2014-10-20regulator: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>

2014-08-21regulator: hi6421: Remove unused fields from struct hi6421_regulator_infoAxel Lin
The valid_modes_mask and *dev are not used in this driver, remove them. Current code uses devm_regulator_register, so we don't need *regulator in hi6421_regulator_info. Use a local variable instead. Also removes a few unnecessary inclusion of header files. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-08-19regulator: hi6421: style fix, else with a single return is not requiredGuodong Xu
style fix for warnings. 'else' with a single 'return' is usually not required. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
2014-08-16regulator: add driver for hi6421 voltage regulatorGuodong Xu
Add driver support for HiSilicon Hi6421 voltage regulators. Two rules for regulator enabling are defined in hi6421 spec: 1) Between disable and enable of each regulator (LDOs or BUCKs), there must be a protection gap. Use @off_on_delay of regulator core to implement this. 2) No two regulators can be enabled at the same time. Use mutex in hi6421_regulator_pdata to ensure this. A protection gap of 100us is added into each LDO/BUCK's .enable_time. Signed-off-by: Guodong Xu <guodong.xu@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>
