59041a5084 arm: am33xx: Fix MPU opp selection
Update MPU frequencies and voltages as per the latest
DM[1] dated: OCT 2011 Revised APRIL 2016, Section 5.4.
Below is the consolidated data:

MPU values for PG 2.0 and later(Package ZCZ and ZCE):

 -------------------------------------------------------
|	|	  ZCZ		|	  ZCE		|
|-------------------------------------------------------|
|	| VDD[V]   | ARM [MHz]	| VDD[V]   | ARM [MHz]  |
|-------|----------|------------|----------|------------|
| NITRO |  1.325   |   1000     |   NA     |    NA      |
|-------|----------|------------|----------|------------|
| TURBO |   1.26   |    800	|   NA     |    NA      |
|-------|----------|------------|----------|------------|
|OPP120 |   1.20   |    720     |   NA     |    NA      |
|-------|----------|------------|----------|------------|
|OPP100 |   1.10   |    600     |   1.10   |    600     |
|-------|----------|------------|----------|------------|
| OPP50 |   0.95   |    300     |   0.95   |    300     |
 -------------------------------------------------------

There is no eFuse blown on PG1.0 Silicons due to which there is
no way to detect the maximum frequencies supported. So default
to OPP100 for which both frequency and voltages are common on both
the packages.

This commit adds unit tests for ADC uclass's methods using sandbox ADC.

Testing proper ADC binding:
- dm_test_adc_bind()                    - device binding
- dm_test_adc_wrong_channel_selection() - checking wrong channel selection

Testing ADC supply operations:
- dm_test_adc_supply():
  - Vdd/Vss values validating
  - Vdd regulator updated value validating
  - Vdd regulator's auto enable state validating

Testing ADC operations results:
- dm_test_adc_single_channel_conversion() - single channel start/data
- dm_test_adc_single_channel_shot()       - single channel shot
- dm_test_adc_multi_channel_conversion()  - multi channel start/data

e8f339e0e8 test: dm: add sandbox PMIC framework tests
This change adds new file to sandbox driver model test environment.
The file is: test/dm/power.c, and it includes tests for PMIC framework,
which includes PMIC uclass and REGULATOR uclass.

All tests are based od Sandbox PMIC emulated device. Some test constants for
this device are defined in the header: include/power/sandbox_pmic.h

PMIC tests includes:
- pmic get - tests, that pmic_get() returns the requested device
- pmic I/O - tests I/O by writing and reading some values to PMIC's registers
             and then compares, that the write/read values are equal.

The regulator tests includes:
- Regulator get by devname/platname
- Voltage set/get
- Current set/get
- Enable set/get
- Mode set/get
- Autoset
- List autoset

For the regulator 'get' test, the returned device pointers are compared,
and their names are also compared to the requested one.
Every other test, first sets the given attribute and next try to get it.
The test pass, when the set/get values are equal.

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.

1757df4693 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.

New file: drivers/power/regulator/max77686.c

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.

af41e8db26 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

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

This is a first of a series of patches - in the future "pmic" will be

Two important issues:
1. The PMIC needs to be initialized just after malloc is configured
2. It uses list to hold information about available PMIC devices
