-* https://datasheets.maximintegrated.com/en/ds/MAX6675.pdf
-* https://datasheets.maximintegrated.com/en/ds/MAX31855.pdf
-
-Required properties:
-
- - compatible: must be "maxim,max6675" or one of the following:
- "maxim,max31855k", "maxim,max31855j", "maxim,max31855n",
- "maxim,max31855s", "maxim,max31855t", "maxim,max31855e",
- "maxim,max31855r"; the generic "max,max31855" is deprecated.
- - reg: SPI chip select number for the device
- - spi-max-frequency: must be 4300000
- - spi-cpha: must be defined for max6675 to enable SPI mode 1
-
- Refer to spi/spi-bus.txt for generic SPI slave bindings.
-
-Example:
-
- max31855@0 {
- compatible = "maxim,max31855k";
- reg = <0>;
- spi-max-frequency = <4300000>;
- };
