H A Dsi4713.rst34 The I2C device driver exports a v4l2-subdev interface to the kernel.
35 All properties can also be accessed by v4l2 extended controls interface, by
36 using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
38 The platform device driver exports a v4l2 radio device interface to user land.
42 Applications can use v4l2 radio API to specify frequency of operation, mute state,
45 When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
50 The properties can be accessed using v4l2 extended controls.
51 Here is an output from v4l2-ctl util:
55 / # v4l2-ctl -d /dev/radio0 --all -L
184 Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
