This patch series is written to clean up dependancy of ARCH_EXYNOS
Not all exynos device have IRQ_COMBINER, especially aarch64 EXYNOS
but it is built for all exynos devices.
Thus add the config for EXYNOS_IRQ_COMBINER
remove direct between ARCH_EXYNOS and exynos-combiner.c
and only selected on the aarch32 devices

Hi,
There is no changelog and versioning of this patch so I do not
understand how it differs with previous. It's a resend? v2? It brings
the confusion and looks like you're ignoring previous comments.
Looks the same and looks like breaking Exynos platforms in the same way.
If you not want to skip combiner on ARMv8, it makes sense, then please
follow the approach we did for Pinctrl drivers (PINCTRL_EXYNOS_ARM and
PINCTRL_EXYNOS_ARM64).
Best regards,
Krzysztof

Ah, now I see the second patch. Still you break bisect which requires
specific ordering of patches or squashing them into one. Optionally
this could be default=y if ARCH_EXYNOS && ARM. I prefer just squashing
both into one patch in this case.

Since you make it a separate option, make it COMPILE_TEST.

you mean squashing two files arch/arm/mach-exynos/Kconfig and
arch/arm/mach-exynos/Kconfig into one patch
or squashing into only one file like blow?
+config EXYNOS_IRQ_COMBINER
+ bool "Samsung Exynos IRQ combiner support"
+ depends on (ARCH_EXYNOS && ARM) || COMPILE_TEST
+ default y
I prefer first one (squashing two files into one patch)

Typo from my side. I wanted to say "No point" - this should not be
selectable by user.

Not entirely. The bool should be also with "if COMPILE TEST" so:
config EXYNOS_IRQ_COMBINER
bool "Samsung Exynos IRQ combiner support" if COMPILE_TEST
depends on (ARCH_EXYNOS && ARM) || COMPILE_TEST
