Subject: [PATCH v2 3/3] clk: qcom: mmcc-msm8994: Add MSM8992 support
Date:   Thu, 17 Jun 2021 21:27:25 +0200
Message-Id: <20210617192725.126743-3-konrad.dybcio@somainline.org>
In-Reply-To: <20210617192725.126743-1-konrad.dybcio@somainline.org>

Content-Transfer-Encoding: 8bit
Precedence: bulk

MSM8992 features less clocks & GDSCS and has different
freq tables for some of them.
