Note that, after discussion on v2, we decided to keep the existing meaning of label so as not to require changes to existing userspace software when moving to use binman nodes to specify the firmware layout. Signed-off-by: Simon Glass --- Changes in v5: - Add mention of why 'binman' is the vendor - Drop 'select: false' - Tidy up the compatible setings - Use 'tfa-bl31' instead of 'atf-bl31' Changes in v4: - Correct selection of multiple compatible strings Changes in v3: - Drop fixed-partitions from the example - Use compatible instead of label Changes in v2: - Use plain partition@xxx for the node name .../mtd/partitions/binman-partition.yaml | 50 +++++++++++++++++++ 1 file changed, 50 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/partitions/binman-partition.yaml diff --git a/Documentation/devicetree/bindings/mtd/partitions/binman-partition.yaml b/Documentation/devicetree/bindings/mtd/partitions/binman-partition.yaml new file mode 100644 index 00000000000000..37a413464b0ce5 --- /dev/null +++ b/Documentation/devicetree/bindings/mtd/partitions/binman-partition.yaml @@ -0,0 +1,50 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +# Copyright 2023 Google LLC + +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/mtd/partitions/binman-partition.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Binman partition + +maintainers: + - Simon Glass + +description: | + This corresponds to a binman 'entry'.
