Input: goodix - fix touch coordinates on WinBook TW100 and TW700

2015-07-24T16:11:02+00:00

The touchscreen on the WinBook TW100 and TW700 don't match the default display, with 0,0 touches being reported when touching at the bottom right of the screen. 1280,800 0,800 +-------------+ | | | | | | +-------------+ 1280,0 0,0 It's unfortunately impossible to detect this problem with data from the DSDT, or other auxiliary metadata, so fallback to quirking this specific model of tablet instead.

Input: drop owner assignment from i2c_driver

2015-07-17T23:57:00+00:00

i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Dmitry Torokhov

Input: goodix - do not explicitly set evbits in input device

2015-06-11T23:47:34+00:00

input_mt_init_slots() will do that for us. Reviewed-by: Benjamin Tissoires Acked-by: Bastien Nocera Signed-off-by: Dmitry Torokhov

Input: goodix - export id and version read from device

2015-06-09T18:23:27+00:00

Goodix touchscreens export through their registers a Product ID and Firmware Version. The Product ID is an ASCII encoding of the product name (e.g.: "911"). Export to sysfs (through the input subsystem) the product id and firmware version read from the device rather than using constant values.

Input: goodix - fix variable length array warning

2015-06-09T18:23:26+00:00

Fix sparse warning: drivers/input/touchscreen/goodix.c:182:26: warning: Variable length array is used. Replace the variable length array with fixed length. Some Goodix devices have maximum 5 touch points, while others have 10 touch points. Using the maximum length (80 bytes) for all devices will lead to wasting 40 bytes on stack when using devices with maximum 5 touch points. However, that is preferable to using kmalloc which will use even more resources. Signed-off-by: Irina Tirdea Acked-by: Bastien Nocera Signed-off-by: Dmitry Torokhov

Input: goodix - check the 'buffer status' bit before reading data

2015-05-06T23:54:25+00:00

The MSB of the first byte read via I2C at the coordinates address indicates whether the data is valid or ready (called "buffer status" in the datasheets) when an interrupt is raised. Previously, this bit was ignored, which resulted in a lot of incorrect detections of "finger removed" events. Signed-off-by: Paul Cercueil Acked-by: Bastien Nocera Signed-off-by: Dmitry Torokhov
