Why does this change add this question:
ARM Versatile (Express) reference platforms clock source (CLKSRC_VERSATILE) [N/y/?] (NEW) ?
This option enables clock source based on free running counter available in the "System Registers" block of ARM Versatile, RealView and Versatile Express reference platforms.
Symbol: CLKSRC_VERSATILE [=n] Type : boolean Prompt: ARM Versatile (Express) reference platforms clock source Location: -> Device Drivers -> Clock Source drivers Defined at drivers/clocksource/Kconfig:216 Depends on: GENERIC_SCHED_CLOCK [=y] && !ARCH_USES_GETTIMEOFFSET [=n] Selects: CLKSRC_OF [=n]
to a MIPS configuration? I find it silly, this appears a platform device to me (use reverse dependencies?).
