@@ -583,3 +583,25 @@ Why: Superseded by the UVCIOC_CTRL_QUERY ioctl.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.
+Who: Hans Verkuil <hans.verkuil@cisco.com>
