This series add the driver support for AMS AS3722 PMIC. The driver includes MFD, pincontrol and GPIO, regulator and RTC.

Changes from V1: 
- Remove compatible string from DT for subnode.
- Add macro in regmap.h for definign range.
- Nit cleanups in driver and use module_i2c_driver/module_platform_driver.
- Use linear_range and added regulator_map_* on regulators.
- Move OC configuration to regulator_current limit setting.
- Get rid of clk32k out configuration from RTC. Will add clock driver.

Changes from V2: 
- Drop the already applied patches on V2 series
        regmap: add helper macro to set min/max range of register
        regulator: as3722: add regulator driver for AMS AS3722
- Move the GPIo driver to pincontrol driver to expose the pin configuration
  through pincontrol.
- rewrite the DT binding of the mfd.

Changes from V3:
- Change AMS to ams
- combine DT of regulator, pincontrol to the mfd.
- Taken care of Lee's nits feedback.

Changes from V4:
- Rephrased the DT binding document.
- Add header for dt-binding macros.
