Subject: [PATCH 03/14] mfd: remove unused si476x driver
Date: Wed, 9 Sep 2026 15:21:40 +0200 [thread overview]
Message-ID: <20260909132153.1596191-4-arnd@kernel.org> (raw)
In-Reply-To: <20260909132153.1596191-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
The si476x driver was added in linux-3.9 without devicetree
support, and has always failed the probe function in the
absence of a si476x_platform_data definition.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

-The SI476x Driver
-=================
-
-Copyright |copy| 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
-
-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:
-
- .. tabularcolumns:: |p{7ex}|p{12ex}|L|
-
