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

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

Pull staging driver updates from Greg KH: "Here's the big, really big, staging tree patches for 4.2-rc1. Loads of stuff in here, almost all just coding style fixes / churn, and a few new drivers as well, one of which I just disabled from the build a few minutes ago due to way too many build warnings.

iio: adc: ti_am335x_adc: make sample delay, open delay, averaging DT parameters

2015-05-13T17:37:22Z

Add optional DT properties to set open delay, sample delay and number of averages per sample for each adc step. Open delay, sample delay and averaging are some of the parameters that affect the sampling rate and accuracy of the sample. Making these parameters configurable via DT will help in balancing speed vs accuracy. Signed-off-by: Vignesh R Signed-off-by: Jonathan Cameron

Input: add support for ChipOne icn8318 based touchscreens

Input: touchscreen DT binding - add touchscreen-swapped-x-y property

2015-03-24T18:27:31Z

On devices with a native portrait screen a landscape touchscreen / digitizer may be used, this happens e.g. on ebook readers. In this case the X and Y axis of the touchscreen are swapped compared to the screen. Add a touchscreen-swapped-x-y property which drivers can use to see if they need to swap the axis to make the touchscreen coordinates match the screen coordinates.
