TODO for the driver
|
||||
------------------------------
|
||||
|
||||
- According to the SiLabs' datasheet it is possible to update the
|
||||
firmware of the radio chip in the run-time, thus bringing it to the
|
||||
most recent version. Unfortunately I couldn't find any mentioning of
|
||||
the said firmware update for the old chips that I tested the driver
|
||||
against, so for chips like that the driver only exposes the old
|
||||
functionality.
|
||||
|
||||
|
||||
Parameters exposed over debugfs
|
||||
-------------------------------
|
||||
SI476x allow user to get multiple characteristics that can be very
|
||||
useful for EoL testing/RF performance estimation, parameters that have
|
||||
very little to do with V4L2 subsystem. Such parameters are exposed via
|
||||
debugfs and can be accessed via regular file I/O operations.
|
||||
|
||||
The drivers exposes following files:
|
||||
|
||||
* /sys/kernel/debug/<device-name>/acf
|
||||
This file contains ACF(Automatically Controlled Features) status
|
||||
information. The contents of the file is binary data of the
|
||||
following layout:
