    1 Maxim Integrated MAX2175 RF to Bits tuner
    2 -----------------------------------------
    3 
    4 The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with
    5 RF to Bits® front-end designed for software-defined radio solutions.
    6 
    7 Required properties:
    8 --------------------
    9 - compatible: "maxim,max2175" for MAX2175 RF-to-bits tuner.
   10 - clocks: clock specifier.
   11 - port: child port node corresponding to the I2S output, in accordance with
   12         the video interface bindings defined in
   13         Documentation/devicetree/bindings/media/video-interfaces.txt. The port
   14         node must contain at least one endpoint.
   15 
   16 Optional properties:
   17 --------------------
   18 - maxim,master        : phandle to the master tuner if it is a slave. This
   19                         is used to define two tuners in diversity mode
   20                         (1 master, 1 slave). By default each tuner is an
   21                         individual master.
   22 - maxim,refout-load   : load capacitance value (in picofarads) on reference
   23                         output drive level. The possible load values are:
   24                          0 (default - refout disabled)
   25                         10
   26                         20
   27                         30
   28                         40
   29                         60
   30                         70
   31 - maxim,am-hiz-filter : empty property indicates the AM Hi-Z filter is used
   32                         in this hardware for AM antenna input.
   33 
   34 Example:
   35 --------
   36 
   37 Board specific DTS file
   38 
   39 /* Fixed XTAL clock node */
   40 maxim_xtal: clock {
   41         compatible = "fixed-clock";
   42         #clock-cells = <0>;
   43         clock-frequency = <36864000>;
   44 };
   45 
   46 /* A tuner device instance under i2c bus */
   47 max2175_0: tuner@60 {
   48         compatible = "maxim,max2175";
   49         reg = <0x60>;
   50         clocks = <&maxim_xtal>;
   51         maxim,refout-load = <10>;
   52 
   53         port {
   54                 max2175_0_ep: endpoint {
   55                         remote-endpoint = <&slave_rx_device>;
   56                 };
   57         };
   58 
   59 };
