425846ed8f power: pmic.h: Drop include <spi.h>
include/power/pmic.h never used any generic spi code
from include/spi.h, but this has been added in below commit.
"dm: pmic: add implementation of driver model pmic uclass"
(sha1: 4d9057e82b)

Adding functionalities in include/spi.h will trigger a build
issue as this been added used in include/power/pmic.h

Build issue on trats2 with adding BIT macro on spi.h:

f415a3ec9d dm: pmic: code cleanup of PMIC uclass driver
The cleanup includes:
- pmic.h - fix mistakes in a few comments
- pmic operations: value 'reg_count' - redefine as function call
- fix function name: pmic_bind_childs() -> pmic_bind_children()
- pmic_bind_children: change the 'while' loop with the 'for'
- add implementation of pmic_reg_count() method
- pmic_bind_children() - update function call name
- Kconfig: add new line at the end of file
- Update MAX77686 driver code

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

5c44dd6bbd power/pmic.h: Add prototype for power_init_board.
As this is a weak function that we may override, provide a prototype for
it.

78a36c3ef3 power: Add PMIC_ prefix to CHARGER_EN/DISABLE
This enum should be common across all PMICs rather than having it
independently defined with the same name in multiple places.

c733681507 pmic: Extend PMIC framework to support multiple instances of PMIC devices
The PMIC framework has been extended to support multiple instances of
the variety of devices responsible for power management.
This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB
Interface Circuit).
Power related includes have been moved to ./include/power directory.
This is a first of a series of patches - in the future "pmic" will be
replaced with "power".

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
