Merge tag 'omap-for-v3.13/quirk-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt
From Tony Lindgren:
Changes needed to prepare for making omap3 device tree only:
- Always build in board-generic, and add pdata quirks and auxdata
support for it so we have all the pdata related quirks
in the same place.
- Merge of the drivers/pinctrl changes that are needed for PM
to continue working on omap3 and also needed for other omaps
eventually. The three pinctrl related patches have been acked
by Linus Walleij and are pulled into both the pinctrl tree
and this branch.
- Few defconfig related changes for drivers needed.
