i.MX6UL TSC official driver

[Shio_Tamba]

Hi, 

Is there an official driver for the i.MX6UL TSC?

If so, where can I download it?

Best regards,

Here is the driver.

Thank you.

I have a question for this driver.

At line 289, 

if (!tsc_wait_detect_mode(tsc) ||
gpiod_get_value_cansleep(tsc->xnur_gpio)) {
input_report_key(tsc->input, BTN_TOUCH, 1);
input_report_abs(tsc->input, ABS_X, x);
input_report_abs(tsc->input, ABS_Y, y);
} else {
input_report_key(tsc->input, BTN_TOUCH, 0);
}

I cannot understand why gpiod_get_value_cansleep() called.

Why can checking XNUR determine that the touch was released?
