Adding support for an optional gpio for battery detection. This is
passed in through the i2c platform data. It also accepts another
field, battery_detect_present to signify the gpio state which means
the battery is present, either 0 (low) or 1 (high).Signed-off-by: Rhyland Klein

The current code only reports whether the battery is charging or
discharging. But the battery also reports whether it is fully charged,
furthermore by look at if the battery is supplied we can tell whether it
is discharging or not charging.Signed-off-by: Lars-Peter Clausen

This patch adds support for polling the battery state and generating a
power_supply_changed() event if it has changed.Signed-off-by: Lars-Peter Clausen
Tested-by: Grazvydas Ignotas -
This patch adds a register cache to the bq27x00 battery driver.
Usually multiple, if not all, power_supply properties are queried at once,
for example when an uevent is generated. Since some registers are used by
multiple properties caching the registers should reduce the number of
reads.The cache is valid for 5 seconds this roughly matches the internal update
interval of the current register for the bq27000/bq27200.Fast changing properties(*_NOW) which can be obtained by reading a single
register are not cached.It will also be used in the follow up patch to check if the battery status
has been changed since the last update to emit power_supply_changed events.Signed-off-by: Lars-Peter Clausen

This patch adds support for the bq27000 battery to the bq27x00 driver.
The bq27000 is similar to the bq27200 except that it uses the HDQ bus
instead of I2C to communicate with the host system.The driver is implemented as a platform driver. The driver expects to be
provided with a read callback function through its platform data. The read
function is assumed to do the lowlevel HDQ handling and read out the value
of a certain register.Signed-off-by: Lars-Peter Clausen

This patch simplifies the drivers data structure and moves code to be
shared by the bq27000 and bq27200/bq27500 init functions into a common

This patch has no functional changes, it only moves code around.Signed-off-by: Lars-Peter Clausen

This patch changes get_property callback of the bq27x00 battery to return

Calling device_add causes an inital uevent for that device to be generated.
The power_supply uevent function calls the drivers get_property function,
which might causes the driver to update its state, which again might
causes the driver to call power_supply_changed(). Since the power_supplys
changed_work has not been initialized at this point the behavior is
undefined and can result in an OOPS.This patch fixes the issue by initializing the power_supplys changed_work
prior to adding the power_supplys device to the device tree.Reported-by: Grazvydas Ignotas

Tested-by: Grazvydas Ignotas -
Sometimes a driver can not report a meaningful value for a certain property
and returns -ENODATA.Currently when generating a uevent and a property return -ENODATA it is
treated as an error an no uevent is generated at all. This is not an
desirable behavior.This patch adds a special case for -ENODATA and ignores properties which
return this error code when generating the uevent.Signed-off-by: Lars-Peter Clausen
