Subject: [PATCH] arm64: dts: qcom: sdm845-mtp: Mark protected gcc clocks
Date: Mon, 5 Nov 2018 21:50:13 -0800 [thread overview]
Message-ID: <20181106055013.11271-1-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20181105194011.43770-1-swboyd@chromium.org>
As of v4.20-rc1 probing the GCC driver on a SDM845 device with the
standard security implementation causes an access violation and an
immediate system restart. Use the protected-clocks property to mark the
offending clocks protected for the MTP, in order to allow it to boot.
