Those on the expansion header X16 could be named via gpio-line-name this makes it easier to access via libgpiod. Also there seems to be LEDs and switches on the phyBOARD. Best regards

Hello Stefan, > According to the documentation there are GPIOs accessible. Those on the > expansion header X16 could be named via gpio-line-name this makes it > easier to access via libgpiod. Also there seems to be LEDs and switches > on the phyBOARD. I will add gpio-line-name for the two accessible GPIOs on X16 that are not mapped to specific functions. I will also add the heartbeat LED that is located on the SoM. Regarding the two switches on the phyBOARD, they reset the CPU and the board so I am not sure that they can have an entry in the device tree. Thanks, Mathieu
