Subject: [PATCH v3 4/4] arm64: dts: sc7180: Add DSI and MDP OPP tables and power-domains
Date: Thu,  9 Jul 2020 16:34:34 +0530
Message-ID: <1594292674-15632-5-git-send-email-rnayak@codeaurora.org> (raw)
In-Reply-To: <1594292674-15632-1-git-send-email-rnayak@codeaurora.org>

Add the OPP tables for DSI and MDP based on the perf state/clk
requirements, and add the power-domains property to specify the
scalable power domain.
