2013-08-28power_supply: Prevent suspend until power supply events are processedZoran Markovic1-6/+32
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.

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.

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.

This patch prevents NULL pointer error cauesed by unregistering unregistered exton notifier block. At the probing time of charger manager, it tries to remove extcon notifier block when it fails to initialize them. It has to be applied for only registered one. Otherwise, it'd make kernel panic. To make it work right, it checks extcon_specific_cable_nb's extcon_dev node.

2013-06-10PM / AVS: SmartReflex: disable errgen before vpbound disableNishanth Menon1-3/+8
vpboundsintr_en is available inside the IP block as an re-sycned version and one which is not. Due to this, there is an 1 sysclk cycle window where the SR_SInterruptz signal could be asserted low. IF, intr_en is cleared on the exact same cycle as the irqclr, an additional pulse is generated which indicates for VP that an additional adjustment of voltage is required. This results in VP doing two voltage adjustments for the SRERR (based on configuration, upto 4 steps), instead of the needed 1 step. Due to the unexpected pulse from AVS which breaks the AVS-VP communication protocol, VP also ends up in a stuck condition by entering a state where VP module remains non-responsive to any futher AVS adjustment events. This creates the symptom called "TRANXDONE Timeout" scenario. By disabling errgen prior to disable of intr_en, this situation can be avoided.

Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Anton Vorontsov <anton@enomsg.org>
