Subject[PATCH 0/4] Implement device tree support for ab8500 BM Devices
Date
From: "Rajanikanth H.V" <rajanikanth.hv@stericsson.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:
root@ME:/ cat /proc/interrupts
CPU0 CPU1
483: 0 0 ab8500 ab8500-ponkey-dbf
484: 0 0 ab8500 ab8500-ponkey-dbr
485: 0 0 ab8500 BATT_OVV
494: 0 1 ab8500
495: 0 0 ab8500 ab8500-rtc
501: 0 13 ab8500 NCONV_ACCU
503: 7 22 ab8500 CCEOC
504: 0 1 ab8500 CC_INT_CALIB
505: 0 0 ab8500 LOW_BAT_F
516: 0 34 ab8500 ab8500-gpadc
556: 0 0 ab8500 usb-link-status

(b) FDT Mode:
root@ME:/ cat /proc/interrupts
CPU0 CPU1
6: 0 0 ab8500 ab8500-ponkey-dbf
7: 0 0 ab8500 ab8500-ponkey-dbr
8: 0 0 ab8500 BATT_OVV
162: 0 7 ab8500 ab8500-gpadc
163: 0 1 ab8500
164: 0 0 ab8500 ab8500-rtc
484: 0 0 ab8500 usb-link-status
499: 0 4 ab8500 NCONV_ACCU
500: 0 0 ab8500 LOW_BAT_F
502: 0 1 ab8500 CC_INT_CALIB
503: 0 6 ab8500 CCEOC

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

Rajanikanth H.V (4):
mfd: ab8500: add devicetree support for fuelgauge
mfd: ab8500: add devicetree support for btemp
mfd: ab8500: add devicetree support for charger
mfd: ab8500: add devicetree support for chargalg
