ec454d7016 regulator: arizona-ldo1: Drop OF node reference on error path
We were not calling of_node_put if the regulator failed to register this
patch fixes this.

e6b5be2be4 Driver core patches for 3.19-rc1
Here's the set of driver core patches for 3.19-rc1.
 
 They are dominated by the removal of the .owner field in platform
 drivers.  They touch a lot of files, but they are "simple" changes, just
 removing a line in a structure.
 
 Other than that, a few minor driver core and debugfs changes.  There are
 some ath9k patches coming in through this tree that have been acked by
 the wireless maintainers as they relied on the debugfs changes.
 
 Everything has been in linux-next for a while.

072e78b12b regulator: of: Add regulator desc param to of_get_regulator_init_data()
The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).

Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.

of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.

1de3821ace regulator: Set ena_gpio_initialized in regulator drivers
This patch sets ena_gpio_initialized for all drivers which set a
ena_gpio from parsed DT properties. Drivers using pdata may get zero
initialized pdata and therefore copy a 0 into the regulator_config
ena_gpio field.

7b22b9a5ab regulator: arizona-ldo1: add missing #include
commit 2cce4be9e6 "regulator: arizona-ldo1: Add processing of init_data
from device tree" added a call to of_get_child_by_name() but
did not add an #include to the header file declaring that function.

I got a build error when doing randconfig testing on this, which
is fixed by this patch to include of.h.

4a8c475f5f regulator: arizona-ldo1: Move setup processing from arizona-core
It is more idiomatic to process things relating to the regulator in its
driver. This patch moves both processing of device tree relating to the
regulator and checking if the regulator is external from arizona-core
into the regulator driver.

a35ff28616 regulator: arizona-ldo1: Correct default regulator init_data
Both 5102 and 8997 have the regulator capable of supplying 1.8V, and the
voltage step from the 5110 regulator is different from what is specified
in the default description. This patch updates the default regulator
description to match 5110 and selects the 1.8V capable description for
8997.
