+Subject: [PATCH 005/347] ARM: at91: Implement clocksource selection
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.246-rt110.tar.xz
+
+Allow selecting and unselecting the PIT clocksource driver so it doesn't
+have to be compile when unused.

++ It can also be used as a clock event device supporting oneshot mode.
