Before (Exynos3/4/5) there was only one block called actually SYSREG. For example on Exynos5433 we have SYSREG_DISP, SYSREG_CAM1 and so on. These are different so we should have dedicated compatibles. The same for Tesla - please provide dedicated compatibles per each block. I'll fix Exynos5433. Maybe someone can also fix Exynos850 and Autov9. Best regards, Krzysztof

Maybe someone can also fix Exynos850 and Autov9. To clarify - in case of Tesla, you do not need the fallbacks, so you just add few of: - tesla,fsd-xxx-sysreg within the enum. For Exynos850 and Autov9, just like for Exynso5433, we should keep it backwards compatible, so we need fallbacks. Best regards, Krzysztof
