2015-07-14regulator: drivers: Drop owner assignment from i2c_driverKrzysztof Kozlowski1-1/+0
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-26regulator: of: Add regulator desc param to of_get_regulator_init_data()Javier Martinez Canillas1-20/+23
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.

2013-11-24regulator: tps51632: Get regulator name from i2c_clientMikko Perttunen1-1/+1
Commit "i2c: core: make it possible to match a pure device tree driver" changed semantics of the i2c probing for device tree devices. Device tree probed devices now get a NULL i2c_device_id pointer. This causes the regulator name to be set to NULL and the regulator registration to fail. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2012-12-03regulator: tps51632: Ensure [base|max]_voltage_uV pdata settings are validAxel Lin1-0/+15
If pdata->base_voltage_uV is missing or the settings of pdata->base_voltage_uV and pdata->max_voltage_uV are out of range, TPS51632_VOLT_VSEL macro returns wrong vsel. Thus add checking [base|max]_voltage_uV pdata settings in probe.

2012-10-15regulator: tps51632: Add tps51632 regulator driverLaxman Dewangan1-0/+332
The TPS51632 is a driverless step down controller with serial control. Advanced features such as D-Cap+ architecture with overlapping pulse support and OSR overshoot reduction provide fast transient response, lowest output capacitance and high efficiency. The TPS51632 supports both I2C and DVFS interfaces (through PWM) for dynamic control of the output voltage and current monitor telemetry. Add regulator driver for TPS51632.
