28 | * chips, we'll just pass throuth the v4l ioctl structs (v4l2 not |

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! :) |
