Max8925 ldo status should be determined by two factors:
1. power up/down sequence selection(LDOCTL[4:2]).
2. i2c enable bit(LDOCTL[0]).Max8925 ldo support two types of power up/down sequence:
1. flexible sequence(LDOCTL[4:2] = 0~6).
2. i2c sequence(LDOCTL[4:2] = 7).With flexible sequence selected, the ldo is enabled during power up by default.
With i2c sequence selected, the ldo is controlled by the i2c enable bit(LDOCTL[0]).Signed-off-by: Kevin Liu

During regulator_register, the rail is set on the provided
machine constraints and if it is enabled then it is also
require to enable the supply regulator. This will make sure
that:
1. Proper reference count for supply regulator to be maintain.
2. Supply regulator should be enable when given rail is enabled.Signed-off-by: Laxman Dewangan

The Dialog PMIC has below featured regulators:-
DA9052-BC - 4 DVS Buck converters 0.5V - 3.6V upto 1Amp.
DA9053-AA/BX - 4 DVS Buck converters 0.5V - 2.5V upto 3Amp.
DA9052/53 - 10 Programmable LDO's High PSSR, 1% accuracy.This patch support all the DA9052 and Da9053 regulators. The output voltages are
fully programmable via I2C or SPI interface. The platform data with regulation
constraints is passed down from the board to the regulator.Signed-off-by: David Dajun Chen

…/regulator into regulator-next

It's not always true that the device_node of regulator can be found
at dev->of_node at the time when of_get_regulator_init_data() is being
called, because in some cases the regulator nodes in device tree do
not have 'struct device' behind them until regulator_dev gets created
for it by core function regulator_register().The patch adds device_node as a new parameter to
of_get_regulator_init_data(), so that caller can pass in the node of
regulator directly.Signed-off-by: Shawn Guo

Otherwise there is no way in the bindings to configure a fixed voltage
via software. It seems reasonable to assume that if the binding explicitly
specifies a voltage we want to actually use that voltage.Signed-off-by: Mark Brown

SMPS regulator voltage control differs from the one of the LDO ones.
Current TWL code was using LDO regulator ops for controlling the SMPS
regulators, which fails. This was fixed fixed by adding separate
regulator type which uses correct logic and calculations for the
voltage levels.Signed-off-by: Tero Kristo

This is caused by dereferencing 'rdev' after device_unregister() in
the regulator_unregister() function. 'rdev' is freed by
device_unregister(), so it must not be dereferenced after this call.[Edited commit message for legibility -- broonie]

updating the regulator_register() call in gpio-regulator.c with
the additional parameter (NULL).The compile break as reported by Stephen Rothwell with the

…e/regulator into regulator-next

Device nodes in DT can associate themselves with one or more
regulators/supply by providing a list of phandles (to regulator nodes)
and corresponding supply names.For Example:
devicenode: node@0x0 {
...
...
vmmc-supply = ;
vpll-supply = ;
};The driver would then do a regulator_get(dev, "vmmc"); to get
regulator1 and do a regulator_get(dev, "vpll"); to get
regulator2.of_get_regulator() extracts the regulator node for a given
device, based on the supply name.Use it to look up the regulator for a given consumer from device tree, during
a regulator_get(). If not found fallback and lookup through
the regulator_map_list instead.Also, since the regulator dt nodes can use the same binding to
associate with a parent regulator/supply, allow the drivers to
specify a supply_name, which can then be used to lookup dt
to find the parent phandle.Signed-off-by: Rajendra Nayak
