Hi, The imx6ul-evk uses a MC34901 CAN transceiver and the STB pin (standby_ needs to be controlled (1 = standby, 0 = normal mode) As far as I can see, there is no support for the STB pin currently in he can framework. What would be the correct way to describe it in the devicetree? Would it be acceptable to use something like this? https://pastebin.com/raw/SsY6USdT Or any other idea? I can give a try to add this support after we reach a conclusion for the approach. Thanks, Fabio Estevam
