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>;
};
};
};
