Just recently I added support of ARM global timer as clocksource for Vybrid SoC. This SoC doesn't use cpufreq, hence it is safe to use the ARM global timer. The nice thing of device tree is, the patch to add support for that did not change a single line of code: http://thread.gmane.org/gmane.linux.kernel/1794460Hello Stefan, Your changes are not yet accepted in mainline, are they? (I don't see them in 3.18.5)
The changes have been accepted and went upstream in the 3.19 merge window, see https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=81c4831907fb00efdc97093b09e333009a57d005
Do you also use the ARM local timers in your port? Is there generic code to handle them?
It seems that there has been support for local timers once, but has been removed. But I'm not aware of the details: https://lkml.org/lkml/2013/2/22/49 -- Stefan
