From: Frank Rowand <frank.rowand@xxxxxxxx> The Devicetree Specification has superseded the ePAPR as the base specification for bindings.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@xxxxxxxx> --- changes from v1: - remove boilerplat ePAPR reference from cci.txt Documentation/devicetree/bindings/arm/cci.txt | 15 ++++----------- Documentation/devicetree/bindings/arm/cpus.txt | 13 +++++++------ Documentation/devicetree/bindings/arm/idle-states.txt | 4 ++-- Documentation/devicetree/bindings/arm/l2c2x0.txt | 4 ++-- Documentation/devicetree/bindings/arm/topology.txt | 4 ++-- Documentation/devicetree/bindings/bus/simple-pm-bus.txt | 2 +- Documentation/devicetree/bindings/chosen.txt | 3 ++- Documentation/devicetree/bindings/common-properties.txt | 2 +- Documentation/devicetree/bindings/crypto/fsl-sec4.txt | 4 ++-- Documentation/devicetree/bindings/crypto/fsl-sec6.txt | 4 ++-- .../devicetree/bindings/interrupt-controller/open-pic.txt | 5 ++--- Documentation/devicetree/bindings/net/ethernet.txt | 9 ++++++--- Documentation/devicetree/bindings/powerpc/fsl/cpus.txt | 6 +++--- Documentation/devicetree/bindings/powerpc/fsl/l2cache.txt | 2 +- .../devicetree/bindings/powerpc/fsl/srio-rmu.txt | 4 ++-- Documentation/devicetree/bindings/powerpc/fsl/srio.txt | 3 ++- Documentation/devicetree/booting-without-of.txt | 2 +- Documentation/devicetree/usage-model.txt | 2 +- Documentation/xtensa/mmu.txt | 6 +++--- 19 files changed, 46 insertions(+), 48 deletions(-) diff --git a/Documentation/devicetree/bindings/arm/cci.txt b/Documentation/devicetree/bindings/arm/cci.txt index 0f2153e8fa7e..9600761f2d5b 100644 --- a/Documentation/devicetree/bindings/arm/cci.txt +++ b/Documentation/devicetree/bindings/arm/cci.txt @@ -11,13 +11,6 @@ clusters, through memory mapped interface, with a global control register space and multiple sets of interface control registers, one per slave interface. -Bindings for the CCI node follow the ePAPR standard, available from: - -www.power.org/documentation/epapr-version-1-1/ - -with the addition of the bindings described in this document which are -specific to ARM. - * CCI interconnect node Description: Describes a CCI cache coherent Interconnect component @@ -50,10 +43,10 @@ specific to ARM. as a tuple of cells, containing child address, parent address and the size of the region in the child address space. - Definition: A standard property.
