Adding high-level "if PPS" makes lower-level dependency tests superfluous. Link: http://lkml.kernel.org/r/alpine.LFD.2.20.1708261050500.8156@localhost.localdomain Signed-off-by: Robert P. J.

If you say yes here you get support for a PPS debugging client
|
|
which uses a kernel timer to generate the PPS signal.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called pps-ktimer.

help
|
|
If you say yes here you get support for a PPS source using
|
|
GPIO. To be useful you must also register a platform device
|
|
specifying the GPIO pin and other options, usually in your board
|
|
setup.
