Maxim Integrated MAX2175 RF to Bits tuner

The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with
RF to Bits® 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>;
    };
};

};
