Hi, I've got a question regarding how to handle I2C eeprom devices. I see that in the kernel/drivers/misc/eeprom there are not that many drivers available. Does it mean that they support various chips that do not necessarily come from one vendor? Looking at example at24.c, in the compatible properties I see that all of them refers to atmel, however when I compared the following devices: AT24C04C and BRCB008GWZ, at the first glance they look kinda similar: - they are organized internally in the same way - 1024 x 8 (8K) - read/write commands looks the same
I'm not asking you to tell me whether or not it's possible this driver at24 with the device I need (BRCB008GWZ), rather I would like to get a suggestion on how to approach this and what factors I should take into account to make the right decision.
Best regards Patryk
