@ -583,3 +583,25 @@ Why: Superseded by the UVCIOC_CTRL_QUERY ioctl.
|
||||
Who: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
|
||||
|
||||
----------------------------
|
||||
|
||||
What: For VIDIOC_S_FREQUENCY the type field must match the device node's type.
|
||||
If not, return -EINVAL.
|
||||
When: 3.2
|
||||
Why: It makes no sense to switch the tuner to radio mode by calling
|
||||
VIDIOC_S_FREQUENCY on a video node, or to switch the tuner to tv mode by
|
||||
calling VIDIOC_S_FREQUENCY on a radio node. This is the first step of a
|
||||
move to more consistent handling of tv and radio tuners.
|
||||
Who: Hans Verkuil <hans.verkuil@cisco.com>
|
||||
|
||||
----------------------------
|
||||
|
||||
What: Opening a radio device node will no longer automatically switch the
|
||||
tuner mode from tv to radio.
|
||||
When: 3.3
|
||||
Why: Just opening a V4L device should not change the state of the hardware
|
||||
like that. It's very unexpected and against the V4L spec. Instead, you
|
||||
switch to radio mode by calling VIDIOC_S_FREQUENCY. This is the second
|
||||
and last step of the move to consistent handling of tv and radio tuners.
