Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

I2C (pronounce: I-squared-C) is a slow serial bus protocol used in
|
|
many micro controller applications and developed by Philips. SMBus,
|
|
or System Management Bus is a subset of the I2C protocol. More
|
|
information is contained in the directory <file:Documentation/i2c/>,
|
|
especially in the file called "summary" there.
|
|
|
|
Both I2C and SMBus are supported here. You will need this for
|
|
hardware sensors support, and also for Video For Linux support.
|
|
|
|
If you want I2C support, you should say Y here and also to the
|
|
specific driver for your bus adapter(s) below.
|
|
|
|
This I2C support can also be built as a module. If so, the module
|
|
will be called i2c-core.

Say Y here if you want to enable ACPI I2C operation region support.

Operation Regions allow firmware (BIOS) code to access I2C slave devices,
|

such as smart batteries through an I2C host controller driver.

Say Y here if you intend to run lm-sensors 3.1.1 or older, or any

Say Y here to use i2c-* device files, usually found in the /dev

directory on your system. They make it possible to have user-space

programs use the I2C bus. Information on how to do this is
|
|
contained in the file <file:Documentation/i2c/dev-interface.rst>.

This support is also available as a module. If so, the module

handle multiplexed I2C bus topologies, by presenting each
|

multiplexed segment as a I2C adapter.

|

Some I2C bus drivers require so-called "I2C algorithm" modules
|
|
to work. These are basically software-only abstractions of generic
|
|
I2C interfaces. This option will autoselect them so that you don't
|
|
have to care.
|
|
|
|
Unselect this only if you need to enable additional helper
|
|
modules, for example for use with external I2C bus drivers.
|
|
|
|
In doubt, say Y.

specification. At the moment, two extensions are supported:
|

the SMBus Alert protocol and the SMBus Host Notify protocol.

This module may be useful to developers of SMBus client drivers,

If you do build this module, be sure to read the notes and warnings

in <file:Documentation/i2c/i2c-stub.rst>.

If you don't know what to do here, definitely say N.
