Subject: [PATCH 2/3] dt-bindings: clock: samsung: add bindings for Exynos external clock
Date: Mon, 9 Aug 2021 14:05:43 +0200 [thread overview]
Message-ID: <20210809120544.56596-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210809120544.56596-1-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.
