[PATCH 9/9] mips: dts: realtek: Add restart to Cisco SG220-26P

From: Sander Vanheule
Date: Sun Jan 19 2025 - 13:35:45 EST


Define a gpio-restart node to the Cisco SG220-26P so the device can be
rebooted using the SoC's hard reset pin. Set the priority to 192 so the
gpio-restart method takes priority over the watchdog restart.
