"pdata" and "pchg->pdata" are the same. Changing the function call to pdata->get_batt_present() makes it match the check and it's a little cleaner. Signed-off-by:

Pull a huge ab8500/pm2301 pile of changes from Lee Jones. Lee did an awesome job cleaning this stuff up and thus brought ab8500 Stericsson's development tree much closer to the mainline. Even more changes to come, though. Conflicts: drivers/power/Kconfig

Power supply subsystem creates thermal zone device for the property 'POWER_SUPPLY_PROP_TEMP' which requires thermal subsystem to be ready before 'ab8500 battery temperature monitor' driver is initialized. ab8500 btemp driver is initialized with subsys_initcall whereas thermal subsystem is initialized with fs_initcall which causes thermal_zone_device_register(...) to crash since the required structure 'thermal_class' is not initialized yet: Unable to handle kernel NULL pointer dereference at virtual address 000000a4 pgd = c0004000 [000000a4] *pgd=00000000 Internal error: Oops: 5 [#1] PREEMPT SMP ARM Modules linked in: CPU: 0 Tainted: G W (3.8.0-rc4-00001-g632fda8-dirty #1) PC is at _raw_spin_lock+0x18/0x54 LR is at get_device_parent+0x50/0x1b8 pc : [<c02f1dd0>] lr : [<c01cb248>] psr: 60000013 sp : ef04bdc8 ip : 00000000 fp : c0446180 r10: ef216e38 r9 : c03af5d0 r8 : ef275c18 r7 : 00000000 r6 : c0476c14 r5 : ef275c18 r4 : ef095840 r3 : ef04a000 r2 : 00000001 r1 : 00000000 r0 : 000000a4 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment kernel Control: 10c5787d Table: 0000404a DAC: 00000015 Process swapper/0 (pid: 1, stack limit = 0xef04a238) Stack: (0xef04bdc8 to 0xef04c000) [...] [<c02f1dd0>] (_raw_spin_lock+0x18/0x54) from [<c01cb248>] (get_device_parent+0x50/0x1b8) [<c01cb248>] (get_device_parent+0x50/0x1b8) from [<c01cb8d8>] (device_add+0xa4/0x574) [<c01cb8d8>] (device_add+0xa4/0x574) from [<c020b91c>] (thermal_zone_device_register+0x118/0x938) [<c020b91c>] (thermal_zone_device_register+0x118/0x938) from [<c0202030>] (power_supply_register+0x170/0x1f8) [<c0202030>] (power_supply_register+0x170/0x1f8) from [<c02055ec>] (ab8500_btemp_probe+0x208/0x47c) [<c02055ec>] (ab8500_btemp_probe+0x208/0x47c) from [<c01cf0dc>] (platform_drv_probe+0x14/0x18) [<c01cf0dc>] (platform_drv_probe+0x14/0x18) from [<c01cde70>] (driver_probe_device+0x74/0x20c) [<c01cde70>] (driver_probe_device+0x74/0x20c) from [<c01ce094>] (__driver_attach+0x8c/0x90) [<c01ce094>] (__driver_attach+0x8c/0x90) from [<c01cc640>] (bus_for_each_dev+0x4c/0x80) [<c01cc640>] (bus_for_each_dev+0x4c/0x80) from [<c01cd6b4>] (bus_add_driver+0x16c/0x23c) [<c01cd6b4>] (bus_add_driver+0x16c/0x23c) from [<c01ce54c>] (driver_register+0x78/0x14c) [<c01ce54c>] (driver_register+0x78/0x14c) from [<c00086ac>] (do_one_initcall+0xfc/0x164) [<c00086ac>] (do_one_initcall+0xfc/0x164) from [<c02e89c8>] (kernel_init+0x120/0x2b8) [<c02e89c8>] (kernel_init+0x120/0x2b8) from [<c000e358>] (ret_from_fork+0x14/0x3c) Code: e3c3303f e5932004 e2822001 e5832004 (e1903f9f) ---[ end trace ed9df72941b5bada ]--- Signed-off-by:

If charging is started before USB enumeration of an Accessory Charger Adapter has finished, the AB8500 will generate a VBUS_ERROR. This in turn results in timeouts and delays the enumeration with around 15 seconds. This patch delays the charging and then ramps currents slowly to avoid VBUS errors. The delay allows the enumeration to have finished before charging is turned on. Signed-off-by:

When the charging safety timer elapses, the battery health is shown as "Good". This is misleading and also makes it difficult to distinguish issues relating to discharging despite the fact that the charger is still connected. When in actual fact a safety timer elapse is an indication of a fault in the battery. Here we make this clearer by reporting POWER_SUPPLY_HEALTH_UNSPEC_FAILURE instead. Signed-off-by: -

Today the battery recharge is determined with a voltage threshold. This voltage threshold is only valid when the battery is relaxed. In charging algorithm the voltage read is the loaded battery voltage and no compensation is done to get the relaxed voltage. When maintenance charging is not selected, this makes the recharging condition to almost immediately activate when there is a discharge present on the battery. Depending on which vendor the battery comes from this behavior can wear out the battery much faster than normal. The fuelgauge driver is responsible to monitor the actual battery capacity and is able to estimate the remaining capacity. It is better to use the remaining capacity as a limit to determine when battery should be recharged. Signed-off-by:
