Move it to remoteproc as it better suits the purpose - communication channel with remote processor. Signed-off-by: Krzysztof Kozlowski Acked-by: Rob Herring --- Changes since v1: 1. :: -> : 2. Correct qcom,intents type. There are no strict dependencies on other patches, but the previous "qcom,apcs-kpss-global" should end up in the same cycle (or earlier) as this one. --- .../remoteproc/qcom,glink-rpm-edge.yaml | 99 +++++++++++++++++++ .../bindings/soc/qcom/qcom,glink.txt | 94 ------------------ 2 files changed, 99 insertions(+), 94 deletions(-) create mode 100644 Documentation/devicetree/bindings/remoteproc/qcom,glink-rpm-edge.yaml delete mode 100644 Documentation/devicetree/bindings/soc/qcom/qcom,glink.txt diff --git a/Documentation/devicetree/bindings/remoteproc/qcom,glink-rpm-edge.yaml b/Documentation/devicetree/bindings/remoteproc/qcom,glink-rpm-edge.yaml new file mode 100644 index 000000000000..f5a044e20c4e --- /dev/null +++ b/Documentation/devicetree/bindings/remoteproc/qcom,glink-rpm-edge.yaml @@ -0,0 +1,99 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/remoteproc/qcom,glink-rpm-edge.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Qualcomm G-Link RPM edge + +description: | + Qualcomm G-Link edge, a FIFO based mechanism for communication with Resource + Power Manager (RPM) on various Qualcomm platforms. + +maintainers: + - Bjorn Andersson + +properties: + compatible: + const: qcom,glink-rpm + + label: + $ref: /schemas/types.yaml#/definitions/string + description: + Name of the edge, used for debugging and identification purposes.
