From: Stephen Warren
The overall aim of this series is to allow ARM (or indeed any) timer
drivers to be moved into drivers/clocksource without requiring a
struct or function prototype for each individual driver in include/linux.
The intent is eventually to create a single e.g. of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html
This requires some rework prior to implementing of_clocksource_init():
ARM uses struct sys_timer to represent the individual machine's timer
driver. Many of the patches in this series are ARM-specific changes to
get rid of this struct, leaving just a single init function instead.
One function pointer in the struct provides the implementation of
arch_gettimeoffset(). Removing the struct and moving drivers into the
generic drivers/clocksource directory requires an arch-agnostic way of
registering the implementation of this function. The first few patches
in the series provide that, and rework various architectures to make use
of this facility rather than implementing the same thing themselves.
It would probably be easiest to merge this whole series through the
arm-soc tree. Anything else would require some co-ordination.
