+Analog Devices AD2S1200 and AD2S1205 Resolver-to-Digital Converter
+
+Required properties:
+ - compatible : should be "adi,ad2s1200" or "adi,ad2s1205"
+ - reg : the SPI chip select number of the device
+ - sample-gpios : The GPIO pin connected to the SAMPLE line of the AD2S1200
+ - rdvel-gpios : The GPIO pin connected to the RDVEL line of the AD2S1200
+
+Example:
+
+ resolver {
+ compatible = "adi,ad2s1200";
+ reg = <4>;
+ sample-gpios = <&gpio 5 GPIO_ACTIVE_HIGH>;
+ rdvel-gpios = <&gpio 6 GPIO_ACTIVE_HIGH>;
+ };
