But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table. Signed-off-by: Javier Martinez Canillas Reviewed-by: Geert Uytterhoeven --- Changes in v5: - Only replace atmel variant but keep other EEPROM vendors (Geert Uytterhoeven). Changes in v4: - Only use the atmel manufacturer in the compatible string instead of keeping the deprecated ones (Rob Herring). Changes in v3: - Add Geert Uytterhoeven reviewed-by tag.
