inputs.
This driver takes care a allocating a free irq and then configuring the
crossbar IP as a part of the mpu's irqchip callbacks. crossbar_init should
be called right before the irqchip_init, so that it is setup to handle the
irqchip callbacks.

[PATCH v2 0/6] IIO pulse capture support for TI ECAP
Changes since v1: - Rebased to 3.14-rc1 - Renamed in_pulse_polarity to pulse_polarity - Added ABI entries for pulse devices and TI ECAP This series adds support for PWM capture devices within IIO and adds a TI ECAP IIO driver. PWM capture devices are supported using a new IIO pulse channel type. The IIO ECAP driver implements interrupt driven triggered buffer capture only as raw sample reads are not applicable to this hardware. Initially, the driver supports a single pulse width measurement with configurable polarity. The ECAP hardware can support measurement of a complete period and duty cycle but this is not yet implemented.

[PATCH v5 0/4] power_supply: Introduce power supply charging driver
v1: introduced feature as a framework within power supply class driver with separate files for battid framework and charging framework v2: fixed review comments, moved macros and inline functions to power_supply.h v3: moved the feature as a separate driver, combined battid framework and charging framework inside the power supply charging driver. Moved charger specific properties to power_supply_charger.h and plugged the driver with power supply subsystem using power_supply_notifier introduced in my previous patch. Also a sample charger chip driver (bq24261) patch added to give more idea on the psy charging driver usage v4: Fixed review comments, no major design changes. v5: Fixed makefile inconsistencies, removed unused pdata callbacks The Power Supply charging driver connects multiple subsystems to do charging in a generic way. The subsystems involves power_supply, thermal and battery communication subsystems (1wire).With this the charging is handled in a generic way. The driver makes use of different new features - Battery Identification interfaces, pluggable charging algorithms, charger cable arbitrations etc. The patch also introduces generic interface for charger cable notifications. Charger cable events and capabilities can be notified using the generic power_supply_notifier chain. Overall this driver removes the charging logic out of the charger chip driver and the charger chip driver can just listen to the request from the power supply charging driver to set the charger properties. This can be implemented by exposing get_property and set property callbacks.

[PATCH 3/4] power_supply: Introduce PSE compliant algorithm
As per Product Safety Engineering (PSE) specification for battery charging, the
battery characteristics and thereby the charging rates can vary on different
temperature zones. This patch introduces a PSE compliant charging algorithm with
maintenance charging support. The algorithm can be selected by the power supply
charging driver based on the type of the battery charging profile.
