2016-03-02regulator: core: Add support for active-discharge configurationLaxman Dewangan1-0/+11
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.

2016-03-02regulator: helper: Add helper to configure active-discharge using regmapLaxman Dewangan2-0/+37
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>

2016-02-26regulator: max77620: Remove unused fieldsAxel Lin1-14/+0
These fields are never used and not required at all, remove them. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-02-20regulator: max77620: add regulator driver for max77620/max20024Laxman Dewangan3-0/+835
MAXIM Semiconductor's PMIC, MAX77620 and MAX20024 have the multiple DCDC and LDOs. This supplies the power to different components of the system. Also these rails has configuration for ramp time, flexible power sequence, slew rate etc. Add regulator driver to access these rails via regulator APIs.
