embedded linux - touchscreen ft5x06 not responding? -

-

i using kontron smarc-samx6i board run nxp imx6q processor. working yocto in need interface touch screen of ft5316 through i2c . edited device tree follows:

polytouch: edt_ft5x06@39 {          compatible = "edt","edt_ft5x06","edt-ft5x06";          reg = <0x39>;          pinctrl-names = "default";          pinctrl-0 = <&pinctrl_smx6_i2c_gpio_1>;          irq_pin=<&gpio3 1 0>;          interrupt-parent = <&gpio3>;          interrupts = <0 70 0x04>; };

when using i2cdump command touchscreen responds successfully, when working module won't respond.

when using below command getting following output

root@smarc-samx6i:~# cat /proc/bus/input/devices i: bus=0019 vendor=0001 product=0001 version=0100  n: name="gpio-keys.27"  p: phys=gpio-keys/input0  s: sysfs=/devices/soc0/gpio-keys.27/input/input0  u: uniq=  h: handlers=kbd event0 evbug  b: prop=0  b: ev=23  b: key=4000 100000 0 0 0  b: sw=1

my device did not probe , not getting error while instantiating device using command:

echo edt_ft5x06 0x39> /sys/bus/i2c/devices/i2c-1/new_device instantiated device edt_ft5x06 @ 0x39 device

how can make work!!

i assume "when working module won't respond" mean won't respond touch events on touchscreen. did driver module correctly load? built-in or used loadable module? did check "dmesg" confirming driver loaded or output of lsmod? if driver loaded properly, getting interrupts?

what output of "cat /proc/interrupts"? see interrupt requests increasing when press touchscreen? if not then, have problem interrupts. if see interrupts, can check utility "evtest" see if touchscreen events?
