* Input: edt-ft5x06 - do not hardcode interrupt trigger typeDmitry Torokhov2015-09-281-1/+1
| | | | | | | | | | Instead of hardcoding IRQ trigger type to IRQF_TRIGGER_FALLING, let's respect settings specified in device tree. To be compatible with older DTSes, if trigger type is not set up in DTS we'll set it to default (falling edge).

* Input: edt-ft5x06 - switch to newer gpio frameworkFranklin S Cooper Jr2015-09-281-2/+2
| | | | | | | | | | | | | | | The current/old gpio framework used doesn't properly listen to ACTIVE_LOW and ACTIVE_HIGH flags. The newer gpio framework takes into account these flags when setting gpio values. Since the values being output were based on voltage and not logic they change to reflect this difference. Also use gpiod_set_value_cansleep since wake and reset pins can be provided by bus based io expanders. Switch from msleep(5) to udelay_range(5000,6000) to avoid check patch warning.

* Input: zforce - make the interrupt GPIO optionalDirk Behme2015-08-031-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for hardware which uses an I2C Serializer / Deserializer (SerDes) to communicate with the zFroce touch driver. In this case the SerDes will be configured as an interrupt controller and the zForce driver will have no access to poll the GPIO line. To support this, we add two dedicated new GPIOs in the device tree: reset-gpios and irq-gpios, with the irq-gpios being optional. To not break the existing device trees, the index based 'gpios' entries are still supported, but marked as deprecated. With this, if the interrupt GPIO is available, either via the old or new device tree style, the while loop will read and handle the packets as long as the GPIO indicates that the interrupt is asserted (existing, unchanged driver behavior). If the interrupt GPIO isn't available, i.e. not configured via the new device tree style, we are falling back to one read per ISR invocation (new behavior to support the SerDes). Note that the gpiod functions help to handle the optional GPIO: devm_gpiod_get_index_optional() will return NULL in case the interrupt GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too, by returning 0 in this case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Testing has revealed that the temperature in the rtp controller of the A10 (sun4i) SoC has a different curve then on the A13 (sun5i) and later models. Add a new sun5i-a13-ts compatible to differentiate the newer models and set the curve based on the compatible string. The new curve is still not ideal on all A10-s, that seems to have to do with there being a large spread between different A10-s out there, the new curve us based on callibration results on 4 completely different models: raw min raw max temp min temp max stepsize offset Tong Zhang's hackberry 2402 2680 45.0 80.0 0.125 -255.3 Hansg's Cubieboard 2207 2300 36.0 45.0 0.096 -175.8 Olliver's lime 1 (*): 2258 2537 48.3 87.1 0.139 -265.7 Olliver's lime 2 (*): 2222 2486 46.7 91.7 0.170 -331.0 *) from: http://linux-sunxi.org/Temperature_Calibration Average all 4: 0.133 -257.0 Average without outliers (middle 2): 0.132 -261.0 Since it is better to slightly overreport the temperature this patch uses the average of all 4 as curve.

| | | | | | | | | | | | | | | | | | | 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.

* | | | Input: auo_pixcir_ts - add devicetree supportHeiko Stübner2013-02-251-0/+30
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the necessary code to create the needed platformdata from devicetree informations. The interrupt mode of the chip is not set via devicetree, as it is not a property of the hardware but instead only a preferred type of operation. This should probably be made settable via configfs in the future. The option set as default is the mode the datasheet mentions as default.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the STMPE Touchscreen driver to be successfully probed and initialised when Device Tree support is enabled. Bindings are mentioned in Documentation too.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework and don't support this API anymore. The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init.
