+Maxim MAX6675 thermocouple converter
+
+Required properties:
+
+ - compatible: must be "maxim,max6675"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: must be 4300000
+ - spi-cpha: SPI Mode 1.
+
+ Refer to spi/spi-bus.txt for generic SPI slave bindings
+
+Example:
+
+ max6675@0 {
+ compatible = "maxim,max6675";
+ reg = <0>;
+ spi-max-frequency = <4300000>;
+ spi-cpha;
+ };
