    Subject[PATCH v2 2/8] dt-bindings: clock: samsung: add bindings for Exynos external clock
    Date
    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.
