Just a > thought. Removal of samsung_clk_of_register_fixed_ext() would cause ABI break, probably acceptable for these devices. Yet still, someone would have to do it and test it.

Document the bindings for Samsung Exynos external to SoC (oscclk/XXTI/XusbXTI) clock provided on boards. The bindings are already implemented in most of the Exynos clock drivers and DTS files.
