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.
