需要使用 cypress touch IC
一直遇到障礙

請求協助.

下方是與 cypress 相關的code
PS1: synaptics 一併附在下方
PS2: synaptics function ok.

請問
為甚麼  INT 與 RST設定不同腳位? error message 卻顯示相同????

setting
                     cy,irq_gpio = <&gpio8 GPIO_A7>;
                     cy,rst_gpio = <&gpio8 GPIO_A6>;

error message:
cyttsp6_init: INIT CYTTSP RST gpio=3 and IRQ gpio=3 ERR gpio=0
