*	treewide: Convert new and leftover hrtimer_init() users	Thomas Gleixner	6 days	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	hrtimer_setup() takes the callback function pointer as argument and initializes the timer completely. Replace hrtimer_init() and the open coded initialization of hrtimer::function with the new setup mechanism. Coccinelle scripted cleanup.

*	pps: generators: Add PPS Generator TIO Driver	Subramanian Mohan	2025-02-21	1	-0/+272
	The Intel Timed IO PPS generator driver outputs a PPS signal using dedicated hardware that is more accurate than software actuated PPS. The Timed IO hardware generates output events using the ART timer. The ART timer period varies based on platform type, but is less than 100 nanoseconds for all current platforms. Timed IO output accuracy is within 1 ART period. PPS output is enabled by writing '1' the 'enable' sysfs attribute. The driver uses hrtimers to schedule a wake-up 10 ms before each event (edge) target time. At wakeup, the driver converts the target time in terms of CLOCK_REALTIME to ART trigger time and writes this to the Timed IO hardware. The Timed IO hardware generates an event precisely at the requested system time without software involvement.
