Currently a syscon entity can be only registered directly through a
platform device that binds to a dedicated syscon driver. However in
certain use cases it is desirable to make a device used with another
driver a syscon interface provider.
For example, certain SoCs (e.g. Exynos) contain system co

Hello Everyone,
This is yet another attempt to finally make Exynos SYSMMU driver fully
