1Maxim Integrated MAX2175 RF to Bits tuner 2----------------------------------------- 3 4The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with 5RF to Bits® front-end designed for software-defined radio solutions. 6 7Required 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 16Optional 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 34Example: 35-------- 36 37Board specific DTS file 38 39/* Fixed XTAL clock node */ 40maxim_xtal: clock { 41 compatible = "fixed-clock"; 42 #clock-cells = <0>; 43 clock-frequency = <36864000>; 44}; 45 46/* A tuner device instance under i2c bus */ 47max2175_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};
