[PATCH v3] arm64: dts: msm8916: Enable CoreSight STM component

by Leo Yan

From: Georgi Djakov <georgi.djakov(a)linaro.org> Add DT binding for CoreSight System Trace Macrocell (STM) on msm8916, which can benefit the CoreSight development on DB410c. Signed-off-by: Georgi Djakov <georgi.djakov(a)linaro.org> Signed-off-by: Leo Yan <leo.yan(a)linaro.org> --- Changes from v2: * Correct for author name. Changes from v1: * alphabetically and address ordering for DT node; pad addresses with zeroes (Stephan Gerhold). arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi | 1 + arch/arm64/boot/dts/qcom/msm8916.dtsi | 27 +++++++++++++++++++++++ 2 files changed, 28 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi b/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi index 3a9538e1ec97..2165b7415add 100644 --- a/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi +++ b/arch/arm64/boot/dts/qcom/apq8016-sbc.dtsi @@ -410,6 +410,7 @@ &wcd_codec { &funnel0 { status = "okay"; }; &funnel1 { status = "okay"; }; &replicator { status = "okay"; }; +&stm { status = "okay"; }; &tpiu { status = "okay"; }; &smd_rpm_regulators { diff --git a/arch/arm64/boot/dts/qcom/msm8916.dtsi b/arch/arm64/boot/dts/qcom/msm8916.dtsi index 402e891a84ab..f02b976480d5 100644 --- a/arch/arm64/boot/dts/qcom/msm8916.dtsi +++ b/arch/arm64/boot/dts/qcom/msm8916.dtsi @@ -489,6 +489,26 @@ snoc: interconnect@580000 { <&rpmcc RPM_SMD_SNOC_A_CLK>; }; + stm: stm@802000 { + compatible = "arm,coresight-stm", "arm,primecell"; + reg = <0x00802000 0x1000>, + <0x09280000 0x180000>; + reg-names = "stm-base", "stm-stimulus-base"; + + clocks = <&rpmcc RPM_QDSS_CLK>, <&rpmcc RPM_QDSS_A_CLK>; + clock-names = "apb_pclk", "atclk"; + + status = "disabled"; + + out-ports { + port { + stm_out: endpoint { + remote-endpoint = <&funnel0_in7>; + }; + }; + }; + }; + /* System CTIs */ /* CTI 0 - TMC connections */ cti0: cti@810000 { @@ -562,6 +582,13 @@ funnel0_in4: endpoint { remote-endpoint = <&funnel1_out>; }; }; + + port@7 { + reg = <7>; + funnel0_in7: endpoint { + remote-endpoint = <&stm_out>; + }; + }; }; out-ports { -- 2.25.1
