When run 'ls' command, we can get the register address of the device. Take CTI for example, if we want to set the config for modem CTI, but we can't know which CTI is modem CTI from all current information. cti_sys0 -> ../../../devices/platform/soc@0/138f0000.cti/cti_sys0 cti_sys1 -> ../../../devices/platform/soc@0/13900000.cti/cti_sys1 Add label to show hardware context information of each coresight device. There will be a sysfs node label in each device folder. cat /sys/bus/coresight/devices/cti_sys0/label Signed-off-by: Mao Jinlong Reviewed-by: Krzysztof Kozlowski Reviewed-by: Mike Leach --- .../devicetree/bindings/arm/arm,coresight-cti.yaml | 6 ++++++ .../devicetree/bindings/arm/arm,coresight-dummy-sink.yaml | 6 ++++++ .../devicetree/bindings/arm/arm,coresight-dummy-source.yaml | 6 ++++++ .../bindings/arm/arm,coresight-dynamic-funnel.yaml | 6 ++++++ .../bindings/arm/arm,coresight-dynamic-replicator.yaml | 6 ++++++ .../bindings/arm/arm,coresight-static-funnel.yaml | 6 ++++++ .../bindings/arm/arm,coresight-static-replicator.yaml | 6 ++++++ .../devicetree/bindings/arm/arm,coresight-tmc.yaml | 6 ++++++ .../devicetree/bindings/arm/qcom,coresight-tpda.yaml | 6 ++++++ .../devicetree/bindings/arm/qcom,coresight-tpdm.yaml | 6 ++++++ 10 files changed, 60 insertions(+) diff --git a/Documentation/devicetree/bindings/arm/arm,coresight-cti.yaml b= /Documentation/devicetree/bindings/arm/arm,coresight-cti.yaml index 2d5545a2b49c..5ca6d3d313a3 100644 --- a/Documentation/devicetree/bindings/arm/arm,coresight-cti.yaml +++ b/Documentation/devicetree/bindings/arm/arm,coresight-cti.yaml @@ -98,6 +98,12 @@ properties: power-domains: maxItems: 1 =20 + label: + $ref: /schemas/types.yaml#/definitions/string + description: + Define the label which can describe what kind of HW or system the + coresight device belongs to. + arm,cti-ctm-id: $ref: /schemas/types.yaml#/definitions/uint32 description: diff --git a/Documentation/devicetree/bindings/arm/arm,coresight-dummy-sink= .yaml b/Documentation/devicetree/bindings/arm/arm,coresight-dummy-sink.yaml index 08b89b62c505..bc82cd1f3595 100644 --- a/Documentation/devicetree/bindings/arm/arm,coresight-dummy-sink.yaml +++ b/Documentation/devicetree/bindings/arm/arm,coresight-dummy-sink.yaml @@ -39,6 +39,12 @@ properties: enum: -
