Subject: [PATCH v3 3/3] clk: qcom: mmcc-msm8994: Add MSM8992 support
Date:   Fri, 18 Jun 2021 13:14:34 +0200
Message-Id: <20210618111435.595689-3-konrad.dybcio@somainline.org>
In-Reply-To: <20210618111435.595689-1-konrad.dybcio@somainline.org>

Precedence: bulk

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

Signed-off-by: Konrad Dybcio <konrad.dybcio@somainline.org>

Changes since v2:
- Use NULL instead of 0 for disabled clocks
