Subject: [PATCH 6/6] clk: samsung: Introduce Exynos850 clock driver
Date:   Tue, 14 Sep 2021 18:56:07 +0300
Message-Id: <20210914155607.14122-7-semen.protsenko@linaro.org>
In-Reply-To: <20210914155607.14122-1-semen.protsenko@linaro.org>
References: <20210914155607.14122-1-semen.protsenko@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

This is the initial implementation adding only basic clocks like UART,
MMC, I2C and corresponding parent clocks. Design is influenced by
Exynos7 and Exynos5433 clock drivers.
