Stephen Boyd 220069945b clocksource: arch_timer: Add support for memory mapped timers ... Add support for the memory mapped timers by filling in the read/write functions and adding some parsing code. Note that we only register one clocksource, preferring the cp15 based clocksource over the mmio one. To keep things simple we register one global clockevent. This covers the case of UP and SMP systems with only mmio hardware and systems where the memory mapped timers are used as the broadcast timer in low power modes. The DT binding allows for per-CPU memory mapped timers in case we want to support that in the future, but the code isn't added here. We also don't do much for hypervisor support, although it should be possible to support it by searching for at least two frames where one frame has the virtual capability and then updating KVM timers to support it.
