[PATCH 0/9] m68knommu: use ColdFire DMA timer

[PATCH 0/9] m68knommu: use ColdFire DMA timer

[gerg]

From: Greg Ungerer <gerg@uclinux.org>

Most of the modern ColdFire family members contain the DMA timer hardware
module. Build the support code for it and use it on those that do. We can
use it as an accurate time source.

I don't have test platforms based on all of these ColdFire types, it would
be really helpful if anyone that has any of these can test these changes.
It build tests fine on all these types, and it works on 520x and 527x
based platforms.

These changes are (neccessarily) on top of my recent patch series titled
"clean up timer code on the ColdFire 53xx".

[PATCH 8/9] m68knommu: enable clock when using dma_timer hardware module

[gerg]

From: Greg Ungerer <gerg@uclinux.org>

Acquire the SoC clock when using the DMA timer hardware module. With the
clock acquired we can enable it and get it ticking. On most ColdFire SoC
hardware the DMA timer clock is not enabled by default.
