[RFC/PATCH 00/11] arm: omap: counter32k rework

Hi,

the following patches de-obfuscate arch/arm/mach-omap2/timer.c
and start moving code to drivers/clocksource. So far only counter32k
has been moved over.

Note that we can't get rid of all the code (yet) because there are
still platforms relying to legacy boot and because of the strong
coupling with OMAP's hwmod layer.

This is, for now, an RFC and has be written on top of [1]. Boot tested
with AM335x and AM437x.

ps: if anybody has a good idea on how to get rid of
register_persistent_clock(), please let me know
