Building those list is a standard procedure described in section '8.2.4 Decoding process for reference picture lists construction' of the H264 specification. We already have 2 drivers needing the same logic (hantro and rkvdec) and I suspect we will soon have more. Let's provide generic helpers to create those lists.

Enables the V4L2 sub-device pad-level userspace API used to configure

video format, size and frame rate between hardware blocks.

This API is mostly used by camera interfaces in embedded platforms.

Say Y here to enable the old-style fixed-range minor assignments.

Only useful if you rely on the old behavior and use mknod instead of udev.
|
|
|
|
When in doubt, say N.
