Subject: [PATCH 07/13] clk: qcom: hfpll: register as clock provider
Date:   Mon, 17 Dec 2018 10:46:24 +0100
Message-Id: <1545039990-19984-8-git-send-email-jorge.ramirez-ortiz@linaro.org>
In-Reply-To: <1545039990-19984-1-git-send-email-jorge.ramirez-ortiz@linaro.org>
References: <1545039990-19984-1-git-send-email-jorge.ramirez-ortiz@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make the output of the high frequency pll a clock provider.
On the QCS404 this PLL controls cpu frequency scaling.
