Just for my information, is the firmware and board files for this platform available in linux-firmware? Or does it leverage the files already present from the original (Android?) installation? I ask because the alternative solution suggested by Kalle would require modification of the board file on the device, and that seems more of a hassle than just modifying the DT. So I'm personally OK with this suggested approach. /jeff
