As we know that android doesn't polls for the battery status.
In order to update the battery and power supply related info
created a timer func which polls for every 30Sec and updates
the battery and power supply info.
Also, there is a sysfs attribure "status_poll_period" using
which this polling interval can be altered.
Already, we have these changes in nvec_battery.c which are
wokring and verified. Porting the same changes to
tegra_odm_battery.

1. nvec.h:Correcting enum ordering for NvEcBatterySubtype
as per ECI specs.
NvEcBatterySubtype_SetRemainingCapacityAlarm and
NvEcBatterySubtype_GetRemainingCapacityAlar
>> Verified
2. Registering interrupt for LOW_BAT# from T20 pinmux table:-
GPIO interrupt for Low battery on port w and pin 3
>> Already verified on Wince.
On Android when 0% power is left device
is shutdown. Harmony has this setting around 9.3V which is
less when the battery is at 0%.
3. Enabling LOW_BAT# as a wakeup source 11 from suspend
>> As point no. 2 is wokring this should also work.
This is not verfied as in suspend battery discharge
is slow.
4. Enabling Low capacity alarm as a wakeup source suspend
>> As remaining capacity alarm is working this should also
work.
This is not verfied as in suspend battery discharge
is slow.
5. Setting the 10% of Design capacit as threshold for
Remaining capacity alaram event.
>> Verified
6. Adding 4 functions which are needed for EC firmware validation
NvOdmBatterySetRemCapacityAlarm
NvOdmBatteryGetRemCapacityAlarm
NvOdmBatterySetConfiguration
NvOdmBatteryGetConfiguration

7. Calling kernel_power_off() when device is running on only battery
and it is ctitically low to gracefully shutdown the system.

Bug 646822
Synopsis:[Harmony/android] Battery status is not updated whenever
there is any change in battery/power supply property
- Created a timer of interval 30 Secs which calls the function
tegra_battery_poll_timer_func().
This reports to the power supply core for power supply changes
for Battery, AC and USB.
Which gets the updated info from EC battery driver and signals the uvent.
The JNI and Battery Info application which is waiting on this uevent
then updates themselves with this lateset info from /sys/class/power_supply/*
- Unregsitered to power_supply in remove function.
- Added suspend-resume functions
- Deleting polling timer while suspend and creating it again while resume.

This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
The hardware functions largely autonomously, with minimal software
control required to initiate fast charging.
Support for configuration of the USB supply is not yet implemented.
This means that the hardware will remain in the mode configured at
startup, by default limiting the current drawn from USB to 100mA.
This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.

Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
attribute->owner unnecessary. But the field was left in the structure to
ease the merge. It's been over a year since that change and it is now
time to start killing attribute->owner along with its users - one arch at
a time!
This patch is attempt #1 to get rid of attribute->owner only for
CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on
as and when possible - avr32 will be the next since that is something I
can test. Compile (make allyesconfig / make allmodconfig / custom config)
and boot tested.
akpm: the idea is that we put the declaration of sttribute.owner inside
`#ifndef CONFIG_X86'. But that proved to be too ambitious for now because
new usages kept on turning up in subsystem trees.
[akpm: remove the ifdef for now]

These battery managers came in two different packages: one for I2C
busses (BQ27200) and one for HDQ busses (BQ27000).
This driver currently supports only the I2C chip version but the code
is designed in order to easily allow the HDQ chip version integration.

There is a race from when a device is created with device_create() and
then the drvdata is set with a call to dev_set_drvdata() in which a
sysfs file could be open, yet the drvdata will be NULL, causing all
sorts of bad things to happen.
This patch fixes the problem by using the new function,
device_create_drvdata().

This adds PROP_CHARGE_COUNTER to the power supply class (documenting it
as well). The OLPC battery driver uses this for spitting out its ACR
values (in uAh). We have some rounding errors (the data sheet claims
416.7, the math actually works out to 416.666667, so we're forced to
choose between overflows or precision loss. I chose precision loss,
and stuck w/ data sheet values), but I don't think anyone will care
that much.

Refuse to run with an EC < 0x44. We're playing it safe, and this is a pretty
old EC version.
Also, add a comment about why we're checking the EC version.

Move portions of the massive switch statement into functions. The layout of
this thing has already caused one bug (a break in the wrong place), it needed
to shrink.

This allows you to dump 0x60 bytes from the battery's EEPROM (starting at
address 0x20). Note that it does an EC command for each byte, so it's pretty
slow. OTOH, if you want to grab just a single byte from somewhere in the
EEPROM, you can do something like:
dd bs=1 count=1 skip=16 if=/sys/class/power_supply/olpc-battery/eeprom | od -x
Userspace battery collection/logging information needs this.
