| 604 | What: For VIDIOC_S_FREQUENCY the type field must match the device node's type. | ||
| 605 | If not, return -EINVAL. | ||
| 606 | When: 3.2 | ||
| 607 | Why: It makes no sense to switch the tuner to radio mode by calling | ||
| 608 | VIDIOC_S_FREQUENCY on a video node, or to switch the tuner to tv mode by | ||
| 609 | calling VIDIOC_S_FREQUENCY on a radio node. This is the first step of a | ||
| 610 | move to more consistent handling of tv and radio tuners. | ||

| 615 | What: Opening a radio device node will no longer automatically switch the | ||
| 616 | tuner mode from tv to radio. | ||
| 617 | When: 3.3 | ||
| 618 | Why: Just opening a V4L device should not change the state of the hardware | ||
| 619 | like that. It's very unexpected and against the V4L spec. Instead, you | ||
| 620 | switch to radio mode by calling VIDIOC_S_FREQUENCY. This is the second | ||
| 621 | and last step of the move to consistent handling of tv and radio tuners. | ||
