2013-12-23charger-manager: Modify the way of checking battery's temperatureJonghwa Lee
Charger-manager driver used to check battery temperature through the callback function passed by platform data. Unfortunatley, without that pre-defined callback function, charger-manager can't get battery's temperature at all. Also passing callback function through platform data ruins DT support for charger-manager. This patch mondifies charger-manager driver to get temperature of battery without pre-defined callback function. Now, charger-manager can use either of battery thermometer in fuel-gauge and ouside of battery. It uses thermal framework interface for outer thermometer if thermal fw is enabled. Otherwise, it tries to use fuel-gauge's through the power supply interface.

2013-12-01power_supply: Add power_supply notifierPali Rohár
This patch adds a notifier chain to the power_supply, this helps drivers in other subsystem to listen to changes in power supply subsystem. This would help to take some actions in those drivers on changing the power supply properties. One such scenario is to increase/decrease system performance based on the battery capacity/voltage. Another scenario is to adjust the h/w peak current detection voltage/current thresholds based on battery voltage/capacity. The notifier helps drivers to listen to changes in power_suppy susbystem without polling the power_supply properties Signed-off-by: Jenny TC <jenny.tc@intel.com> Signed-off-by: Pali Rohár <pali.rohar@gmail.com> Acked-by: Jenny TC <jenny.tc@intel.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>

2013-12-01power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activateShuah Khan
power_supply_register() calls device_init_wakeup() to register a wakeup source before initializing dev_name. As a result, device_wakeup_enable() end up registering wakeup source with a null name when wakeup_source_register() gets called with dev_name(dev) which is null at the time. When kernel is booted with wakeup_source_activate enabled, it will panic when the trace point code tries to dereference ws->name. Fixed the problem by moving up the kobject_set_name() call prior to accesses to dev_name(). Replaced kobject_set_name() with dev_set_name() which is the right interface to be called from drivers. Fixed the call to device_del() prior to device_add() in for wakeup_init_failed error handling code. Trace after the change: bash-2143 [003] d... 132.280697: wakeup_source_activate: BAT1 state=0x20001 kworker/3:2-1169 [003] d... 132.281305: wakeup_source_deactivate: BAT1 state=0x30000 Oops message: [ 819.769934] device: 'BAT1': device_add [ 819.770078] PM: Adding info for No Bus:BAT1 [ 819.770235] BUG: unable to handle kernel NULL pointer dereference at (null) [ 819.770435] IP: [<ffffffff813381c0>] skip_spaces+0x30/0x30 [ 819.770572] PGD 3efd90067 PUD 3eff61067 PMD 0 [ 819.770716] Oops: 0000 [#1] SMP [ 819.770829] Modules linked in: arc4 iwldvm mac80211 x86_pkg_temp_thermal coretemp kvm_intel joydev i915 kvm uvcvideo ghash_clmulni_intel videobuf2_vmalloc aesni_intel videobuf2_memops videobuf2_core aes_x86_64 ablk_helper cryptd videodev iwlwifi lrw rfcomm gf128mul glue_helper bnep btusb media bluetooth parport_pc hid_generic ppdev snd_hda_codec_hdmi drm_kms_helper snd_hda_codec_realtek cfg80211 drm tpm_infineon samsung_laptop snd_hda_intel usbhid snd_hda_codec hid snd_hwdep snd_pcm microcode snd_page_alloc snd_timer psmouse i2c_algo_bit lpc_ich tpm_tis video wmi mac_hid serio_raw ext2 lp parport r8169 mii [ 819.771802] CPU: 0 PID: 2167 Comm: bash Not tainted 3.12.0+ #25 [ 819.771876] Hardware name: SAMSUNG ELECTRONICS CO., LTD. 900X3C/900X3D/900X4C/900X4D/SAMSUNG_NP1234567890, BIOS P03AAC 07/12/2012 [ 819.772022] task: ffff88002e6ddcc0 ti: ffff8804015ca000 task.ti: ffff8804015ca000 [ 819.772119] RIP: 0010:[<ffffffff813381c0>] [<ffffffff813381c0>] skip_spaces+0x30/0x30 [ 819.772242] RSP: 0018:ffff8804015cbc70 EFLAGS: 00010046 [ 819.772310] RAX: 0000000000000003 RBX: ffff88040cfd6d40 RCX: 0000000000000018 [ 819.772397] RDX: 0000000000020001 RSI: 0000000000000000 RDI: 0000000000000000 [ 819.772484] RBP: ffff8804015cbcc0 R08: 0000000000000000 R09: ffff8803f0768d40 [ 819.772570] R10: ffffea001033b800 R11: 0000000000000000 R12: ffffffff81c519c0 [ 819.772656] R13: 0000000000020001 R14: 0000000000000000 R15: 0000000000020001 [ 819.772744] FS: 00007ff98309b740(0000) GS:ffff88041f200000(0000) knlGS:0000000000000000 [ 819.772845] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 819.772917] CR2: 0000000000000000 CR3: 00000003f59dc000 CR4: 00000000001407f0 [ 819.773001] Stack: [ 819.773030] ffffffff81114003 ffff8804015cbcb0 0000000000000000 0000000000000046 [ 819.773146] ffff880409757a18 ffff8803f065a160 0000000000000000 0000000000020001 [ 819.773273] 0000000000000000 0000000000000000 ffff8804015cbce8 ffffffff8143e388 [ 819.773387] Call Trace: [ 819.773434] [<ffffffff81114003>] ? ftrace_raw_event_wakeup_source+0x43/0xe0 [ 819.773520] [<ffffffff8143e388>] wakeup_source_report_event+0xb8/0xd0 [ 819.773595] [<ffffffff8143e3cd>] __pm_stay_awake+0x2d/0x50 [ 819.773724] [<ffffffff8153395c>] power_supply_changed+0x3c/0x90 [ 819.773795] [<ffffffff8153407c>] power_supply_register+0x18c/0x250 [ 819.773869] [<ffffffff813d8d18>] sysfs_add_battery+0x61/0x7b [ 819.773935] [<ffffffff813d8d69>] battery_notify+0x37/0x3f [ 819.774001] [<ffffffff816ccb7c>] notifier_call_chain+0x4c/0x70 [ 819.774071] [<ffffffff81073ded>] __blocking_notifier_call_chain+0x4d/0x70 [ 819.774149] [<ffffffff81073e26>] blocking_notifier_call_chain+0x16/0x20 [ 819.774227] [<ffffffff8109397a>] pm_notifier_call_chain+0x1a/0x40 [ 819.774316] [<ffffffff81095b66>] hibernate+0x66/0x1c0 [ 819.774407] [<ffffffff81093931>] state_store+0x71/0xa0 [ 819.774507] [<ffffffff81331d8f>] kobj_attr_store+0xf/0x20 [ 819.774613] [<ffffffff811f8618>] sysfs_write_file+0x128/0x1c0 [ 819.774735] [<ffffffff8118579d>] vfs_write+0xbd/0x1e0 [ 819.774841] [<ffffffff811861d9>] SyS_write+0x49/0xa0 [ 819.774939] [<ffffffff816d1052>] system_call_fastpath+0x16/0x1b [ 819.775055] Code: 89 f8 48 89 e5 f6 82 c0 a6 84 81 20 74 15 0f 1f 44 00 00 48 83 c0 01 0f b6 10 f6 82 c0 a6 84 81 20 75 f0 5d c3 66 0f 1f 44 00 00 <80> 3f 00 55 48 89 e5 74 15 48 89 f8 0f 1f 40 00 48 83 c0 01 80 [ 819.775760] RIP [<ffffffff813381c0>] skip_spaces+0x30/0x30 [ 819.775881] RSP <ffff8804015cbc70> [ 819.775949] CR2: 0000000000000000 [ 819.794175] ---[ end trace c4ef25127039952e ]--- Signed-off-by: Shuah Khan <shuah.kh@samsung.com> Acked-by: Anton Vorontsov <anton@enomsg.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: stable@vger.kernel.org Signed-off-by: Anton Vorontsov <anton@enomsg.org>

This issue was introduced in commit 8e2747f031bd "power: rx51_battery: Replace hardcoded channels values." Original code use channel as argument which was shifted by one in function. After mentioned commit argument is already shifted so we need to get index back. Signed-off-by: Marek Belisko <marek.belisko@open-nandra.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
2013-08-30power: Add twl4030_madc battery driver.Marek Belisko
This driver is used and tested on gta04 phone. It's using twl4030_madc (similar to rx51 existing driver). Driver also implement charging and discharging calibration data so user can define ranges and level.

For __i386__ builds we have: arch/x86/include/uapi/asm/ptrace-abi.h:#define SS 16 And in the driver: BQ24190_SYSFS_FIELD_RO(vbus_stat, SS, VBUS_STAT) That breaks the build like this: drivers/power/bq24190_charger.c:375:138: error: ‘BQ24190_REG_16’ undeclared here (not in a function) drivers/power/bq24190_charger.c:375:162: error: ‘BQ24190_REG_16_THERM_STAT_MASK’ undeclared here (not in a function) drivers/power/bq24190_charger.c:375:203: error: ‘BQ24190_REG_16_THERM_STAT_SHIFT’ undeclared here (not in a function) With this commit we workaround the problem by undefining 'SS'.

2013-08-27power_supply: Prevent suspend until power supply events are processedZoran Markovic
This patch, originally authored by Arve Hjonnevag and Todd Poynor, prevents the system from entering suspend mode until the power supply plug, unplug, or any other change of state event is fully processed. This guarantees that the screen lights up and displays the battery charging state. The implementation uses the power supply wakeup_source object.

2013-08-27bq24190_charger: Add support for TI BQ24190 Battery ChargerMark A. Greer
Add driver support for the Texas Instruments BQ24190 battery charger. Some of the information provided by the device is about the charger and other information is about the battery so create two power_supply objects (one for each) and provide the appropriate information for each one. The device has many fields that go beyond what is reasonable to report or modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver exports the register fields via sysfs. They are prefixed by 'f_' (for 'field') to make it easier to distinguish between a register field and a "normal" sysfs file exported by the power_supply infrastructure. Signed-off-by: Mark A.

2013-08-09power_supply: Make goldfish_battery depend on GOLDFISH || COMPILE_TESTPaul Gortmaker
Nearly all the other goldfish peripherals (mtd, keyboard, etc) have a dependency on the main platform's GOLDFISH Kconfig item, but this one got skipped. Even with consistency as a justification, there was initial resistance[1] from some people to adding it however, as they wanted the extra compile coverage. Now, with CONFIG_COMPILE_TEST, we have the middle ground that will give people the coverage who want it, and let those who don't want it to skip ever seeing the option presented.
