5d387d0df9 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.

52a3de5e12 dm: pmic: add max77686 pmic driver
This is the implementation of driver model PMIC driver.
The max77686 PMIC driver implements read/write operations and driver
bind method - to bind its childs.

This driver will try to bind the regulator devices by using it's child
info array with regulator prefixes and driver names. This should succeed
when compatible regulator driver is compiled. If no regulator driver found,
then the pmic can still provide read/write operations, and can be used with
PMIC function calls.

4d9057e82b dm: pmic: add implementation of driver model pmic uclass
This commit introduces the PMIC uclass implementation.
It allows providing the basic I/O interface for PMIC devices.
For the multi-function PMIC devices, this can be used as I/O
parent device, for each IC's interface. Then, each PMIC particular
function can be provided by the child device's operations, and the
child devices will use its parent for read/write by the common API.

Core files:
- 'include/power/pmic.h'
- 'drivers/power/pmic/pmic-uclass.c'

The old pmic framework is still kept and is independent.

For more detailed informations, please look into the header file.

Changes:
- new uclass-id: UCLASS_PMIC
- new config: CONFIG_DM_PMIC

Exynos 5250 boards (snow, spring) use the I2C driver but Exynos 5420 boards
cannot due to a hardware design decision. Select the correct driver to use

2c94611d5f cros_ec: power: Add a tunnelled version of the tps65090 driver
Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.

When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.

ac1058fdb7 power: Add support for TPS65090 PMU chip.
This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure  so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:

- fet enable/disable/querying
- getting and setting of charge state

Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.

The device tree binding is from Linux, but only a small subset of
functionality is supported.

5e2f01772a power: Add support for LTC3676 PMIC
The LTC3676 PMIC includes four DC/DC converters, and three 300mA
LDO Regulators (two Adjustable). The DC/DC converters are adjustable based
on a resistor devider (board-specific).

This adds support for the LTC3676 by creating a namespace unique init function
that uses the PMIC API to allocate a pmic and defines the registers.
