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 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.

ARM: plat-nomadik: move MTU, kill plat-nomadik This moves the MTU timer driver from arch/arm/plat-nomadik to drivers/clocksource and moves the header file to the platform_data directory. As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.

ARM: ux500: delete U5500 support This platform has been obsoleted and was only available inside of ST-Ericsson, no users of this code are left in the world. This deletes the core U5500 support entirely in the same manner as the obsoleted U8500 silicon was previously deleted. The cpu_is_u5500() macros that can read out the CPU ID is left until the next kernel cycle, this makes it possible to merge deletion of dependent drivers without breakage. This also has the upside of removing the mailbox driver which was our only driver that was outside the drivers/* hiearchy, now the machine directory only handles machines and nothing else.

It uses the physical counter as the clock source and the virtual counter as sched_clock. The timer frequency can be specified via DT or read from the CNTFRQ_EL0 register. The physical counter is also accessible from user space allowing fast gettimeofday() implementation.
