Hi all, I have a (probably dumb) question regarding the access to the MPC5200B's timer gpio's. I added e.g.
ti...@640 { // General Purpose Timer 4 compatible = "fsl,mpc5200b-gpt","fsl,mpc5200-gpt"; reg = <0x640 0x10>; interrupts = <1 13 0>; interrupt-parent = <&mpc5200_pic>; gpio-controller; #gpio-cells = <2>; }; in the DTS file to several timers. Several gpiochipxxx folders are now present in /sys/class/gpio/. In my code, I grab the node by calling of_find_node_by_path("/soc5...@f0000000/ti...@640"), which returns the proper node. Then I try to get the gpio number (for a call to gpio_set_value()) by calling of_get_gpio(node, 0) with the node found above. However, this call always dumps of_get_gpio_flags: can't parse gpios property of_get_gpio_flags exited with status -2 What would be the proper way to determine the gpio number for a timer's gpio pin from the node name or path? Thanks for any help, Albrecht. Es weihnachtet sehr!
