3af8a8dad0 ARM: 6297/1: move U300 timer to dynamic clock lookup
This moves the U300 timer code to look up its clock rate from the
clock framework as is apropriate and also switches it over to use
the generic code for *calc_mult_shift() on clock source and clock
event.

b7276b236d ARM: 6296/1: clock U300 intcon and timer properly
This removes the quirks to clock the U300 VIC and timer by custom
hooks and moves the control out to the clock framework where it
belongs. This is possible now that clocks are available early.

a2ca00ea93 ARM: 5704/1: U300 sched_clock implementation v2
This adds the long debated sched_clock() override for the weak
in-kernel jiffybased sched_clock(). The implementation is more or
less identical to the one used in arch/arm/plat-omap/common.c
and at last attempt to merge this the merge was postponed at the
request of Peter Zijlstra due to pending discussions regarding
generalized clocksource-based sched_clock() implementations by
adding a flag to the clocksource. However that discussion ended
up with the generic code needing to be rewritten and Paul Mundt
see no reason not to proceed with this for the time being as it
can be easily converted once the generic code is in place.

bb3cee2b35 [ARM] 5473/1: U300 core machine support
This adds core support for the ST-Ericsson U300 series
platforms: U300, U330, U335 and U365. Supports memory
mappings, interrupt controller, system timer (clocksource
and clockevents), and binds to the existing drivers for
the PrimeCells used in this design: PL190 (VIC), PL180
(MMC/SD host) and PL011 (UART). This is intented to serve
as starting point for our mainling work, more patches to
follow.
