[PATCH v2] of: update ePAPR references to point to Devicetree Specification
frowand.list at gmail.com

Thu Jun 22 09:15:39 PDT 2017
From: Frank Rowand <frank.rowand at sony.com>
The Devicetree Specification has superseded the ePAPR as the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 at sony.com>

changes from v1:
- remove boilerplat ePAPR reference from cci.txt
