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,
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.
185 The tool can be found in v4l-dvb repository under v4l2-apps/util directory.
