bool "Use GIC global counter for clock events"
depends on IRQ_GIC && !(MIPS_SEAD3 || MIPS_MT_SMTC)
help
Use the GIC global counter for the clock events. The R4K clock
event driver is always present, so if the platform ends up not
detecting a GIC, it will fall back to the R4K timer for the
generation of clock events.
