The Devicetree Specification has superseded the ePAPR as the base specification for bindings. Update files in Documentation to reference the new document. First reference to ePAPR in Documentation/devicetree/bindings/arm/cci.txt is generic, remove it. Some files are not updated because there is no hypervisor chapter in the Devicetree Specification: Documentation/devicetree/bindings/powerpc/fsl/msi-pic.txt Documenation/virtual/kvm/api.txt Documenation/virtual/kvm/ppc-pv.txt Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org>
