not wait for voltage
settle after changing it. Although the proper value of ramp delay for
LDOs is unknown, it seems safer to use at least some value from
reference kernel than to leave it unset.

d2d5437bdf regulator: max8973: add support for junction thermal warning
The driver MAX8973 supports the driver for Maxim PMIC MAX77621.
MAX77621 supports the junction temp warning at 120 degC and
140 degC which is configurable. It generates alert signal when
junction temperature crosses these threshold.

MAX77621 does not support the continuous temp monitoring of
junction temperature. It just report whether junction temperature
crossed the threshold or not.

Add support to
- Configure junction temp warning threshold via DT property
to generate alert when it crosses the threshold.
- Add support to interrupt the host from this device when alert
occurred.
- read the junction temp via thermal framework.
