Improve the binding descriptions for the atmel,at24 and atmel,at25 EEPROM compatibles. These compatibles work for a number of different EEPROM families manufactured by vendors other than Atmel. Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>

I2C EEPROMs compatible with Atmel's AT24 family
|
|
|
|
There are multiple vendors manufacturing I2C EEPROMs compatible with the programming model of the
|
|
Atmel AT24.
|
|
|
|
Examples of compatible EEPROM families:
|
|
- Microchip AT24xxx
|
|
- ST M24xxx
|
|
|
|
Each of these can be represented by a set of common parameters (EEPROM size, page size, address
|
|
width, and timeout) available from the datasheet of the specific EEPROM. The compatible string for
|
|
these can list the specific EEPROM vendor and model along with the vendor EEPROM family as long as
|
|
the least-specific compatible entry is "atmel,at24".
|
|
|
|
Example devicetree node describing a ST M24M01 EEPROM on the i2c0 bus:
|
|
|
|
&i2c0 {
|
|
status = "okay";
|
|
clock-frequency = <I2C_BITRATE_FAST>;
|
|
|
|
eeprom@56 {
|
|
compatible = "st,m24m01", "st,m24xxx", "atmel,at24";
|
|
reg = <0x56>;
|
|
size = <DT_SIZE_K(128)>;
|
|
pagesize = <256>;
|
|
address-width = <16>;
|
|
timeout = <5>;
|
|
};
|
|
};
|
|
|
|
compatible: "atmel,at24"
