Add support for the Maxim/Dallas DS2780 Stand-Alone Fuel Gauge IC.
It was suggested to combine this functionality with the current ds2782
driver. Unfortunately, I'm unable to commit the time to refactoring this
driver to that extent and I don't have a platform with the ds2782 part to
validate that there are no regression issues by adding this functionality.[akpm@linux-foundation.org: use min_t()]

Fix rated capacity of the HP iPAQ hx4700 3.7V 1800mAh (359113-001) battery. For this battery the value of the rated capacity EEPROM register at 0x32 is 7; thus rated_capacities[7] = 1800.

In 2008 Masashi YOKOTA created the virtual
battery driver found here:
http://downloads.pylone.jp/src/virtual_battery/virtual_battery-0.0.1.tar.bz2It found use out of tree, but was never merged upstream.
Since then the test_power driver has been merged, which provides
very similar functionality.This patch extends the test_power driver to be more dynamic
at runtime, by merging portions of the Virtual Battery Driver
by Masashi YOKOTA.With this patch, I can tweak the values in:
/sys/module/test_power/parameters/* and watch the behavior of
the gnome power managment daemon or other battery UI software.CC: Anton Vorontsov

S390 is special as it doesn't have IRQ lines, so these errors pop up:
drivers/built-in.o: In function 'max8903_remove':

drivers/power/max8903_charger.c:357: undefined reference to 'free_irq'

The ISP1704/1707 chip can be put to full power down
state by asserting the CHIP_SEL line. This patch enables
platform or board specific hooks to put the device into
power down mode in case not needed.This patch is a preparation for enabling this powering
routine in n900 (rx-51) devices.Thanks to Heikki Krogerus for helping out with the patch.

There are a few issues found around the battery not being present. If the
battery isn't present, then a few undesirable things happen. The first was
excessive reporting of failed properties. This was fixed by instead
returning ENODATA for all properties other than PRESENT if the battery
isn't present. That way the callers can identify the difference between a
failure and the battery not being there.The next issue was in the suspend logic. It was found that if the battery
wasn't present, then it would return a failure, preventing the system from
going into suspend. If there is no battery present, the io is expected to
fail, so in that case, we shouldn't return the failure and just
acknowledge that it was expected.I also found that when a gpio was used, i didn't maintain the internal
is_present state properly. I added a set of that to fix that.Lastly, the code to see io's fail and figure out that the battery isn't
present when not using a gpio had a problem. In that code, it looked for
the read to fail and if it did, then handled it. The problem is that in
function to get the property, it first writes a value and that write can
fail, causing the code to never reach the logic after the read. Fix is
to move the logic till after the write.Signed-off-by: Rhyland Klein

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
