I am working on khadas edge V with SDK version of 9.0. I want to register one GPIO(from 40 pin gpio header) as an interrupt pin.
I am sharing my way of doing it.
interrupt_pin : interrupt_pin
rockchip,pin = <1 50 RK_FUNC_GPIO &pcfg_pull_up>; /* GPIO1_C2 */
But I am getting an error of pinctrl registration.
So, What is wrong here? Am I missing anything?
