EEPROMs (I2C)
Required properties:
- compatible : should be "<manufacturer>,<type>", like these:
"atmel,24c00", "atmel,24c01", "atmel,24c02", "atmel,24c04",
"atmel,24c08", "atmel,24c16", "atmel,24c32", "atmel,24c64",
"atmel,24c128", "atmel,24c256", "atmel,24c512", "atmel,24c1024"
"catalyst,24c32"
"microchip,24c128"
"ramtron,24c64"
"renesas,r1ex24002"
The following manufacturers values have been deprecated:
"at", "at24"
If there is no specific driver for <manufacturer>, a generic
device with <type> and manufacturer "atmel" should be used.
Possible types are:
"24c00", "24c01", "24c02", "24c04", "24c08", "24c16", "24c32", "24c64",
"24c128", "24c256", "24c512", "24c1024", "spd"
- reg : the I2C address of the EEPROM
Optional properties:
- pagesize : the length of the pagesize for writing. Please consult the
manual of your device, that value varies a lot. A wrong value
may result in data loss! If not specified, a safety value of
'1' is used which will be very slow.
- read-only: this parameterless property disables writes to the eeprom
Example:
eeprom@52 {
compatible = "atmel,24c32";
reg = <0x52>;
pagesize = <32>;
};
