2013-03-07ab8500-charger: Add AB8505_USB_LINK_STATUSHakan Berg1-8/+35
The AB8505 does not have the same address for USB link-status as has ab8500. Add AB8505_USB_LINK_STATUS and code to switch to correct constant.

2013-03-07ab8500-fg: Allow capacity to raise from 1% when chargingHakan Berg1-4/+2
When battery capacity was going below 1% fg is not supposed to report 0% unless we've got the LOW_BAT IRQ, no matter what the FG-algorithm says. This made fg get stuck at 1% if charger is connected when capacity is 1%.

2013-03-07ab8500-btemp: Filter btemp readingsHakan Berg1-6/+21
Battery tempreature readings sometimes fail and results in a value far from recent values. This patch adds a software filter that disposes such readings, by allowing direct updates on temperature only if two samples result in the same temperature. Else only allow 1 degree change from previous reported value in the direction of the new measurement.

2013-03-07mfd: ab8500-debug: Add explicit dependenciesLinus Walleij1-0/+3
As I am working on SPARSE_IRQ a number of implicit resource grabs in the kernel become evident. For example, some includes like <linux/irqs.h> would implicitly include <mach/irqs.h> and then from there <mach/db8500-regs.h>. In many cases it is masking the fact that drivers do not properly use resources to pass their dependencies, base addresses etc. So write explicit #include statements with TODO items to have this fixed the proper way to all drivers doing this.
