5 - compatible: Must be a "<manufacturer>,<model>" pair. The following <model>
6 values are supported (assuming "atmel" as manufacturer):
31 If <manufacturer> is not "atmel", then a fallback must be used
32 with the same <model> and "atmel" as manufacturer.
35 compatible = "microchip,24c128", "atmel,24c128";
37 Supported manufacturers are:
47 Some vendors use different model names for chips which are just
48 variants of the above. Known such exceptions are listed below:
50 "nxp,se97b" - the fallback is "atmel,24c02",
51 "renesas,r1ex24002" - the fallback is "atmel,24c02"
52 "renesas,r1ex24128" - the fallback is "atmel,24c128"
53 "rohm,br24t01" - the fallback is "atmel,24c01"
55 - reg: The I2C address of the EEPROM.
59 - pagesize: The length of the pagesize for writing. Please consult the
60 manual of your device, that value varies a lot. A wrong value
61 may result in data loss! If not specified, a safety value of
62 '1' is used which will be very slow.
64 - read-only: This parameterless property disables writes to the eeprom.
66 - size: Total eeprom size in bytes.
68 - no-read-rollover: This parameterless property indicates that the
69 multi-address eeprom does not automatically roll over
70 reads to the next slave address. Please consult the
71 manual of your device.
73 - wp-gpios: GPIO to which the write-protect pin of the chip is connected.
75 - address-width: number of address bits (one of 8, 16).
80 compatible = "atmel,24c32";
83 wp-gpios = <&gpio1 3 0>;
