Subject: [PATCH 2/2] clk: qcom: mmcc-8960: Add DSI related clocks
Date: Wed, 14 Oct 2015 18:24:45 +0530 [thread overview]
Message-ID: <1444827285-25233-3-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1444827285-25233-1-git-send-email-architt@codeaurora.org>
Add rcg and branch clk structs for DSI1 and DSI2 blocks found in MSM8960
and APQ8064. Each DSI instance has 4 pairs of rcg and branch clocks.
Populate arrays mmcc_msm8960_clks and mmcc_apq8064_clks with these clocks.
