Dsi4713.rst32 The I2C device driver exports a v4l2-subdev interface to the kernel.
33 All properties can also be accessed by v4l2 extended controls interface, by
34 using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
36 The platform device driver exports a v4l2 radio device interface to user land.
40 Applications can use v4l2 radio API to specify frequency of operation, mute state,
43 When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
48 The properties can be accessed using v4l2 extended controls.
49 Here is an output from v4l2-ctl util:
53 / # v4l2-ctl -d /dev/radio0 --all -L
182 Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
