----------------------------
-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
class is added.
-Differences from the Spec
-=========================
-
-There are a few places where the framework acts slightly differently from the
-V4L2 Specification. Those differences are described in this section. We will
-have to see whether we need to adjust the spec or not.
-
-1) It is no longer required to have all controls contained in a
-v4l2_ext_control array be from the same control class. The framework will be
-able to handle any type of control in the array. You need to set ctrl_class
-to 0 in order to enable this. If ctrl_class is non-zero, then it will still
-check that all controls belong to that control class.
-
-If you set ctrl_class to 0 and count to 0, then it will only return an error
-if there are no controls at all.
-
-2) Clarified the way error_idx works. For get and set it will be equal to
-count if nothing was done yet. If it is less than count then only the controls
-up to error_idx-1 were successfully applied.
