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
+

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
+
};
