9fc3815e26 regulator: tps62360: dt: initialize of_node param for regulator register.
Initialize config.of_node for regulator before registering.
This is needed for DT based regulator support.
Regulator stores this of_node value in rdev->dev.of_node
and used for lookup when client ask for regulator_get().

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.

684ae39b91 regulator: tps62360: add dt support
Add dt support for the pmu device tps62360 and
Add binding documentation with example.
With this patch driver will support both device-tree and
non-device tree registration.

8bdca009e6 regulator: tps62360: make init_data of platform data to pointer.
Convert platform data member regulator_init_data to pointer type.
This will avoid the copy of entire regualator init data into
platform data member when adding dt support and it can be achieve
by simple assignment:
pdata->init_data = of_get_regulator_init_data(dev, dev->of_node);

2935fb18aa regulator: tps62360: fix stylistic issue and optimize code
Fix multiple stylistic issue like:
- The print message should be not break into multiple line.
- line gap after variable declaration and statement.
- checkpatch error.
- some typo.

Some enhancement on error message printing to print error value
also along with proper text.

Avoid voltage_base conversion to microvolts every time.
Put init functions in init section.
Using efficient function inplace of calling multiple function
to reduce the code size.

6c9eeb0f5c regulator: Remove unneeded include of linux/delay.h from regulator drivers
All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.

For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

c172708d38 regulator: core: Use a struct to pass in regulator runtime configuration
Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

d1cf4f65e1 regulator: Add support for tps62362 and tps62363 in tps62360-regulator driver
According to the datasheet[1], tps62360 is register compatible with tps62362.
tps62361B is register compatible with tps62363.
Thus this patch adds support for tps62362 and tps62363.
