This restores support for IOT2050 by widely synchronizing its DT files with the Linux kernel. We additionally need to add the alias restoration that is still waiting for its upstream merge and the not-yet-upstreamed bits needed for watchdog reboot detection. Fixes: 4dbdc84754ea ("arm: dts: k3-am654: pull in dtb update from Linux") Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
