v0.4 Release

Devicetree Specification v0.4-rc1

Devicetree Specification 0.3

* Added more recommended generic node names
* Document generic nexus binding
* codespell support and spelling fixes

Switch back to Rob's OAuth token

Really, we need to setup a GH 'machine user' so more than one person can
deploy releases.

Signed-off-by: Rob Herring <robh@kernel.org>

Fixed misspelling: of->or

Devicetree Specification 0.2

Mostly editorial changes from v0.1. Primary purpose for this release is to work
through the mechanics of cutting a release. Right now it is more labour
intensive than I would like for two reasons:

- The GitHub OAuth key must be manually changed to the person cutting the
  release. I would like it to be automatically selected based on who signed
  the release tag
- The pre-release flag needs to be manually changed between -pre/-rc and full
  releases. This also should be automatically determined based on tag pattern
  matching

Content changes include:
* Added more recommended generic node names
* Added interrupts-extended
* Additional phy times
* Filled out detail in source language chapter
* Editorial changes
* Added changebar version to release documents

v0.2-rc1

Travis-ci builds are working well, the changebar version seems to be
correct. Getting close to release state, so do the first (and hopefully
only) -rc.

Fourth (and hopefully last) prerelease of v0.2

Third prerelease for v0.2.

Minor editorial changes and a repository cleanups. Still need to get
changebar version of PDF building before release.

v0.2-pre2

Prerelease in preparation for the v0.2 release before end of December 2017
