Subject: [PATCH v6 01/10] ARM: dts: aspeed: catalina: Add IO Mezz board
 thermal sensor nodes

Add thermal sensor nodes for the IO Mezzanine (IO Mezz) board in the
Catalina platform device tree. These nodes enable temperature monitoring
for the backend NIC, improving thermal management and monitoring
capabilities.
