2015-07-11	Input: of_touchscreen - switch to using device properties	Dmitry Torokhov	1	-26/+30
	Let's switch form OF to device properties so that common parsing code could work not only on device tree but also on ACPI-based platforms. Reviewed-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-07-11	Input: of_touchscreen - fix setting max values on X/Y axis	Dmitry Torokhov	1	-4/+6
	The binding specification says that "touchscreen-size-x" and "-y" specify horizontal and vertical resolution of the touchscreen and therefore maximum absolute coordinates should be reduced by 1 since we are starting with 0.

2015-07-11	Input: of_touchscreen - always issue warning if axis is not set up	Dmitry Torokhov	1	-7/+3
	Do issue warning about axis that is present in device tree but not specified by the driver even in case of multi-touch axis as callers now tell us if they expect multi-touch data or not. Reviewed-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-06-25	Input: improve parsing OF parameters for touchscreens	Dmitry Torokhov	1	-25/+44
	When applying touchscreen parameters specified in device tree let's make sure we keep whatever setup was done by the driver and not reset the missing values to zero.

2015-03-24	Input: of_touchscreen - register multitouch axes	Maxime Ripard	1	-5/+17
	So far, the DT parsing code was only setting up the regular input axes, completely ignoring their multitouch counter parts. Fill them with the same parameters than the regular axes.

2015-03-24	Input: of_touchscreen - rework the DT parsing function	Maxime Ripard	1	-10/+40
	The DT parsing function currently duplicates a lot of the code to parse the touchscreen DT properties. In order to ease further additions to this parsing routine, rework it slightly to create new helper functions.

2014-05-29	Input: add common DT binding for touchscreens	Sebastian Reichel	1	-0/+45
	Add common DT binding documentation for touchscreen devices and implement input_parse_touchscreen_of_params, which parses the common properties and configures the input device accordingly. The method currently does not interpret the axis inversion properties, since there is no matching flag in the generic linux input device.
