Add the new compatible "microchip,24aa02e48" to accommodate 24AA02E48, the 24AA02E48 is a 2K I2C Serial EEPROM with pre-programmed globally unique, 48-bit node address, and 8-byte page size.

Applied to u-boot/master, thanks!
Add the new compatible "atmel,24mac402" to accommodate AT24MAC402. The AT24MAC402 is a 2K Serial EEPROM and the 2-Kbit memory array is internally organized as 16 pages of 16 bytes of EEPROM each. The 48-bit EUI address in the AT24MAC402 are located in the extended memory block.

How does this work in the kernel? Grepping around on what we list currently even, I see that Documentation/devicetree/bindings/eeprom/eeprom.txt lists some of the ones we have in drivers/misc/i2c_eeprom.c as an example but nothing catching on the compatible string. Does the kernel have some smart logic to match these compatibles? If so, could we mirror that? Thanks!
Hi,
Can be accepted?
