Subject: [PATCH 2/7] dt-bindings: clock: Add bindings for Exynos850 CMU_IS
Date:   Mon,  8 Aug 2022 21:15:59 +0300
Message-Id: <20220808181559.10438-1-semen.protsenko@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

CMU_IS generates CSIS, IPP, ITP, VRA and GDC clocks for BLK_IS. Add
clock indices and bindings documentation for CMU_IS domain.
