Since 43cc71eed1 ("platform: prefix MODALIAS
with "platform:"), the platform modalias is prefixed with "platform:".
Add MODULE_ALIAS() to the hotpluggable "power" drivers drivers, to
re-enable auto loading.

This mirrors the functionality that driver_for_each_device has as well.
We add a start variable, and all callers of the function are fixed up at
the same time.
The block layer will be using this new functionality in a follow-on
patch.

This patch adds battery monitoring driver for PalmTX.
It can read voltage from the battery and temperature.
It also monitors charging/discharging status.

Commit 54d29ad33e (Power Supply: fix race
in device_create) introduced a race in power_supply_uevent. Previously it
checked that power_supply is available by checking for dev->driver_data.
But now dev->driver_data is set before power_supply->dev is initialised.

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().

As Richard Smith pointed out, ACR * 6250 / 15 provides for less
precision loss than ACR * 4167 / 10, _and_ it doesn't overflow. Switch
to using that equation for CHARGE_COUNTER.

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.

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.

By changing drivers/power/pmu_battery.c I now have '_' instead of
' ' (spaces) in /sys:
/sys/devices/platform/pmu-battery.0/power_supply/PMU_battery_0
/sys/class/power_supply/PMU_battery_0
I'm still not sure if some userspace tool out there uses the old paths and
will break now.

This adds init/exit function callbacks to pda_power, to
provide a place where the platform code can request/free

This adds support for OLPC XO hardware. Open Firmware on XOs don't contain
the VSA, so it is necessary to emulate the PCI BARs in the kernel. This also
adds functionality for running EC commands, and a CONFIG_OLPC.
A number of OLPC drivers depend upon CONFIG_OLPC.
olpc_ec_timeout is a hack to work around Embedded Controller bugs.

power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it. For example, temp_ambient would have the value of
time_to_empty_now. In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.
