It turns out that the Moxa is using a Faraday IP timer named FTTMR010. This is also what Aspeed's derivative is based on.
This series attempts to merge these two drivers into one to get lesser code to maintain. Also it incidentally adds a sched_clock() implementation to the Moxa and Aspeed, which is nice.
The patches can also be grabbed from here: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik.git/commit/?h=fttmr010
Future ideas include supporting the optional EXTCLK (32kHz clock) and delay timers. This will then get available on all three supported platforms = big win.
The patches can be applied as soon as Jonas Jensen and Joel Stanley says they work for them.
I have chosen to work on this body of code (rather than the Moxart code) as it is derived from code originally posted by Faraday themselves here: https://lwn.net/Articles/447919/
I hope we can get this to work!
