ARM: ks8695: add board support for the SnapGear boards based on the KS8695 A number of boards produced by SnapGear are based on the Micrel KS8695 SoC. Add board support to the KS8695 kernel code to support them. The following machine type entries will need to be added back into the mach-types file with these in mainline: lite300 MACH_LITE300 LITE300 408 se4200 MACH_SE4200 SE4200 809 sg310 MACH_SG310 SG310 1564 Signed-off-by: Greg Ungerer <gerg@uclinux.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Olof Johansson <olof@lixom.net>

ARM: delete struct sys_timer Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single 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 Includes mach-omap2 fixes from Igor Grinberg.
