[PATCH 2/4] dt-bindings: soc: samsung: exynos-sysreg: split from syscon

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Split Samsung Exynos SoC SYSREG bindings to own file to narrow the
bindings and do not allow other parts of syscon.yaml.  This allows
further customization of Samsung SoC bindings.
