From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Andersson Subject: [PATCH] arm64: dts: qcom: qcs404-evb: Mark WCSS clocks protected Date: Tue, 13 Aug 2019 20:09:42 -0700 Message-ID: <20190814030942.2638-1-bjorn.andersson@linaro.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Andy Gross , Niklas Cassel Cc: Rob Herring , Mark Rutland , linux-arm-msm@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org List-Id: devicetree@vger.kernel.org '7d0c76bdf227 ("clk: qcom: Add WCSS gcc clock control for QCS404")' introduces two new clocks to gcc. These are not used before clk_disable_unused() and as such the clock framework tries to disable them. But on the EVB these registers are only accessible through TrustZone, so these clocks must be marked as "protected" to prevent the clock code from touching them. Numerical values are used as the constants are not yet available in a common tree.
