2016-03-02regulator: helper: Add helper to configure active-discharge using regmapLaxman Dewangan1-0/+14
Add helper function to set the state of active-discharge of regulator using regmap. The HW regulator driver can directly use this by providing the necessary information in the regulator descriptor. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-03-02regulator: core: Add support for active-discharge configurationLaxman Dewangan2-0/+15
Add support to enable/disable active discharge of regulator via machine constraints. This configuration is done when setting machine constraint during regulator register and if regulator driver implemented the callback ops.

2015-08-17regulator: core: Define regulator_set_voltage_triplet()Viresh Kumar1-0/+10
Voltage tolerance isn't necessarily same on both sides of the target voltage and regulator_set_voltage_tol() wouldn't be suitable in such cases. Add another routine regulator_set_voltage_triplet(), which accepts target, min and max voltages as arguments. This first tries to set the voltage between the target voltage and the upper limit, then fall back on the full range. The idea behind this is to set regulator's voltage as close to the target voltage, as possible. Based on regulator_set_voltage_tol().

2015-01-08regulator: Allow parsing custom properties when using simplified DT parsingKrzysztof Kozlowski1-0/+13
When drivers use simplified DT parsing method (they provide 'regulator_desc.of_match') they still may want to parse custom properties for some of the regulators. For example some of the regulators support GPIO enable control. Add a driver-supplied callback for such case. This way the regulator core parses common bindings offloading a lot of code from drivers and still custom properties may be used. The callback, called for each parsed regulator, may modify the 'regulator_config' initially passed to regulator_register().

2014-11-26regulator: of: Pass the regulator description in the match tableJavier Martinez Canillas1-0/+1
Drivers can use the of_regulator_match() function to parse the regulator init_data from DT. A match table is used to specify the name of the node containing the regulators, the device node and to return the init_data to the caller. But also the static regulator descriptor is needed to correctly extract some DT properties like the regulator initial and suspend modes. Use the match table to pass that information.
