title: NXP System Timer Module (STM)
maintainers:
- Daniel Lezcano <daniel.lezcano@kernel.org>
description:
The System Timer Module supports commonly required system and application
software timing functions. STM includes a 32-bit count-up timer and four
32-bit compare channels with a separate interrupt source for each channel.
The timer is driven by the STM module clock divided by an 8-bit prescale
value.
