Patch 1 adds the missing #address-cells and #size-cells properties for all I2C controllers. These had gone unnoticed since no I2C clients had been added so far. Patch 2 ensures the I2C controllers are consistently named (and their names correspond to those find in various documents) by adding aliases to them. The module and system EEPROMs found on most modern Jetson devices are added in patches 3 and 4. Finally, the thermal sensor found on the Jetson AGX Thor module is described in patch 5. This allows reading the local temperature of the module.
