[PATCH v3 05/19] arm: exynos: pm_domains: add support for devices registered before arch_initcall

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

 



SYSMMU devices will be registered early before any other devices and
before calling arch_initcall. To add them to respective power domains,
additional scan of all platform devices is needed.
