Subject: [PATCH 0/8] clocksource: Generalize Faraday timer

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!
