-EEPROMs (SPI) compatible with Atmel at25.
-
-Required properties:
-- compatible : Should be "<vendor>,<type>", and generic value "atmel,at25".
- Example "<vendor>,<type>" values:
- "anvo,anv32e61w"
- "microchip,25lc040"
- "st,m95m02"
- "st,m95256"
-
-- reg : chip select number
-- spi-max-frequency : max spi frequency to use
-- pagesize : size of the eeprom page
-- size : total eeprom size in bytes
-- address-width : number of address bits (one of 8, 9, 16, or 24).
- For 9 bits, the MSB of the address is sent as bit 3 of the instruction
- byte, before the address byte.
-
-Optional properties:
-- spi-cpha : SPI shifted clock phase, as per spi-bus bindings.
-- spi-cpol : SPI inverse clock polarity, as per spi-bus bindings.
-- read-only : this parameter-less property disables writes to the eeprom
-- wp-gpios : GPIO to which the write-protect pin of the chip is connected
-
-Obsolete legacy properties can be used in place of "size", "pagesize",
-"address-width", and "read-only":
-- at25,byte-len : total eeprom size in bytes
-- at25,addr-mode : addr-mode flags, as defined in include/linux/spi/eeprom.h
-- at25,page-size : size of the eeprom page
-
-Additional compatible properties are also allowed.
-
-Example:
- eeprom@0 {
- compatible = "st,m95256", "atmel,at25";
- reg = <0>
- spi-max-frequency = <5000000>;
- spi-cpha;
- spi-cpol;
- wp-gpios = <&gpio1 3 0>;
-
- pagesize = <64>;
- size = <32768>;
- address-width = <16>;
- };
