* regulator: da9052: Add ramp speed information for the DVC regulatorsPhilipp Zabel2014-02-19
| | | | | | | | Some LDOs and DCDCs have a fixed ramp speed of 6.25 mV/µs. This patch adds the set_voltage_time_sel function to let consumers know about this. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>

Michael reported that with this patch we loose the fix_io code path from da9052_reg_update. Thus revert it.

| | | | | | | | | | | | | | | | | | | | | | | | of_find_node_by_name() returns a node pointer with refcount incremented, use of_node_put() on it when done. of_find_node_by_name() will call of_node_put() against from parameter, thus we also need to call of_node_get(from) before calling of_find_node_by_name().

* regulator: core: Use a struct to pass in regulator runtime configurationMark Brown2012-04-09
| | | | | | | | | | | | | | Rather than adding new arguments to regulator_register() every time we want to add a new bit of dynamic information at runtime change the function to take these via a struct. By doing this we avoid needing to do further changes like the recent addition of device tree support which required each regulator driver to be updated to take an additional parameter. The regulator_desc which should (mostly) be static data is still passed separately as most drivers are able to configure this statically at build time.

* regulator: Refactor to use one da9052_ldo_ops/da9052_dcdc_ops for all LDOs/DCDCsAxel Lin2012-04-01
| | | | | | | | | | | | | | | | | | In current implementation, da9052_ldo_ops and da9052_ldo5_6_ops are very similar, only the set_voltage is slightly different. da9052_buckperi_ops and da9052_dcdc_ops are also similar. This patch adds da9052_regulator_set_voltage for the set_voltage callback used by all LDOs and DCDCs. Rework da9052_get_regulator_voltage_sel and da9052_set_dcdc_voltage to make it possible to be shared by all DCDCs. Rework da9052_list_voltage to make it to be shared by all DCDCs and LDOs. Then we can remove da9052_ldo5_6_ops and da9052_buckperi_ops. We can also remove DA9052_LDO5_6 and DA9052_BUCKPERI macros which is not used now.
