Hello there, I am trying to create a dts file for an 8 buttons keyboard. The pins I am using are: P8_35, P8_36, P8_39, P8_40, P8_41, P8_42, P8_43, P8_44
HDMI is turned off. Using Dereks molloy book, I have found an example dts file for P9_15 key: https://pastebin.com/kKp3ji7s There are 2 main parts for me: pinctrl-single,pins = < 0x040 0x37 // P9_15 pull-up mode 7 GPIO1_16 This first one is quite straight forward for me, I have chnaged it to my needs: pinctrl-single,pins = < 0x0d0 0x37 // P8_35 pull-up mode 7 0x0c8 0x37 // P8_36 pull-up mode 7 0x0b8 0x37 // P8_39 pull-up mode 7 0x0bc 0x37 // P8_40 pull-up mode 7 0x0b0 0x37 // P8_41 pull-up mode 7 0x0b4 0x37 // P8_42 pull-up mode 7 0x0a8 0x37 // P8_43 pull-up mode 7 0x0ac 0x37 // P8_44 pull-up mode 7 The problem is I dont know how to config this part: button_P9_15 { debounce_interval = <50>; linux,code = <28>; label = "button9_15"; gpios = <&gpio2 16 0x1>; gpio-key,wakeup; autorepeat; I dont know how to interpret "gpios = <&gpio2 16 0x1>;". I Think that 16 0x1 stands for Gpio1[16], but I dont know what does &gpio2 stands for. Please correct me if I am wrong. What would be the configuration for the P8_44 button? I tried "gpios = <&gpio2 9 0x2>;" but that did not work. The overlay loaded but the button doesnt work. It is wired correctly though. I Would aprichiate all help. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
