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.

55 remote-endpoint = <&slave_rx_device>;
56 };
57 };
