Refer to patch https://patchwork.kernel.org/project/timestamp/patch/20230214115553.10416-3-dipenp@xxxxxxxxxx/ which has compatible properties added and also code changes to reflect addition/deletion of some properties. I am not sure I have understood about ABI break comment. How else one should handle if there is no related gpio controller property found? I am assuming you are referring to the below code from the patch 2 (link above) when you said "return -ENODEV". - hte_dev->c = gpiochip_find("tegra194-gpio-aon", - tegra_get_gpiochip_from_name); + gpio_ctrl = of_parse_phandle(dev->of_node, + "nvidia,gpio-controller", 0); + if (!gpio_ctrl) { + dev_err(dev, "gpio controller node not found\n"); + return -ENODEV; + } + + hte_dev->c = gpiochip_find(gpio_ctrl, + tegra_get_gpiochip_from_of_node) > > > Best regards, > Krzysztof >
