Subject: [PATCH v1 3/3] clk: qcom: Add display clock controller driver for SC7180
Date: Fri, 15 Nov 2019 15:34:05 +0530	[thread overview]
Message-ID: <1573812245-23827-4-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1573812245-23827-1-git-send-email-tdas@codeaurora.org>

Add support for the display clock controller found on SC7180
based devices. This would allow display drivers to probe and
control their clocks.
