The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

tristate "PPS support"
|
|
---help---
|
|
PPS (Pulse Per Second) is a special pulse provided by some GPS
|
|
antennae. Userland can use it to get a high-precision time
|
|
reference.
|
|
|
|
Some antennae's PPS signals are connected with the CD (Carrier
|
|
Detect) pin of the serial line they use to communicate with the
|
|
host. In this case use the SERIAL_LINE client support.
|
|
|
|
Some antennae's PPS signals are connected with some special host
|
|
inputs so you have to enable the corresponding client support.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called pps_core.ko.

Say Y here if you want the PPS support to produce a bunch of debug
|
|
messages to the system log. Select this if you are having a
|
|
problem with PPS support and want to see more of what is going on.

help
|

This option adds support for direct in-kernel time
|
|
synchronization using an external PPS signal.
|
|
|
|
It doesn't work on tickless systems at the moment.
