1 | EEPROMs (I2C) | ||
2 | |||
3 | Required properties: | ||
4 | |||
5 | - compatible : should be "<manufacturer>,<type>" | ||
6 | If there is no specific driver for <manufacturer>, a generic | ||
7 | driver based on <type> is selected. Possible types are: | ||
8 | 24c00, 24c01, 24c02, 24c04, 24c08, 24c16, 24c32, 24c64, | ||
9 | 24c128, 24c256, 24c512, 24c1024, spd | ||
10 | |||
11 | - reg : the I2C address of the EEPROM | ||
12 | |||
13 | Optional properties: | ||
14 | |||
15 | - pagesize : the length of the pagesize for writing. Please consult the | ||
16 | manual of your device, that value varies a lot. A wrong value | ||
17 | may result in data loss! If not specified, a safety value of | ||
18 | '1' is used which will be very slow. | ||
19 | |||
20 | - read-only: this parameterless property disables writes to the eeprom | ||
21 | |||
22 | Example: | ||
23 | |||
24 | eeprom@52 { | ||
25 | compatible = "atmel,24c32"; | ||
26 | reg = <0x52>; | ||
27 | pagesize = <32>; | ||
28 | }; | ||
