Good question! You'll need a driver under drivers/timer/ and for example
in U-Boot drivers/timer/omap-timer.c matches (based on compatibles) with
drivers/clocksource/timer-ti-dm-systimer.c and
drivers/clocksource/timer-ti-dm.c in the Linux kernel. Otherwise, a git
log drivers/timer/ shows various conversions of previous in-tree timers
to this framework.
