| * Input: ad714x - convert to using managed resourcesVaishali Thakkar2015-09-191-10/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | Use managed resource functions devm_request_threaded_irq, devm_inpute_allocate_device and devm_kzalloc to simplify error handling. Also, remove use of input_unregister_device as input_register_device itself handles it and works as resource managed function. To be compatible with the change, various gotos are replaced with direct returns, and unneeded labels are dropped. With these changes remove ad714x_remove and corresponding calls of it as they are now redundant.

| | | | | | | | | | | | | | | Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following build warning when CONFIG_PM_SLEEP is not selected. This is because sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when the CONFIG_PM_SLEEP is enabled. drivers/input/misc/ad714x-i2c.c:17:12: warning: 'ad714x_i2c_suspend' defined but not used [-Wunused-function] drivers/input/misc/ad714x-i2c.c:22:12: warning: 'ad714x_i2c_resume' defined but not used [-Wunused-function] drivers/input/misc/ad714x-spi.c:20:12: warning: 'ad714x_spi_suspend' defined but not used [-Wunused-function] drivers/input/misc/ad714x-spi.c:25:12: warning: 'ad714x_spi_resume' defined but not used [-Wunused-function] Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

* Input: convert SPI drivers to use module_spi_driver()Axel Lin2012-03-171-11/+1Star

* Input: ad714x - read the interrupt status registers in a rowMichael Hennerich2011-08-221-4/+7
| | | | | | | | | | | | | | | | The interrupt status registers should be read in row to avoid invalid data. Alter "read" method for both bus options to allow reading several registers in a row and make sure we read interrupt status registers properly. Read sequence saves 50% of bus transactions compared to single register reads. So use it also for the result registers, which are also located in a row. Also update copyright notice.

* Input: ad714x - use DMA-safe buffers for spi_write()Dmitry Torokhov2011-08-221-14/+37
| | | | | | | | | spi_write() requires use of DMA-safe (cacheline aligned) buffers. Also use the same buffers when reading data since to avoid extra locking and potential memory allocation in spi_write_then_read().

* Input: add Analog Devices AD714x captouch input driverBryan Wu2010-04-141-0/+103
AD7142 and AD7147 are integrated capacitance-to-digital converters (CDCs) with on-chip environmental calibration for use in systems requiring a novel user input method. The AD7142 and AD7147 can interface to external capacitance sensors implementing functions such as buttons, scrollwheels, sliders, touchpads and so on. The chips don't restrict the specific usage. Depending on the hardware connection, one special target board can include one or several these components. The platform_data for the device's "struct device" holds these information. The data-struct defined in head file descript the hardware feature of button/scrollwheel/slider/touchpad components on target boards, which need be filled in the arch/mach-/. As the result, the driver is independent of boards. It gets the components layout from the platform_data, registers related devices, fullfills the algorithms and state machines for these components and report related input events to up level.
