* mfd: hi6421-pmic: Add support for HiSilicon Hi6421v530Guodong Xu2017-09-051-18/+52
| | | | | | | | | | | | | | | Add support for HiSilicon Hi6421v530 PMIC. Hi6421v530 communicates with main SoC via memory-mapped I/O. Hi6421v530 and Hi6421 are PMIC chips from the same vendor, HiSilicon, but at different revisions. They share the same memory-mapped I/O design. They differ in integrated devices, such as regulator details, LDO voltage points.

* mfd: hi6421-pmic: Use devm_mfd_add_devices() for mfd_device registrationLaxman Dewangan2016-04-191-10/+2
| | | | | | | | | | Use devm_mfd_add_devices() for MFD devices registration and get rid of .remove callback to remove MFD child-devices. This is done by managed device framework.

* mfd: hi6421-pmic: Fix module autoload for OF platform driverLuis de Bethencourt2015-10-261-0/+1
| | | | | | | | This platform driver has a OF device ID table but the OF module alias information is not created so module autoloading won't work. Signed-off-by: Luis de Bethencourt <luisbg@osg.samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: Constify of_device_id arrayFabian Frederick2015-03-261-1/+1

* mfd: hi6421-pmic: Constify struct regmap_configKrzysztof Kozlowski2015-01-221-1/+1
| | | | | | | | The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: Add HI6421 PMIC Core driverGuodong Xu2014-09-261-0/+113
This adds driver to support HiSilicon Hi6421 PMIC. Hi6421 includes multi- functions, such as regulators, codec, ADCs, Coulomb counter, etc. This driver includes core APIs _only_. Drivers for individul components, like voltage regulators, are implemented in corresponding driver directories and files. Registers in Hi6421 are memory mapped, so using regmap-mmio API.
