Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee38
("docs: Create a user-space API guide").
As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.
Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

Complex signed 14-bit little endian IQ sample
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
This format contains sequence of complex number samples. Each complex
|
|
number consist two parts, called In-phase and Quadrature (IQ). Both I
|
|
and Q are represented as a 14 bit signed little endian number. I value
|
|
comes first and Q value after that. 14 bit value is stored in 16 bit
|
|
space with unused high bits padded with 0.
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
