(Pulse Per Second) signals.
This patchset adds PPS generators class in order to have a well-defined
interface for these devices.
Changelog:
V1 -> V2:
* new file Documentation/ABI/testing/sysfs-pps-gen added in MAINTAINERS
* date for the documentation ABI set to v6.13 which will be released on 2025-02
* removed documentation for non-existent sysfs "name" entry
* spelling and/or syntax errors fixed
RFC -> V1:
* char device reworked (get_device/set_device)
* dummy driver has been moved in a separate patch
* idr_ replaced with ida_* functions
* fixes in include/uapi/linux/pps_gen.h
* MAINTAINERS updated
* new ioctl PPS_GEN_USESYSTEMCLOCK added
* new ioctl PPS_GEN_FETCHEVENT added
* .compat_ioctl dropped
* WARN_ON() removed from pps_gen_cdev_release()
* not needed pr_*() calls removed or replaced with dev_*()
* more quite driver
