I tested with fake compatibles like: samsung,cmu-exynos5433-cmu-top samsung,exynos54xx-cmu-cpif Best regards, Krzysztof

Compatible is a string-array, therefore the "select" should look for anything containing Samsung SoC part. This allows to validate cases like: - "samsung,exynos5250-gsc", "samsung,exynos5-gsc" - "samsung,exynos5250-pmu", "syscon" - "tesla,fsd-mct", "samsung,exynos4210-mct" Since Tesla FSD builts on top of Exynos blocks, add an adidtional pattern for it.
