From: "Ivan T. Ivanov" <ivan.ivanov@xxxxxxxxxx> Add initial set of CoreSight components found on Qualcomm's 8x16 chipset. Signed-off-by: Ivan T. Ivanov <ivan.ivanov@xxxxxxxxxx> Signed-off-by: Georgi Djakov <georgi.djakov@xxxxxxxxxx> --- This patch was on hold for some time, as it has a dependency on RPM clocks, which is now merged into clk-next. Changes since v3: (https://lkml.org/lkml/2015/5/11/134) * Include msm8916-coresight.dtsi into msm8916.dtsi Changes since v2: (https://lkml.org/lkml/2015/4/29/242) * Added "1x" to "qcom,coresight-replicator" compatible string, to match what devicetree bindings documentations says. arch/arm64/boot/dts/qcom/msm8916-coresight.dtsi | 254 ++++++++++++++++++++++++ arch/arm64/boot/dts/qcom/msm8916.dtsi | 2 + 2 files changed, 256 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/msm8916-coresight.dtsi diff --git a/arch/arm64/boot/dts/qcom/msm8916-coresight.dtsi b/arch/arm64/boot/dts/qcom/msm8916-coresight.dtsi new file mode 100644 index 000000000000..900f1f484a0a --- /dev/null +++ b/arch/arm64/boot/dts/qcom/msm8916-coresight.dtsi @@ -0,0 +1,254 @@ +/* + * Copyright (c) 2013 - 2015, The Linux Foundation.
