| | | | | | | | | | | | | | | | Prefer KEY_NUMERIC_* for number buttons on remotes. Now all the remotes use KEY_NUMERIC_[0-9] for the number buttons rather than keys that could be affected by modifiers (Caps-Lock, or Num-Lock) or regional keymaps.

* media: Clarify the meaning of file descriptors in VIDIOC_DQBUFTomasz Figa2019-06-211-0/+8
| | | | | | | | | | | | | When the application calls VIDIOC_DQBUF with the DMABUF memory type, the v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf file descriptors. However, the current documentation does not explain whether those are new file descriptors referring to the same DMA-bufs or just the same integers as passed to VIDIOC_QBUF back in time. Clarify the documentation that it's the latter.

The list of FIELD values was outdated, so it was a bit confusing. The FIELD_NONE description said that 'The driver may also indicate this order when it cannot distinguish between V4L2_FIELD_TOP and V4L2_FIELD_BOTTOM'. This is false, NONE really means a full frame and userspace depends on that. So drop this line completely. There are no drivers that do this anyway. FIELD_TOP/BOTTOM/ALTERNATE indicate that the number of lines in the buffer are that of a field, not frame, so returning NONE here would cause huge problems.

Split it up: each control class reference gets its own rst file, and this file just describes the Extended Control API. Each control class reference is also moved up one level into the table of contents to make it easier to find e.g. the codec control reference. Finally I rearranged the order so that all camera-related control classes are grouped together, ditto for codec/jpeg and fm-rx/tx. The ext-ctrls-codec.rst is still pretty big and it is a candidate to split up further in the future, possibly per codec.

| | | | | | | | | | | | | | | | | | | | | | Allow to add fixed quantization parameter offset between luma and chroma quantization parameters. This control directly corresponds to the chroma_qp_index_offset field of the h.264 picture parameter set.

| | | | | | | | | | | | | | | | | | | | | | | | Allow to enable h.264 constrained intra prediction (macroblocks using intra prediction modes are not allowed to use residual data and decoded samples of neighboring macroblocks coded using inter prediction modes). This control directly corresponds to the constrained_intra_pred_flag field in the h.264 picture parameter set.
