2012-11-19ab8500: Add devicetree support for fuelgaugeRajanikanth H.V1-40/+42
- This patch adds device tree support for fuelgauge driver - optimize bm devices platform_data usage and of_probe(...) Note: of_probe() routine for battery managed devices is made common across all bm drivers. - test status: - interrupt numbers assigned differs between legacy and FDT mode.

2012-10-07Merge tag 'for-v3.7' of git://git.infradead.org/battery-2.6Linus Torvalds1-0/+1
Pull battery updates from Anton Vorontsov: "1. New drivers: - Marvell 88pm860x charger and battery drivers; - Texas Instruments LP8788 charger driver; 2. Two new power supply properties: whether a battery is authentic, and chargers' maximal currents and voltages; 3. A lot of TI LP8727 Charger cleanups; 4. New features for Charger Manager, mainly now we can disable specific regulators; 5. Random fixes and cleanups for other drivers."

2012-08-23ab8500_fg: Fix error return codeJulia Lawall1-0/+1
Initialize return variable before exiting on an error path. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Anton Vorontsov <anton.vorontsov@linaro.org>

2012-05-05ab8500_fg: Harden platform data checkLinus Walleij1-2/+2
If no platform data at all is supplied the driver crashes, extend the checks to be more careful so we can compile in the driver and boot also without platform data present.
