Silicon Labs FM radio device
|
||||
|
||||
-FM RX playback with RDS
|
||||
FM signal is demodulated then audio L/R samples are sent to external audio codec.
|
||||
FM Rx RDS data received sent to host processor on I2C.
|
||||
|
||||
Required Properties:
|
||||
- compatible: "silabs,silabs-fm"
|
||||
|
||||
Example:
|
||||
silabs,silabs-fm {
|
||||
compatible = "silabs,silabs-fm";
|

Silicon Labs Si4705 FM radio
|
||||
|
||||
Silabs Si4705 is a FM radio chip which sits on the i2c bus.
|
||||
This node must live under i2c controller.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible : should be "silabs,si4705"
|
||||
- reg : i2c slave address of the device
|
||||
- interrupt-parent : parent of interrupt
|
||||
- interrupts : interrupt to indicate completion of on going tune, seek etc.
|
||||
- silabs,int-gpio : interrupt gpio
|
||||
- silabs,reset-gpio : reset gpio
|
||||
- silabs,status-gpio : status gpio
|
||||
- pinctrl-names : This should be defined if a target uses pinctrl framework.
|
||||
See "pinctrl" in Documentation/devicetree/bindings/pinctrl/msm-pinctrl.txt.
|
||||
It should specify the names of the configs that pinctrl can install in driver.
|
||||
Following are the pinctrl configs that can be installed:
|
||||
"pmx_fm_active" : Active configuration of pins, this should specify active
|
||||
config defined in pin groups of interrupt and reset gpio.
|
||||
"pmx_fm_suspend" : Disabled configuration of pins, this should specify sleep
|
||||
config defined in pin groups of interrupt and reset gpio.
|
||||
|
||||
- pinctrl : Active and suspend configuration of interrupt and reset pins.
|
||||
|
||||
- interrupt-names : Name of interrupt, must be "silabs_fm_int"
|
||||
|
||||
Optional properties:
|
||||
- vdd-supply : Digital power supply needed to power device
|
||||
- va-supply : Analog power supply needed to power device
|
||||
- silabs,va-supply-voltage : specifies VA voltage levels for supply.
|
||||
Should be specified in pair (min, max), units uV.
|
||||
- silabs,vdd-supply-voltage : specifies VDD voltage levels for supply.
|
||||
Should be specified in pairs (min, max), units uV.
