Dear Rob, Pankaj,

I would like to proceed with this patchset. I guess your comment here
was about to change the compatible from generic exynos-like to a model
specific. How about this:
- compatible : Should contain "samsung,exynos4210-srom".

Is this okay?

(the oldest chip mentioning SROM controller as separate block is Exynos4210)


Best regards,
Krzysztof
