Subject: [PATCH v5 1/7] clk: qcom: Add WCSS gcc clock control for QCS404
Date: Fri, 26 Jul 2019 14:53:26 +0530
Message-ID: <20190726092332.25202-2-govinds@codeaurora.org> (raw)
In-Reply-To: <20190726092332.25202-1-govinds@codeaurora.org>

Add support for the WCSS QDSP gcc clock control used on qcs404
based devices. This would allow wcss remoteproc driver to control
the required gcc clocks to bring the subsystem out of reset.
