Well, I have another opinion on this...
Let's see, yeah, we are using following method in EXYNOS4 DT...
- disabling IPs in SoC DT source and enabling IPs in board DT source
But as I said, in EXYNOS5440 DT, I want to use following, because most of
them should be enabled/used.
- enabling IPs in SoC DT source and no need enabling in board DT source.
I mean, it depends on each SoC's situation.
Thanks.
