[PATCH v5 0/3] powerpc: Open PIC binding and "pic-no-reset"

[Meador Inge]

This patch set provides a binding for Open PIC and implements support for
a new property, specified by that binding, called "pic-no-reset".

v5 - Moved the Open PIC binding to its rightful home of
     ".../Documentation/devicetree/bindings/".  Also, fixed up
     the lazy reset code to take better advantage of existing
     functions.  Finally, did some minor refactoring to put
     cpu id fetching in its own helper function.

v4 - Per Ben's feedback the protected sources implementation was left
     completely intact.  As such, the DTS cleanup and "protected-sources"
     removal patches were dropped.

v3 - the Open PIC binding was changed to be more consistent with existing
     bindings, several DTS files were cleaned up, "no-reset" was changed to
     "pic-no-reset", and a check to treat "protected-sources" as a synonym for
     "pic-no-reset" was added.
