regulator: max8952: Let core handle GPIO descriptor

2018-12-11T01:03:59+00:00

Use the gpiod_get() rather than the devm_* version so that the
regulator core can handle the lifecycle of these descriptors.

regulator: Fetch enable gpiods nonexclusive

2018-10-15T09:48:59+00:00

Since the core regulator code is treating GPIO descriptors as
nonexclusive, i.e. it assumes that the enable GPIO line may be
shared with several regulators, let's add the flag introduced
for fixing this problem on fixed regulators to all drivers
fetching GPIO descriptors to avoid possible regressions.

regulator: max8952: Pass descriptor instead of GPIO number

2018-05-24T15:50:36+00:00

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up with the standard devm_gpiod_get_optional()
call.

All users of this regulator use device tree so the transition is
pretty smooth.

regulator: max8952: constify regulator_ops structure

2017-01-31T20:56:09+00:00

Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

regulator: of: Add regulator desc param to of_get_regulator_init_data()

2014-11-26T18:58:14+00:00

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.

regulator: Set ena_gpio_initialized in regulator drivers

2014-11-07T11:30:25+00:00

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.
