3Required properties:
4
5 - compatible : should be "<manufacturer>,<type>", like these:
6
7 "atmel,24c00", "atmel,24c01", "atmel,24c02", "atmel,24c04",
8 "atmel,24c08", "atmel,24c16", "atmel,24c32", "atmel,24c64",
9 "atmel,24c128", "atmel,24c256", "atmel,24c512", "atmel,24c1024"
10
11 "catalyst,24c32"
12
13 "ramtron,24c64"
14
15 "renesas,r1ex24002"
16
17 If there is no specific driver for <manufacturer>, a generic
18 driver based on <type> is selected. Possible types are:
19 "24c00", "24c01", "24c02", "24c04", "24c08", "24c16", "24c32", "24c64",
20 "24c128", "24c256", "24c512", "24c1024", "spd"
21
22 - reg : the I2C address of the EEPROM
23
24Optional properties:
25
26 - pagesize : the length of the pagesize for writing. Please consult the
27 manual of your device, that value varies a lot. A wrong value
28 may result in data loss! If not specified, a safety value of
29 '1' is used which will be very slow.
30
31 - read-only: this parameterless property disables writes to the eeprom
32
33Example:
34
35eeprom@52 {
36 compatible = "atmel,24c32";
37 reg = <0x52>;
38 pagesize = <32>;
39};
