In commit fa6d79d (ARM: OMAP: Add initialisation for the real-time counter), the function realtime_counter_init() was added. However, if the kernel configuration option CONFIG_SOC_OMAP5 is not selected then the following compiler warning is observed. CC arch/arm/mach-omap2/timer.o arch/arm/mach-omap2/timer.c:489:20: warning: ‘realtime_counter_init’ defined but not used [-Wunused-function] Commit fa6d79d also introduced the kernel configuration option CONFIG_SOC_HAS_REALTIME_COUNTER. If this option is not selected then the a stub function for realtime_counter_init() is defined. For non-OMAP5 devices, there is no realtime counter and so realtime_counter_init() function and stub function are not used for these devices. Therefore, fix this warning by only allowing the kernel configuration option CONFIG_SOC_HAS_REALTIME_COUNTER to be enabled for OMAP5 devices.
