+Maxim Integrated MAX2175 RF to Bits tuner
+-----------------------------------------
+
+The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with
+RF to BitsĀ® front-end designed for software-defined radio solutions.
+
+Required properties:
+--------------------
+- compatible: "maxim,max2175" for MAX2175 RF-to-bits tuner.
+- clocks: clock specifier.
+- port: child port node corresponding to the I2S output, in accordance with
+ the video interface bindings defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt. The port
+ node must contain at least one endpoint.
+
+Optional properties:
+--------------------
+- maxim,master : phandle to the master tuner if it is a slave. This
+ is used to define two tuners in diversity mode
+ (1 master, 1 slave). By default each tuner is an
+ individual master.
+- maxim,refout-load : load capacitance value (in picofarads) on reference
+ output drive level. The possible load values are:
+ 0 (default - refout disabled)
+ 10
+ 20
+ 30
+ 40
+ 60
+ 70
+- maxim,am-hiz-filter : empty property indicates the AM Hi-Z filter is used
+ in this hardware for AM antenna input.
+
+Example:
+--------
+
+Board specific DTS file
+
+/* Fixed XTAL clock node */
+maxim_xtal: clock {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <36864000>;
+};
+
+/* A tuner device instance under i2c bus */
+max2175_0: tuner@60 {
+ compatible = "maxim,max2175";
+ reg = <0x60>;
+ clocks = <&maxim_xtal>;
+ maxim,refout-load = <10>;
+
+ port {
+ max2175_0_ep: endpoint {
+ remote-endpoint = <&slave_rx_device>;
+ };
+ };
+
+};
