Subject: [PATCH v3 3/7] clk: qcom: hfpll: register as clock provider
Date: Mon, 25 Nov 2019 14:59:05 +0100	[thread overview]
Message-ID: <20191125135910.679310-4-niklas.cassel@linaro.org> (raw)
In-Reply-To: <20191125135910.679310-1-niklas.cassel@linaro.org>

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@linaro.org>

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