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
