Subject: [PATCH 0/2] m68k: Add DMA timers support for M5441x

This patch series adds support for DMA timers for the M5441x coldfire
family. The aim is to provide finer scheduler resolution and support for
high-resolution timers.

The first patch fixes the clocks and a typo. The second one is the
timers support addition. As there is no device tree, I did not use
TIMER_OF_DECLARE().
