Maxim Integrated MAX2175 RF to Bits tuner
|
|
-----------------------------------------
|
|
|
|
The MAX2175 IC is an advanced analog/digital hybrid-radio receiver with
|
|
RF to Bits® front-end designed for software-defined radio solutions.
|
|
|
|
Required properties:
|
|
--------------------
|
|
- compatible: "maxim,max2175" for MAX2175 RF-to-bits tuner.
|
|
- clocks: clock specifier.
|
|
- port: child port node corresponding to the I2S output, in accordance with
|
|
the video interface bindings defined in
|
|
Documentation/devicetree/bindings/media/video-interfaces.txt. The port
|
|
node must contain at least one endpoint.
|
|
|
|
Optional properties:
|
|
--------------------
|
|
- maxim,master : phandle to the master tuner if it is a slave. This
|
|
is used to define two tuners in diversity mode
|
|
(1 master, 1 slave). By default each tuner is an
|
|
individual master.
|
|
- maxim,refout-load : load capacitance value (in picofarads) on reference
|
|
output drive level. The possible load values are:
|
|
0 (default - refout disabled)
|
|
10
|
|
20
|
|
30
|
|
40
|
|
60
|
|
70
|
|
- maxim,am-hiz-filter : empty property indicates the AM Hi-Z filter is used
|
|
in this hardware for AM antenna input.
|
|
|
|
Example:
|
|
--------
|
|
|
|
Board specific DTS file
|
|
|
|
/* Fixed XTAL clock node */
|
|
maxim_xtal: clock {
|
|
compatible = "fixed-clock";
|
|
#clock-cells = <0>;
|
|
clock-frequency = <36864000>;
|
|
};
|
|
|
|
/* A tuner device instance under i2c bus */
|
|
max2175_0: tuner@60 {
|
|
compatible = "maxim,max2175";
|
|
reg = <0x60>;
|
|
clocks = <&maxim_xtal>;
|
|
maxim,refout-load = <10>;
|
|
|
|
port {
|
|
max2175_0_ep: endpoint {
|
|
remote-endpoint = <&slave_rx_device>;
|
|
};
|
|
};
|
|
|
|
};
