Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and qcom,smd-channels missing properties to make sure dtbs_check doesn't fail right off the bat. Correct the name of the parent node in the example from smd-edge to glink-edge. Also change the file extension referenced in bindings remoteproc/qcom,glink-edge.yaml from txt to yaml. Co-developed-by: Srinivas Kandagatla Signed-off-by: Srinivas Kandagatla Co-developed-by: David Heidelberg Signed-off-by: David Heidelberg Signed-off-by: Abel Vesa --- Changes since v7: * fixed file extension in glink-edge yaml, issue reported by Rob's bot, and changed the commit message to reflect that too. * removed from commit message the mentioning of qcom,non-secure-domain, as suggested by Krzysztof. * added the qcom,vmids in the yaml, which was there in the original txt file. * mentioned in the commit message that the parent node name in the example is changed from smd-edge to glink-edge, since this is a change made compared to the original txt file .../devicetree/bindings/misc/qcom,fastrpc.txt | 88 ------------- .../bindings/misc/qcom,fastrpc.yaml | 123 ++++++++++++++++++ .../bindings/remoteproc/qcom,glink-edge.yaml | 2 +- 3 files changed, 124 insertions(+), 89 deletions(-) delete mode 100644 Documentation/devicetree/bindings/misc/qcom,fastrpc.txt create mode 100644 Documentation/devicetree/bindings/misc/qcom,fastrpc.yaml diff --git a/Documentation/devicetree/bindings/misc/qcom,fastrpc.txt b/Documentation/devicetree/bindings/misc/qcom,fastrpc.txt deleted file mode 100644 index 5ec124b138a6..000000000000 --- a/Documentation/devicetree/bindings/misc/qcom,fastrpc.txt +++ /dev/null @@ -1,88 +0,0 @@ -Qualcomm Technologies, Inc.
