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.
