ARM: shmobile: r8a73a4/r8a7790 CMT and Arch timer update
[PATCH 01/04] ARM: shmobile: Add r8a7790 CMT00 clock event [PATCH 02/04] ARM: shmobile: Make r8a7790 Arch timer optional [PATCH 03/04] ARM: shmobile: Add r8a73a4 CMT10 clock event [PATCH 04/04] ARM: shmobile: Make r8a73a4 Arch timer optional
Add clock event support through a CMT timer channel for the SoCs r8a7790 and r8a73a4 as well as APE6EVM and Lager boards.
Also, to be able to test the CMT timers, make it possible to deselect Arch timer and instead rely on predefined values for
udelay()and instead of local timer for SMP use broadcast.A nice side effect of this is that high resolution timers now become available. The reason for the is that the Arch timer sets the C3STOP flag which in turn will tell the time keeping code to not allow high resolution timer without an additional clock event. So here they are.
