b996ad0e9f power_supply: Support for Texas Instruments BQ27200 battery managers
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.

b2998049cf [BATTERY] pda_power platform driver
Common power driver for PDAs and phones with one or two external
power supplies (AC/USB) connected to main and backup batteries,
and optional builtin charger.

It's used to stop logic duplication through different embedded
devices. So, power supply *logic* is here. pda_power register
power supplies, and will take care about notifying batteries
about power changes through external power interface.

Currently, power consumption legal limits (including USB power
consumption) should be handled by platform code, inside set_charge
function.
