SI476x Driver Readme

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:
