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. * tag 'omap-for-v3.13/quirk-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (523 commits) ARM: configs: omap2plus_defconfig: enable dwc3 and dependencies ARM: OMAP2+: Add WLAN modules and of_serial to omap2plus_defconfig ARM: OMAP2+: Run make savedefconfig on omap2plus_defconfig to shrink it ARM: OMAP2+: Add minimal 8250 support for GPMC ARM: OMAP2+: Use pdata quirks for wl12xx for omap3 evm and zoom3 ARM: OMAP: Move DT wake-up event handling over to use pinctrl-single-omap ARM: OMAP2+: Add support for auxdata pinctrl: single: Add support for auxdata pinctrl: single: Add support for wake-up interrupts pinctrl: single: Prepare for supporting SoC specific features ARM: OMAP2+: igep0020: use display init from dss-common ARM: OMAP2+: pdata-quirks: add legacy display init for IGEPv2 board +Linux 3.12-rc4 Signed-off-by: Kevin Hilman <khilman@linaro.org>
