Subject: [PATCH 0/4] Implement device tree support for ab8500 BM Devices
From: "Rajanikanth H.V" <rajanikanth.hv@...ricsson.com>
This patch-set adds device tree binding for ab8500 battery-managed
devices. Removes the redundant platform structure maintained
across bm devices and implements common DT probe routine across all the
modules.
Test status:
a) Tested across 'legacy platform data' and DT binding support
a.1) ab8500_charger driver fails to get regulator in the
legacy platform mode.
b) Interrupt numbers assigned differs between legacy and FDT mode.
(a) Legacy platform_data Mode:

c) Event handlers across bm-modules have been verified only
during 'battery discharge process' as 'battery charging process'
depends on ab8500-usb code
