I think this should be Samsung series of SoCs intead of Exynos series.
As such the file name could be samsung-fimd.txt.

"value should be one of the following:"

blank line here would make it more readable?

Please rephrase the above as there seems to be difference in order in
the above 2 lines itself. :)
