6c794b2654 regulator: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

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.

b21bcd1ada regulator: Add a pointer to aat2870_data in struct aat2870_regulator
The reason we add *pdev in struct aat2870_regulator is to use it
to get a pointer to struct aat2870_data.
Save a pointer to struct aat2870_data instead of pdev in struct
aat2870_regulator, this change makes the intention more clear.

d4d6373c11 regulator: aat2870: Fix the logic of checking if no id is matched in aat2870_get_regulator
In current implementation, the pointer ri is not NULL if no id is matched.
Fix it by checking i == ARRAY_SIZE(aat2870_regulators) if no id is matched.

2c043bcbf2 regulator: pass additional of_node to regulator_register()
With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.
