These are not really compatible or your commit msg is incomplete. Don't use deprecated syntax and backwards compatible solutions for new hardware. Best regards, Krzysztof

Are you sure? The deprecated one is actually the item above. From what I
understand, those are generic sysregs and don't mention their functions.
- items:
- enum:
- samsung,exynos5433-sysreg
- samsung,exynos850-sysreg
- samsung,exynosautov9-sysreg
- const: syscon
deprecated: true

What I meant is, usually compatibles go like this (in order): "samsung,exynos<soc>-<function>-sysreg", "samsung,exynos<soc>-sysreg", "syscon" But the deprecated item had its compatibles like this: "samsung,exynos<soc>-sysreg", "syscon" That is what I meant by "generic". It doesn't mention <function>. And my additions adhere to the former. So does [1], [2], and [3]. None are deprecated.
