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.

16-bit signed little endian Touch Delta
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
This format represents delta data from a touch controller.
|
|
|
|
Delta values may range from -32768 to 32767. Typically the values will vary
|
|
through a small range depending on whether the sensor is touched or not. The
|
|
full value may be seen if one of the touchscreen nodes has a fault or the line
|
|
is not connected.
|
|
|
|
**Byte Order.**
|
|
Each cell is one byte.
