Signed-off-by: Krzysztof Kozlowski Reviewed-by: Rob Herring --- Changes since v2: 1. Use new name of file in samsung,sysmmu.yaml and MAINTAINERS. Changes since v1: 1. Indent example with four spaces (more readable), 2. Remove unneeded types, 3. Add missing address in example and fix the name. --- .../bindings/iommu/samsung,sysmmu.yaml | 2 +- .../devicetree/bindings/power/pd-samsung.txt | 45 ------------- .../devicetree/bindings/power/pd-samsung.yaml | 66 +++++++++++++++++++ MAINTAINERS | 2 +- 4 files changed, 68 insertions(+), 47 deletions(-) delete mode 100644 Documentation/devicetree/bindings/power/pd-samsung.txt create mode 100644 Documentation/devicetree/bindings/power/pd-samsung.yaml diff --git a/Documentation/devicetree/bindings/iommu/samsung,sysmmu.yaml b/Documentation/devicetree/bindings/iommu/samsung,sysmmu.yaml index ecde98da5b72..7cdd3aaa2ba4 100644 --- a/Documentation/devicetree/bindings/iommu/samsung,sysmmu.yaml +++ b/Documentation/devicetree/bindings/iommu/samsung,sysmmu.yaml @@ -69,7 +69,7 @@ properties: description: | Required if the System MMU is needed to gate its power.
