Input: tsc2007 - add iio interface to read external ADC input and temperature

2017-02-17T21:21:55Z

The tsc2007 chip not only has a resistive touch screen controller but also an external AUX adc imput which can be used for an ambient light sensor, battery voltage monitoring or any general purpose. Additionally it can measure the chip temperature. This extension provides an iio interface for these adc channels. Since it is not wasting much resources and is very straightforward, we simply provide all other adc channels as optional iio interfaces as weel. This can be used for debugging or special applications. This patch also splits the tsc2007 driver in several source files: tsc2007.h -- constants, structs and stubs tsc2007_core.c -- functional parts of the original driver tsc2007_iio.c -- the optional iio stuff Makefile magic allows to conditionally link the iio stuff if CONFIG_IIO=y or =m in a way that it works with CONFIG_TOUCHSCREEN_TSC2007=m.

Input: tsc2007 - check for presence and power down tsc2007 during probe

2017-02-17T21:21:47Z

1. check if chip is really present and don't succeed if it isn't. 2. if it succeeds, power down the chip until accessed Signed-off-by: H. Nikolaus Schaller Signed-off-by: Dmitry Torokhov

Input: drop owner assignment from i2c_driver

2015-07-17T23:57:00Z

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dmitry Torokhov

This simplifies error handling path and allows us get rid of tsc2007_remove(). Tested-by: Denis Carikli Signed-off-by: Dmitry Torokhov

Input: tsc2007 - remove unused poll_delay from platform data

2013-11-26T02:27:54Z

The driver does not use poll_delay parameter, so let's remove it. Tested-by: Denis Carikli Signed-off-by: Dmitry Torokhov
