This driver implements regulator operations for fixed Voltage/Current value regulators. beside the standard regulator constraints, which are put into the uclass platform data, a typical fixed regulator node provides few additional properties like:
- gpio
- gpio-open-drain
- enable-active-high
- startup-delay-us
The only 'gpio' is used by this driver and is kept in structure of type 'fixed_regulator_platdata', as a device platform data (dev->platdata).
The driver implements:
- get_value
- get_current
- get_enable
- set_enable
The regulator calls and commands can be used for fixed-regulator devices, and the proper error will be returned for prohibited.

Changes v3:
- new file
- Kconfig add fixed-regulator entry
Changes V4:
- move DM_REGULATOR_FIXED Kconfig entry from: drivers/power/Kconfig to drivers/power/regulator/Kconfig
- regulator/fixed.c: adjust to use of uclass platdata and device platdata
- regulator/fixed.c: includes cleanup
- regulator/fixed.c: fix gpio request
- add binding info
