So do I need some kernel module for this with the mainline kernel
loaded? I don't have eeprom listed under 0-0050.

I also see eeprom only for am335x-pocketbeagle.dts and
am57xx-beagle-x15-common.dtsi so maybe it should be justd added?

I guess this could be checked with i2cget command too meanwhile.

Regards,

Tony
