2014-11-18power: charger-manager: Prevent ktimer's nsecs value exceeds its size.Jonghwa Lee1-1/+2
When charger-manager sets alarmtimer, it has used nanoseconds converted from polling period which is in milliseconds. However ktimer's nanoseconds is limited to represent as size of unsinged long type, and the previous use often exceeds its limitation. It fixes to divide target timer period into seconds part and remains in nanoseconds to prevent abnormal timer period is set.

2014-11-18thermal: introduce device tree parserEduardo Valentin5-1/+880
This patch introduces a device tree bindings for describing the hardware thermal behavior and limits. Also a parser to read and interpret the data and feed it in the thermal framework is presented. This patch introduces a thermal data parser for device tree. The parsed data is used to build thermal zones and thermal binding parameters. The output data can then be used to deploy thermal policies. This patch adds also documentation regarding this API and how to define tree nodes to use this infrastructure. Note that, in order to be able to have control on the sensor registration on the DT thermal zone, it was required to allow changing the thermal zone .get_temp callback. For this reason, this patch also removes the 'const' modifier from the .ops field of thermal zone devices.

2014-11-18power_supply: allow power supply devices registered w/o wakeup sourceZhang Rui1-2/+13
Currently, all the power supply devices are registered with wakeup source, this results in that every power_supply_changed() invocation brings the system out of suspend-to-freeze state. This is overkill as some device drivers, e.g. ACPI battery driver, have the ability to check the device status and wake up the system from sleeping only when necessary. Thus introduce a new API which allows device to be registered w/o wakeup source.

2014-11-18power_supply: Add power_supply notifierPali Rohár1-0/+18
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 Change-Id: I06d5b614d1ad836826f87f24791c94d2fa6c4aa6 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>
2014-11-18power_supply: Fix Oops from NULL pointer dereference from wakeup_source_activateShuah Khan1-6/+6
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.

Backports http://git.linuxtv.org/cgit.cgi/media_tree.git/commit/?id=66cae53024c4 Upstream Author: Shuah Khan <shuah.kh@samsung.com> Original subject: [media] media: fix au0828 dvb suspend/resume to call dvb_frontend_suspend/resume au0828 doesn't resume correctly and TV tuning fails with xc_set_signal_source(0) failed message. Change au0828 dvb suspend and resume interfaces to suspend and resume frontend during suspend and resume respectively. dvb_frontend_suspend() suspends tuner and fe using tuner and fe ops. dvb_frontend_resume() resumes fe and tuner using fe and tuner ops ini before waking up the frontend. With this change HVR950Q suspend and resume work when system gets suspended when digital function is tuned to a channel and with active TV stream, and after resume it went right back to active TV stream.

2014-11-18dma: of: Remove restriction that #dma-cells can't be 0Lars-Peter Clausen1-7/+4
There is no sensible reason why #dma-cells shouldn't be allowed to be 0. It is completely up to the DMA controller how many additional parameters, besides the phandle, it needs to identify a channel. E.g. for DMA controller with only one channel or for DMA controllers which don't have a restriction on which channel can be used for which peripheral it completely legitimate to not require any additional parameters. Also fixes the following warning: drivers/dma/of-dma.c: In function 'of_dma_controller_register': drivers/dma/of-dma.c:67:7: warning: 'nbcells' may be used uninitialized in this function Change-Id: Ibf9738af3bac1d40a630d49b35f9e6450ea100b8 Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
