From d88ca42d93cc0f8b51dce0887578920eba0cb797 Mon Sep 17 00:00:00 2001 From: Denny Harijanto Date: Mon, 4 Feb 2019 13:13:11 +0700 Subject: [PATCH 4/5] Added Parameters to Atmel TouchScreen Drivers Libinput expects both ABS_MT_TOUCH_MAJOR and ABS_MT_WIDTH_MAJOR to have proper min and max value. Without them, the input device is rejected. --- drivers/input/touchscreen/atmel_mxt1386.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/input/touchscreen/atmel_mxt1386.c b/drivers/input/touchscreen/atmel_mxt1386.c index 0ee2949edb5..6769d3a8938 100644 --- a/drivers/input/touchscreen/atmel_mxt1386.c +++ b/drivers/input/touchscreen/atmel_mxt1386.c @@ -2997,8 +2997,8 @@ static int __devinit mxt_probe(struct i2c_client *client, // multi touch input_set_abs_params(input, ABS_MT_POSITION_X, 0, mxt->pdata->max_x, 0, 0); input_set_abs_params(input, ABS_MT_POSITION_Y, 0, mxt->pdata->max_y, 0, 0); - input_set_abs_params(input, ABS_MT_TOUCH_MAJOR, 0, 0, 0, 0); - input_set_abs_params(input, ABS_MT_WIDTH_MAJOR, 0, 0, 0, 0); + input_set_abs_params(input, ABS_MT_TOUCH_MAJOR, 0, 0xff, 0, 0); + input_set_abs_params(input, ABS_MT_WIDTH_MAJOR, 0, 0xff, 0, 0); // input_set_abs_params(input, ABS_MT_TRACKING_ID, 0, MXT_MAX_NUM_TOUCHES, 0, 0); // input_set_abs_params(input, ABS_MT_PRESSURE, 0, 255, 0, 0); -- 2.19.1
