Input: ti_am335x_tsc - read charge delay from DT

2015-02-03T19:50:38Z

This patch reads charge delay from tsc DT node and writes to REG_CHARGEDELAY register. If the charge delay is not specified in DT then default value of 0x400(CHARGEDLY_OPENDLY) is used. Signed-off-by: Vignesh R Signed-off-by: Dmitry Torokhov

Input: sun4i-ts - add support for touchpanel controller on A31

2015-01-27T07:58:56Z

The Allwinner A31 SoC (sun6i) has the same resistive touchpanel controller as on other sunxi platforms. The only difference between the variants is the control bits for enabling operations are left-shifted by 1 on the A31. Also update the comment for the original temperature sensor with information from Allwinner. Signed-off-by: Chen-Yu Tsai Signed-off-by: Dmitry Torokhov

Input: sun4i-ts - add thermal zone sensor support

2015-01-18T08:10:27Z

The touchscreen controller has a temperature sensor embedded in the SoC, which already has hwmon support in the driver. Add DT thermal zone support so we can use it with cpufreq for thermal throttling. This also adds a comment stating that we do not know the actual formula for calculating the temperature.

Input: pixcir_i2c_ts - add device tree support

2014-07-28T17:26:18Z

Provide device tree support and binding information. Also provide support for a new chip "pixcir_tangoc". Signed-off-by: Roger Quadros Signed-off-by: Dmitry Torokhov

Input: zforce - add regulator handling

2014-07-21T17:28:53Z

It's possible that the controller has an individually switchable power supply. Therefore add support to control a supplying regulator. As this is not always the case, the regulator is requested as optional. Signed-off-by: Heiko Stuebner Signed-off-by: Dmitry Torokhov

Input: tsc2005 - add DT support

2014-05-29T07:06:00Z

This adds DT support to the tsc2005 touchscreen driver. It also adds regulator support to the driver if booted via DT. Reviewed-by: Pavel Machek Acked-by: Aaro Koskinen Signed-off-by: Sebastian Reichel Signed-off-by: Dmitry Torokhov

Input: add common DT binding for touchscreens

2014-05-29T07:05:59Z

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.

Input: sun4i-ts - add support for temperature sensor

2014-05-14T23:40:06Z

The sun4i resisitive touchscreen controller also comes with a built-in temperature sensor. This commit adds support for it. This commit also introduces a new "ts-attached" device-tree property, when this is not set, the input part of the driver won't register. This way the internal temperature sensor can be used to measure the SoC temperature independent of there actually being a touchscreen attached to the controller.

Input: add driver for Allwinner sunxi SoC's rtp controller

2014-05-14T23:40:06Z

Note the sun4i-ts controller is capable of detecting a second touch, but when a second touch is present then the accuracy becomes so bad the reported touch location is not useable. The original android driver contains some complicated heuristics using the aprox. distance between the 2 touches to see if the user is making a pinch open / close movement, and then reports emulated multi-touch events around the last touch coordinate (as the dual-touch coordinates are worthless). These kinds of heuristics are just asking for trouble (and don't belong in the kernel). So this driver offers straight forward, reliable single touch functionality only.
