Axel Lin f6442aa0b5 regulator: tps65910: Remove unused min_uV and max_uV from struct tps_info
The min_uV and max_uV fields of struct tps_info are not used in the code.
For the case voltage_table is provided, the min_uV and max_uV are the same
values as volt_table[0] and volt_table[n_voltages -1].
For the case voltage_table is not available, having the min_uV and max_uV seems
misleading. Current code uses equations to get the voltage value in this case,
but these equations do not use the min_uV and max_uV fields of struct tps_info.

Thus this patch removes the min_uV and max_uV fields from struct tps_info.

Guennadi Liakhovetski dfad84aeab regulator: support multiple dummy fixed regulators
Currently regulator_register_fixed() uses a constant name to register a
fixed dummy regulator. This is sufficient in principle, since there is no
reason to register multiple such regulators. The user can simply supply all
consumers in one array and use it to initialise such a regulator. However,
in some cases it can be convenient to register multiple such regulators.
This is also a prerequisite for the upcoming patch, that will add a voltage
parameter to this function. The original function is provided as a wrapper
macro.

Sangbeom Kim c848bc8538 regulator: s5m8767a: Support AP watchdog reset operation
The S5M8767A can't know status of ap reset.
So, After AP watchdog reset, AP can't boot normally.

Problem can be happened like below condition.
- AP Bootable lowest voltage(vdd_arm): 0.9v
- AP DVFS voltage table: 0.8v, 0.9v, 1.0v
- During AP works on lowest voltage(0.8V), watchdog reset is asserted
- AP can't boot, because vdd arm is still 0.8v

Solution
- Basic concept:
  After ap watchdog reset, GPIO configuration is changed by default value
- S5M8767A has function of voltage control with gpio (8 levels with 3 gpios)
- Set bootable voltage on level 0 -> can work with default gpio configuration
- In the probing, Change voltage control level from level 0 to level 1
- Execute normal dvfs operation on level 1
- After watchdog reset, ap gpio is set by default value
- PMIC operation mode is changed by ap reset (level1 -> level0)
- Regardless of previous vdd_arm voltage, AP always can be booted.

Axel Lin ba3bd8a301 regulator: tps65023: Convert to regulator_list_voltage_table
In current mapping table settings, min_uV/max_uV are always
equal to volt_table[0] and volt_table[table_len -1].
Thus remove min_uV and max_uV from struct tps_info.

The table based mapping with table_len == 1 means fixed voltage.
So we don't need fixed flag to differentiate if it is fixed or not.

This patch adds DCDC_FIXED_3300000_VSEL_table and DCDC_FIXED_1800000_VSEL_table
for fixed voltage cases. So we can convert tps65023_dcdc_ops to
regulator_list_voltage_table. This makes the code simpler.

In case it is misused, also warn if neither linear nor table based mapping

Yadwinder Singh Brar 6f0b2c696c regulator: Add ramp_delay configuration to constraints
For some hardwares ramp_delay for BUCKs is a configurable parameter which can
be configured through DT or board file.This patch adds ramp_delay to regulator
constraints and allow user to configure it for regulators which supports this
feature, through DT or board file. It will provide two ways of setting the
ramp_delay for a regulator:
	First, by setting it as constraints in board file(for configurable
regulators) and set_machine_constraints() will take care of setting it on
hardware by calling(the provided) .set_ramp_delay() operation(callback).
	Second, by setting it as data in regulator_desc(as fixed/default
ramp_delay rate) for a regulator in driver.

regulator_set_voltage_time_sel() will give preference to
constraints->ramp_delay while reading ramp_delay rate for regulator. Similarly
users should also take care accordingly while refering ramp_delay rate(in case
of implementing their private .set_voltage_time_sel() callbacks for different
regulators).

Axel Lin 07b9e329f9 regulator: ab8500: Remove min_uV and max_uV from struct ab8500_regulator_info
The min_uV and max_uV are not really used in the code and misleading because
the min_uV and max_uV settings does not match the value in the voltage table.

For example, we have
static const unsigned int ldo_vaux3_voltages[] = {
        1200000,
        1500000,
        1800000,
        2100000,
        2500000,
        2750000,
        2790000,
        2910000,
};

With below min_uV/max_uV settings for AB8500_LDO_AUX3.
.min_uV                 = 1100000,
.max_uV                 = 3300000,

The min_uV/max_uV for AB8500_LDO_AUX3 seems copy-paste from AB8500_LDO_AUX2

The voltage being set should be passed to the call in handler
requesting the callback.  Currently this is not done.

The calling handler cannot call regulator_get_voltage() to get the
information since the mutex is held by the regulator and
deadlock occurs.

Without this change the receiver of the call in cannot know what
action to take.  This is used, for example, to set PAD voltages
when doing SD vccq voltage changes.

devm_kzalloc call for struct palmas_pmic.

struct palmas_pmic {

Linus Torvalds ac1806572d regulator updates for 3.5
The major thing here is the addition of some helpers to factor code out
 of drivers, making a fair proportion of regulators much more just data
 rather than code which is nice.
 
 - Helpers in the core for regulators using regmap, providing generic
   implementations of the enable and voltage selection operations which
   just need data to describe them in the drivers.
 - Split out voltage mapping and voltage setting, allowing many more
   drivers to take advantage of the infrastructure for selectors.
 - Loads and loads of cleanups from Axel Lin once again, including many
   changes to take advantage of the above new framework features
 - New drivers for Ricoh RC5T583, TI TPS62362, TI TPS62363, TI TPS65913,
   TI TWL6035 and TI TWL6037.
 
 Some of the registration changes to support the core refactoring caused
 so many conflicts that eventually topic branches were abandoned for this
 release.

Mark Brown cd99758ba3 mfd: Convert wm831x to irq_domain
The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.

Axel Lin bae5e9c33f regulator: da903x: Kill da903x_[get|set]_[ldo12|ldo14]_voltage_sel() functions
Now the implementation of da903x_set_voltage_sel, da9030_set_ldo14_voltage_sel,
and da9034_set_ldo12_voltage_sel are exactly the same.

da903x_get_voltage_sel, da9030_get_ldo14_voltage_sel and
da9034_get_ldo12_voltage_sel are exactly the same.

So we can use da903x_[get|set]_voltage_sel and kill other functions.

Laxman Dewangan 9a00630c3d regulator: tps62360: support force PWM mode via regulator mode
Change the mechanism of enabling the force PWM mode through
regulator set mode. This can be dynamically configured now.
In the REGULATOR_MODE_FAST the force PWM is enabled and in
REGULATOR_MODE_NORMAL the force PWM is disabled.
