clocksource: add common i8253 PIT clocksource This is based upon both arch/arm/mach-footbridge/isa-timer.c and arch/x86/kernel/i8253.c.

clocksource: add common mmio clocksource Add a generic mmio clocksource, covering both 32-bit and 16-bit register access sizes, for up or down counters. This can be used to easily create clocksources for simple counter-based implementations.

clocksource: apb: Share APB timer code with other platforms The APB timers are an IP block from Synopsys (DesignWare APB timers) and are also found in other systems including ARM SoC's. This patch adds functions for creating clock_event_devices and clocksources from APB timers but does not do the resource allocation. This is handled in a higher layer to allow the timers to be created from multiple methods such as platform_devices. Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H.
