dm: regulator: add implementation of driver model regulator uclass This commit introduces the implementation of dm regulator API. Device tree support allows for auto binding. And by the basic uclass operations, it allows to driving the devices in a common way. For detailed informations, please look into the header file. Core files: - drivers/power/regulator-uclass.c - provides regulator common functions api - include/power/regulator.h - define all structures required by the regulator Changes: - new uclass-id: UCLASS_REGULATOR - new config: CONFIG_DM_REGULATOR Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org>

config DM_REGULATOR
bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
depends on DM
---help---
This config enables the driver model regulator support.
UCLASS_REGULATOR - designed to provide a common API for basic regulator's
functions, like get/set Voltage or Current value, enable state, etc...
Note:
When enabling this, please read the description, found in the files:
- 'include/power/pmic.h'
- 'include/power/regulator.h'
- 'drivers/power/pmic/pmic-uclass.c'
- 'drivers/power/pmic/regulator-uclass.c'
It's important to call the device_bind() with the proper node offset,
when binding the regulator devices. The pmic_bind_childs() can be used
for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_node()
dm: regulator: uclass driver code cleanup This cleanup includes: - remove of the preprocessor macros which pointed to long name functions - update of the names of some regulator uclass driver functions - cleanup of the function regulator_autoset() - reword of some comments of regulator uclass header file - regulator_get_by_platname: check error for uclass_find_* function calls - add function: regulator_name_is_unique - regulator post_bind(): check regulator name uniqueness - fix mistakes in: regulator/Kconfig - regulator.h: update comments - odroid u3: cleanup the regulator calls Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Acked-by: Simon Glass <sjg@chromium.org> Tested on sandbox: Tested-by: Simon Glass <sjg@chromium.org>

dm: regulator: add max77686 regulator driver This commit adds support to MAX77686 regulator driver, based on a driver model regulator's API. It implements almost all regulator operations, beside those for setting and geting the Current value. For proper bind and operation it requires the MAX77686 PMIC driver.

config DM_REGULATOR_MAX77686
bool "Enable Driver Model for REGULATOR MAX77686"
depends on DM_REGULATOR && DM_PMIC_MAX77686
---help---
This config enables implementation of driver-model regulator uclass
features for REGULATOR MAX77686. The driver implements get/set api for:
value, enable and mode.
dm: regulator: add fixed voltage regulator driver 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.

---help---
This config enables implementation of driver-model regulator uclass
features for fixed value regulators. The driver implements get/set api
for enable and get only for voltage value.
sandbox: add: sandbox PMIC device drivers: I2C emul, pmic, regulator This commit adds emulation of sandbox PMIC device, which includes: - PMIC I2C emulation driver - PMIC I/O driver (UCLASS_PMIC) - PMIC regulator driver (UCLASS_REGULATOR) The sandbox PMIC has 12 significant registers and 4 as padding to 16 bytes, which allows using 'i2c md' command with the default count (16). The sandbox PMIC provides regulators: - 2x BUCK - 2x LDO Each, with adjustable output: - Enable state - Voltage - Current limit (LDO1/BUCK1 only) - Operation mode (different for BUCK and LDO) Each attribute has it's own register, beside the enable state, which depends on operation mode. The header file: sandbox_pmic.h includes PMIC's default register values, which are set on i2c pmic emul driver's probe() method.

dm: power: Add support for S5M8767 regulators This PMIC is used with SoCs which need a combination of BUCKs and LDOs. The driver supports changing voltage and enabling/disabling each regulator. It supports the standard device tree binding and supports driver model. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Przemyslaw Marczak <p.marczak@samsung.com>

config REGULATOR_S5M8767
bool "Enable support for S5M8767 regulator"
depends on DM_REGULATOR && PMIC_S5M8767
---help---
This enables the regulator features of the S5M8767, allowing voltages
to be set, etc. The driver is not fully complete but supports most
common requirements, including all LDOs and BUCKs. This allows many
supplies to be set automatically using the device tree values.

config DM_REGULATOR_SANDBOX
bool "Enable Driver Model for Sandbox PMIC regulator"
depends on DM_REGULATOR && DM_PMIC_SANDBOX
---help---
Enable the regulator driver for emulated Sandbox PMIC.
The emulated PMIC device depends on two drivers:
- sandbox PMIC I/O driver - implements dm pmic operations
- sandbox PMIC regulator driver - implements dm regulator operations
- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
The regulator driver provides uclass operations for sandbox PMIC's
regulators. The driver implements get/set api for: voltage, current,
operation mode and enable state.
The driver supports LDO and BUCK regulators.
The Sandbox PMIC info:
* I/O interface:
- I2C chip address: 0x40
- first register address: 0x0
- register count: 0x10
* Adjustable outputs:
- 2x LDO
- 2x BUCK
- Each, with a different operating conditions (header).
* Reset values:
- set by i2c emul driver's probe() (defaults in header)
A detailed information can be found in header: '<power/sandbox_pmic.h>'

dm: power: Add support for TPS65090 FETs The TPS65090 has 7 FETs which are modelled as regulators. This allows them to be controlled by drivers easier, accessed through the 'regulator' command and used by other drivers.

config REGULATOR_TPS65090
bool "Enable driver for TPS65090 PMIC regulators"
depends on PMIC_TPS65090
---help---
The TPS65090 provides several FETs (Field-effect Transistors,
effectively switches) which are supported by this driver as
regulators, one for each FET. The standard regulator interface is
supported, but it is only possible to turn the regulators on or off.
There is no voltage/current control.
