Merge branch 'next' into for-linus

2016-01-22T01:27:27Z

Prepare second round of input updates for 4.5 merge window.

Input: gpio-keys - allow setting input device name in DT

2016-01-13T08:18:05Z

Allow specifying name if input device via device tree property. This helps userspace code to get name and perform proper event to key mapping in some cases (for example, on Android). Signed-off-by: Laxman Dewangan Signed-off-by: Dmitry Torokhov

Merge branch 'goodix' into next

2016-01-07T01:31:06Z

Merge several improvements to Goodix touchscreen driver: - power management support - configuration upload - axis swapping and inversion

Input: goodix - add axis swapping and axis inversion support

2015-12-18T01:11:55Z

Implement support for the following device-tree and ACPI 5.1 DSD properties in the goodix touchscreen driver: - touchscreen-inverted-x: X axis is inverted (boolean) - touchscreen-inverted-y: Y axis is inverted (boolean) - touchscreen-swapped-x-y: X and Y axis are swapped (boolean) These are necessary on tablets which have a display in portrait format while the touchscreen is in landscape format, such as e.g. the MSI Primo 81.

Input: goodix - reset device at init

2015-12-18T01:11:52Z

After power on, it is recommended that the driver resets the device. The reset procedure timing is described in the datasheet and is used at device init (before writing device configuration) and for power management. It is a sequence of setting the interrupt and reset pins high/low at specific timing intervals. This procedure also includes setting the slave address to the one specified in the ACPI/device tree. This is based on Goodix datasheets for GT911 and GT9271 and on Goodix driver gt9xx.c for Android (publicly available in Android kernel trees for various devices). For reset the driver needs to control the interrupt and reset gpio pins (configured through ACPI/device tree). For devices that do not have the gpio pins properly declared, the functionality depending on these pins will not be available, but the device can still be used with basic functionality. For both device tree and ACPI, the interrupt gpio pin configuration is read from the "irq-gpios" property and the reset pin configuration is read from the "reset-gpios" property. For ACPI 5.1, named properties can be specified using the _DSD section. This functionality will not be available for devices that use indexed gpio pins declared in the _CRS section (we need to provide backward compatibility with devices that do not support using the interrupt gpio pin as output). For ACPI, the pins can be specified using ACPI 5.1: Device (STAC) { Name (_HID, "GDIX1001") ... Method (_CRS, 0, Serialized) { Name (RBUF, ResourceTemplate () { I2cSerialBus (0x0014, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\I2C0", 0x00, ResourceConsumer, , ) GpioInt (Edge, ActiveHigh, Exclusive, PullNone, 0x0000, "\\I2C0", 0x00, ResourceConsumer, , ) { // Pin list 0 } GpioIo (Exclusive, PullDown, 0x0000, 0x0000, IoRestrictionOutputOnly, "\\I2C0", 0x00, ResourceConsumer, , ) { 1 } }) Return (RBUF) } Name (_DSD, Package () { ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"), Package () { Package (2) {"irq-gpios", Package() {^STAC, 0, 0, 0 }}, Package (2) {"reset-gpios", Package() {^STAC, 1, 0, 0 }}, ... } } Signed-off-by: Octavian Purdila Signed-off-by: Irina Tirdea Acked-by: Rob Herring Acked-by: Bastien Nocera Tested-by: Bastien Nocera Tested-by: Aleksei Mamlin Signed-off-by: Dmitry Torokhov

Input: add touchscreen support for TS-4800

2015-12-16T22:00:51Z

On this board, the touchscreen, an ads7843, is not handled directly by Linux but by a companion FPGA. This FPGA is memory-mapped and the IP design is very similar to the mk712. This commit adds the support for this IP. Signed-off-by: Damien Riegel Acked-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: sun4i-lradc-keys - fix typo in binding documentation

Input: pixcir_i2c - add support for wake and enable gpios

2015-12-05T01:12:07Z

On some devices the wake and enable pins of the pixcir touchscreen controller are connected to gpios and these must be controlled by the driver for the device to operate properly. Signed-off-by: Sander Vermin Signed-off-by: Hans de Goede Acked-by: Rob Herring Signed-off-by: Dmitry Torokhov
