Subject: [PATCH v3 2/8] dt-bindings: clock: samsung: add bindings for Exynos external clock
Date: Wed, 25 Aug 2021 15:40:50 +0200	[thread overview]
Message-ID: <20210825134056.219884-3-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210825134056.219884-1-krzysztof.kozlowski@canonical.com>

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.
