28 * chips, we'll just pass throuth the v4l ioctl structs (v4l2 not
29 * yet...). It is a bit less flexible, but most/all used i2c chips

38 * NEWCHANNEL and SWITCH_MUTE are here because the MSP3400 has a special
39 * routine to go through when it tunes in to a new channel before turning
40 * back on the sound.
41 * Either SET_RADIO, NEWCHANNEL, and SWITCH_MUTE or SET_INPUT need to be
42 * implemented (MSP3400 uses SET_RADIO to select inputs, and SWITCH_MUTE for
43 * channel-change mute -- TEA6300 et al use SET_AUDIO to select input [TV,
44 * radio, external, or MUTE]). If both methods are implemented, you get a
45 * cookie for doing such a good job! :)
