Testing with the rmi_f54 driver on the Lenovo X1 Carbon 6th gen laptop showed that the data is in little endian format. Update the documentation accordingly. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

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.
