There was one warning when building. Please double check your code
compiles cleanly before submitting:

arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-minerva-cmc.dts:91.24-94.4:
Warning (i2c_bus_reg):
/ahb/apb/bus@1e78a000/i2c-bus@100/temperature-sensor@4B: I2C bus unit
address format error, expected "4b"

I've fixed that and added your patch to the aspeed tree for 6.7.
