Linus Walleij	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.

Linus Walleij	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.

Linus Walleij	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.

Russell King	b7c11ec9f1	Merge branch 'u300' into devel ... Conflicts: arch/arm/Makefile Updates: arch/arm/mach-u300/core.c arch/arm/mach-u300/timer.c	2009-06-14 11:01:44 +01:00
Linus Walleij	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.
