Input: tsc2004 - add support for tsc2004

2015-11-03T22:54:22Z

This adds support for the i2c based tsc2004 touchscreen controller. Signed-off-by: Michael Welling Acked-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: edt-ft5x06 - add support for FT5506

2015-10-16T23:58:45Z

FT5506 is essentially the same as other FT5x06 devices other than supporting 10 support points. Signed-off-by: Franklin S Cooper Jr Signed-off-by: Dmitry Torokhov

Input: add support for FocalTech FT6236 touchscreen controller

2015-10-02T18:44:20Z

This adds support for the FT6x06 and the FT6x36 family of capacitive touch panel controllers, in particular the FT6236. Signed-off-by: Noralf Trønnes Signed-off-by: Dmitry Torokhov

Input: edt-ft5x06 - do not hardcode interrupt trigger type

2015-09-28T00:34:00Z

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). Tested-by: Franklin S Cooper Jr Signed-off-by: Dmitry Torokhov

Input: edt-ft5x06 - switch to newer gpio framework

2015-09-28T00:33:58Z

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: touchscreen - add imx6ul_tsc driver support

2015-09-05T18:49:33Z

Freescale i.MX6UL contains a internal touchscreen controller, this patch add a driver to support this controller. Signed-off-by: Haibo Chen Signed-off-by: Dmitry Torokhov

Input: Add touchscreen support for Colibri VF50

2015-09-05T18:11:48Z

The Colibri Vybrid VF50 module supports 4-wire touchscreens using FETs and ADC inputs. This driver uses the IIO consumer interface and relies on the vf610_adc driver based on the IIO framework. Signed-off-by: Sanchayan Maity Signed-off-by: Dmitry Torokhov

Input: zforce - make the interrupt GPIO optional

2015-08-03T21:10:10Z

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. Signed-off-by: Dirk Behme Reviewed-by: Heiko Stuebner Signed-off-by: Dmitry Torokhov

Merge tag 'v4.2-rc3' into next

2015-07-20T17:08:17Z

Sync up with Linux 4.2-rc3 to bring in infrastructure (OF) pieces.

Input: pixcir_i2c_ts - add RESET gpio

2015-07-12T00:28:27Z

The controller has a RESET pin which is usually controlled over a GPIO line. If such a GPIO is provided, perform a RESET during probe. Signed-off-by: Roger Quadros Signed-off-by: Dmitry Torokhov
