   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.

  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         };
