regulator: fan53555: Constify struct regmap_config and slew_rates array

2015-01-05T20:09:40+00:00

The regmap_config struct may be const because it is not modified by the
driver and regmap_init() accepts pointer to const. Make const also
slew_rates array.

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: fan53555: fix wrong cast in probe

2014-09-17T16:48:59+00:00

The vendor-id gathered from the dt match-data was cast to int but assigned
to an unsigned long, producing warnings on at least sparc, like

   drivers/regulator/fan53555.c: In function 'fan53555_regulator_probe':
>> drivers/regulator/fan53555.c:373:16: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
      di->vendor = (int) match->data;

Fix this by using an appropriate cast.

regulator: fan53555: add support for Silergy SYR82x regulators

2014-09-16T23:09:32+00:00

Silergy SYR82x regulators share the exact same functionality and register layout
as the Fairchild FAN53555 regulators. Therefore extend the driver to add
support for them.

Both types use the same vendor id in their ID1 register, so it's not possible
to distinguish them automatically.

Similarly, the types also do not match. Type 8 used by the SYR827 and SYR828
start at 712.5mV and increment in 12.5mv steps, while the FAN53555 type 8
starts at 600mV and increments in 10mV steps.

regulator: fan53555: use set_ramp_delay to set the ramp up slew rate

2014-09-16T16:56:11+00:00

The regulator constraints already provide a field for the ramp_delay, so
there is no need to set this manually. Therefore implement the set_ramp_delay
callback and convert the pdata value to the constraint value if necessary.
