ds2760_battery.c: fix division by zero

2009-03-12T23:20:23+00:00

The 'battery remaining capacity' calculation in
drivers/power/ds2760_battery.c lacks a parameter check to a division
operation which causes the kernel to oops on my board.

power_supply: pda_power: Don't request shared IRQs w/ IRQF_DISABLED

2009-01-25T23:09:26+00:00

IRQF_DISABLED is not guaranteed for shared IRQs. I think power_changed_isr
doesn't need it anyway, as it only fires a timer.
This patch enables IRQF_SAMPLE_RANDOM instead.

power_supply: Add battery health reporting for WM8350

2009-01-04T11:17:39+00:00

Implement support for reporting battery health in the WM8350 battery

the diagnostics from the interrupt handler.

power_supply: Add support for WM8350 PMU

2009-01-04T11:17:38+00:00

This patch adds support for the PMU provided by the WM8350 which
implements battery, line and USB supplies including a battery charger.
The hardware functions largely autonomously, with minimal software
control required to initiate fast charging.

Support for configuration of the USB supply is not yet implemented.
This means that the hardware will remain in the mode configured at
startup, by default limiting the current drawn from USB to 100mA.

This driver was originally written by Liam Girdwood with subsequent
updates for submission by Mark Brown.
