EEPROMs can have additional properties, so they are not suitable for trivial-devices.txt. Move most bindings to the designated eeprom.txt. Add the missing "atmel,24c08" while doing that. Note that the remaining ones in trivial-devices need to be dealt with separately because of improper manufacturer names.

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"
|
|
|
|
"ramtron,24c64"
|
|
|
|
If there is no specific driver for <manufacturer>, a generic
|
|
driver based on <type> is selected. 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>;
|
|
};
