From: Jan Kiszka <jan.kiszka@siemens.com> Add the DT entry for a watchdog based on RTI1. On SR1.0 silicon, it requires additional firmware on the MCU R5F cores to handle the expiry, e.g. https://github.com/siemens/k3-rti-wdt. As this firmware will also lock the power domain to protect it against premature shutdown, mark it shared. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
