power: regulator: Introduce regulator_set_value_force function

2016-11-25T17:00:04+00:00

In case we want to force a particular value on a regulator
irrespective of the min/max constraints for testing purposes
one can call regulator_set_value_force function.

power: regulator: Add ctrl_reg and volt_reg fields for pmic

2016-10-11T16:17:04+00:00

The ctrl reg contains bit fields to enable and disable regulators,
and volt_reg has the bit fields to configure the voltage values.
The registers are frequently accessed hence make them part
of dm_regulator_uclass_platdata structure.

power: regulator: Add support for gpio regulators

2016-10-11T16:17:04+00:00

Add support for gpio regulators. As of now this driver caters
to gpio regulators with one gpio. Supports setting voltage values to gpio
regulators and retrieving the values.

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07+00:00

This new function is more convenient for callers, and handles pre-relocation
situations automatically.

dm: regulator: add function device_get_supply_regulator()

2015-11-02T01:38:00+00:00

Some devices are supplied by configurable regulator's output.
But there was no function for getting it. This commit adds
function, that allows for getting the supply device by it's phandle.

The returned regulator device can be used with regulator uclass's API.

power: regulator: update comments for regulator-name

2015-08-12T08:03:04+00:00

We do not need that "regulator-name" property must be provided in dts.
If "regulator-name" property is not provided in dts, node name
will chosen for settings '.name' field of uc_pdata.

dm: power: Add a function to set up all regulators

2015-07-21T23:39:26+00:00

The device tree provides information about which regulators should be
on at boot, or always on. Use this to set them up automatically.

dm: pmic: Split output from function

2015-07-21T23:39:26+00:00

The regulator_autoset() function mixes printf() output and PMIC adjustment
code. It provides a boolean to control the output. It is better to avoid
missing logic and output, and this permits a smaller SPL code size. So
split the output into a separate function.

Also rename the function to have a by_name() suffix, since we would like
to be able to pass a device when we know it, and thus avoid the name
search.

dm: power: Add regulator flags to centralise auto-set logic

2015-07-21T23:39:26+00:00

Decide when the regulator is set up whether we want to auto-set the voltage
or current. This avoids the complex logic spilling into the processing code.
