pps: generators: Use ktime_get_real_ts64() instead of ktime_get_snapshot()
There is no reason to use the more complex ktime_get_snapshot() for retrieving CLOCK_REALTIME.
Just use ktime_get_real_ts6

Just use ktime_get_real_ts64(), which avoids the extra timespec64 conversion as a bonus.
No functional change intended.

pps: generators: replace copy of pps-gen info struct with const pointer
Some PPS generator drivers may need to retrieve a pointer to their internal data while executing the PPS generator enable() method.
During the driver registration the pps_gen_device pointer is returned from the framework, and for that reason, there is difficulty in getting generator driver data back in the enable function. We won't be able to use container_of macro as it results in static assert, and we might end up in using static pointer.
To solve the issue and to get back the generator driver data back, we should not copy the struct pps_gen_source_info within the struct pps_gen_device during the registration stage, but simply save the pointer of the driver one. In this manner, driver may get a pointer to their internal data as shown below:
struct pps_gen_foo_data_s { ... struct pps_gen_source_info gen_info; struct pps_gen_device *pps_gen; ... };
static int __init pps_gen_foo_init(void) { struct pps_gen_foo_data_s *foo; ... foo->pps_gen = pps_gen_register_source(&foo->gen_info); ... }
Then, in the enable() method, we can retrieve the pointer to the main struct by using the code below:
static int pps_gen_foo_enable(struct pps_gen_device *pps_gen, bool enable) { struct pps_gen_foo_data_s *foo = container_of(pps_gen->info, struct pps_gen_foo_data_s, gen_info); ... }
