That would work, but is that consistent with other timers?

Looks like a number of them have depends on + COMPILE_TEST.

Some examples:

config ROCKCHIP_TIMER
bool "Rockchip timer driver" if COMPILE_TEST
depends on ARM || ARM64

config ARMADA_370_XP_TIMER
bool "Armada 370 and XP timer driver" if COMPILE_TEST
depends on ARM

config ORION_TIMER
bool "Orion timer driver" if COMPILE_TEST
depends on ARM

config ARM_GLOBAL_TIMER
bool "Support for the ARM global timer" if COMPILE_TEST
select TIMER_OF if OF
depends on ARM

config CLKSRC_EXYNOS_MCT
bool "Exynos multi core timer driver" if COMPILE_TEST
depends on ARM || ARM64
