2013-04-08power: rx51_battery: Fix reporting correct valuesPali Rohár1-0/+1
Tell twl4030_madc_conversion that this driver needs raw values. Driver twl4030_madc has some hardcoded values and conversation functions which are incorrect for Nokia RX-51 board. This driver rx51_battery expects raw values which convert itself. This patch fixing values reported by power supply interface. Before this patch driver reported always incorrect values on 3.8 kernel (sometimes design capacity was negative).

2013-03-18power_supply: Add support for tps65090-chargerRhyland Klein3-0/+323
This patch adds support for the tps65090 charger driver. This driver is responsible for controlling the charger aspect of the tps65090 mfd. Currently, this mainly consists of turning on and off the charger, but some features of the charger can be supported through this driver including: - Enable Auto Recharge based on Battery voltage - Fast Charge Safety Timer - Maximum battery discharge current - Maximum battery adapter current - Enable External Charge - Disable charging termination based on low charger current (supported) Once the driver is accepted, later patches can add support for the features above which are not yet supported.
