Merge tag 'omap-for-v3.13/board-removal-signed-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt

From Tony Lindgren:
Changes needed to drop legacy booting support for some
omap3 boards.

Note that that these are based on a merge of the
following for the dependencies:

- v3.12-rc5 for fixes to pinctrl mask
- omap-for-v3.13/dt-signed to avoid pointless merge conflicts
- omap-for-v3.13/quirk-signed for legacy pdata handling

* tag 'omap-for-v3.13/board-removal-signed-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (125 commits)
  ARM: OMAP2+: remove legacy support for IGEP boards
  ARM: OMAP2+: Remove legacy support for zoom platforms
  ARM: OMAP2+: Remove legacy booting support for omap3 EVM
