media: v4l2-ctrls: drop 'elems' argument from control type ops.

2022-09-24T06:49:06+00:00

The type ops for equal, init and validate have an elems argument,
but this can be taken from struct v4l2_ctrl: ctrl->elems for
equal and init, and ctrl->new_elems for validate (since you are
validating a new control value).

So drop this argument and update all callers.

media: v4l2-ctrls: Export default v4l2_ctrl_type_ops callbacks

2022-08-29T13:32:13+00:00

Export the callback functions of the default v4l2 control type operations
such as a driver defining its own operations could reuse some of them.

media: v4l2-ctrls: optimize type_ops for arrays

2022-08-29T13:32:13+00:00

Initializing arrays and validating or checking for equality of arrays
is suboptimal since it does this per element.

Change the ops to operate on the whole payload to speed up array
operations.

media: v4l2-ctrls: add v4l2_ctrl_modify_dimensions

2022-08-19T11:47:54+00:00

Add a new function to modify the dimensions of an array control.

This is typically used if the array size depends on e.g. the currently
selected video format.

media: v4l2-ctrls: alloc arrays in ctrl_ref

2022-08-19T11:47:00+00:00

Also allocate space for arrays in struct ctrl_ref.

This is in preparation for allowing to change the array size from
a driver.

media: v4l2-ctrls: allocate space for arrays

2022-08-19T11:46:11+00:00

Just like dynamic arrays, also allocate space for regular arrays.

This is in preparation for allowing to change the array size from
a driver.

media: uapi: move HEVC stateless controls out of staging

2022-07-15T16:36:58+00:00

HEVC uAPI is used by 2 mainline drivers (Hantro, Cedrus)
and at least 2 out-of-tree drivers (rkvdec, RPi).
The uAPI has been reviewed so it is time to make it 'public' by
un-staging it.

media: v4l2-ctrls: add support for dynamically allocated arrays.

2022-07-15T15:20:53+00:00

Implement support for dynamically allocated arrays.

Most of the changes concern keeping track of the number of elements
of the array and the number of elements allocated for the array and
reallocating memory if needed.

media: uapi: move MPEG-2 stateless controls out of staging

2021-05-23T17:21:31+00:00

Until now, the MPEG-2 V4L2 API was not exported as a public API,
and only defined in a private media header (media/mpeg2-ctrls.h).

After reviewing the MPEG-2 specification in detail, and reworking
the controls so they match the MPEG-2 semantics properly,
we can consider it ready.
