upowerd wants to compute the energy in the battery by looking at this property. If it's not present then it falls back on using the reported voltage of the battery at time upowerd loads. That's close but also means that every time you boot you get a slightly different energy capacity. Adding the VOLTAGE_MAX_DESIGN property allows upowerd to compute the same energy every time.

The patches adding support for CURRENT_NOW, VOLTAGE_NOW, CHARGE_NOW and CHARGE_FULL_DESIGN were based on a tree not including c566d299 ("olpc_battery: Ambient temperature is not available on XO-1.5") and therefore only modified the then-common, now-XO-1 properties list.

CHARGE_NOW is needed by some user space software (read: UPower) for internal calculations.

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.

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.

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.

The CAPACITY_LEVEL stuff defines various levels of charge; however, what is the difference between them? What differentiates between HIGH and NORMAL, LOW and CRITICAL, etc? As it appears that these are fairly arbitrary, we end up making such policy decisions in the kernel (or in hardware). This is the sort of decision that should be made in userspace, not in the kernel. If the hardware does not support _CAPACITY and it cannot be easily calculated, then perhaps the driver should register a custom CAPACITY_LEVEL attribute; however, userspace should not become accustomed to looking for such a thing, and we should certainly not encourage drivers to provide CAPACITY_LEVEL stubs. The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The OLPC battery driver is the only driver making use of this, so it's removed from there as well.
