  To: u-boot

PMIC framework has been redesigned to support multiple instances of power related devices
(e.g. fuel gauge, PMICs, chargers, micro USB IC, battery).

Due to that, code at other architectures and boards have been adjusted properly.

New power_init_board() method at ./lib/board.c file has been introduced. It is meant
to be an architecture dependent function to support advanced power management. 
Since PMIC framework uses lists internally to link different devices, its initialization
must be done just after malloc initialization.

Please consider commits from this patch set as the example of advanced power management for a
particular HW (Trats board in this case).

In the new approach PMICs are selected with their names (e.g. 'pmic dump MAX8997_PMIC')
Presented patch set is a first step to change 'pmic' command to more generic (i.e. power)
to provide control for multiple devices.

Moreover device's battery is treated as an oridinary "power" device (like PMIC). Due to
that, framework unification is possible. 
For even more versalite design, each power device instance can specify its parent.

For trats one can build a following scheme (it can de different for other boards):
			-----------------
		--------| BAT		|------------
		|	|		|	    |
		|	-----------------	    |
		|		|		    |
	       \|/	       \|/		   \|/
	-----------	-----------------	---------
	|FG       |	|MUIC		|	|CHRG	|
	|         |	|		| 	|	|
	-----------	-----------------	---------

Finally, this patch series also comprises of a "namespace" cleanup - an attempt to rename
"pmic" to "power" to better reflect generality of this framework.

 - Exynos4210 Trats development board

Since the pmic_reg_read is the u32 value, the order in which bytes
are placed to form u32 value is important.

Support for big and little sensor endianess is added.

Moreover calls to [leXX|beXX]_to_cpu have been added to support
little and big endian SoCs.

Changes for v3:
- New names for sensor endianess (more readable)
- Support for SoCs with different endianess

  To: u-boot

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

It is necessary to introduce a new system wide function- power_init_board()

It turns out, that power initialization must be done as early as possible.
In the case of PMIC framework redesign, which aims to support multiple
instances of PMIC devices the initialization shall be performed just
after malloc configuration.

The power_init_board function is a weak function with default implementation.

Changes for v2:
- None

Changes for v3:
- rename power_board_init to power_init_board
- power_init_board() defined as __weak function with default implementation
- CONFIG_POWER_INIT flag removed since it is not needed

Trats battery is now treated in the same way as other power related
devices. This approach allows for more unified handling of all devices
responsible for power management.

From: Lukasz Majewski @ 2012-10-19 15:43 UTC (permalink / raw)
  To: u-boot

Support for MAX17042 fuel-gauge (FG), which is built into the MAX8997
power management device.
Special file - fg_battery_cell_params.h with cells characteristics
added.

The FG device will work with redesigned PMIC framework.

---
Changes for v2:
- File moved to separate directory at ./drivers/power
- {check|update}_battery available as callbacks from struct power_battery

Changes for v3:
- change code according to struct pmic redesign

When charging battery is necessary, the development board needs to
be turned into low power mode for better efficiency.

Changes for v2:
- Define separate *p_{} pointer instances for each power device available
  at Trats
- Only basic checks performed
- Core responsible for battery charging moved to separate file -
  ./drivers/power/bat_trats.c

Changes for v3:
- None
Changes for v3:
- change code according to struct pmic redesign

Two extra commands:
"pmic name bat state" and "pmic name bat charge" has been added to
pmic framework. Those provides state display and charge capabilities
to named batteries.

The pmic_core.c file has been refactored to more consistent name scheme.

Hi Stefano, Tom,

Any thoughts or ideas for this patch series?

> PMIC framework has been redesigned to support multiple instances of
> power related devices (e.g. fuel gauge, PMICs, chargers, micro USB
> IC, battery).
> 
> Due to that, code at other architectures and boards have been
> adjusted properly.
> 
> New power_init_board() method at ./lib/board.c file has been

> support advanced power management. Since PMIC framework uses lists
> internally to link different devices, its initialization must be done

As will I.  Nothing stands out to me at this point as a problem in the
series.

OK, problem.  This doesn't work with O= building.  You need to convert
these subdirs to building libmax8997.o, etc.

You got me here :-)

I've found this problem when I've been testing the patch series with
MAKEALL script, which cannot duplicate this directory tree at
its ./build dir.

I believe, that those directories are necessary for code readability
and good structure.

I will look into this problem and prepare a proper fix. 

Best regards,
Lukasz Majewski
