2009-11-16 | wm831x: Factor out WM831x backup battery charger | Mark Brown | 1 | -141/+3 | |
The backup battery on WM831x is a separate IP block to the main PMU and is largely unrelated to the main supply functionality. Factor it out into a separate driver in order to reflect this and better support future hardware versions.

2009-09-04 | power_supply: Add driver for the PMU on WM831x PMICs | Mark Brown | 1 | -0/+779 | |
The WM831x PMICs provide power path management from three sources: a wall supply, USB and a battery with integrated charger. They also provide an additional backup supply with integrated for maintaining always on functionality such as the RTC and monitoring of power switches. After some initial configuration at startup the device operates autonomously, the driver simply provides reporting of the current state.
