Merge tag 'omap-for-v3.13/board-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/boards
From Tony Lindgren: Platform data changes for omaps for the display subsystem and n900 secure mode changes. Note that the n900 secure mode changes will still be needed for device tree based booting also. * tag 'omap-for-v3.13/board-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (508 commits) ARM: OMAP2+: display: Create omap_vout device inside omap_display_init ARM: OMAP2+: display: Create omapvrfb and omapfb devices inside omap_display_init ARM: OMAP2+: display: Create omapdrm device inside omap_display_init ARM: OMAP2+: drm: Don't build device for DMM RX-51: Add support for OMAP3 ROM Random Number Generator ARM: OMAP3: RX-51: ARM errata 430973 workaround ARM: OMAP3: Add secure function omap_smc3() which calling instruction smc #1 +Linux 3.12-rc4 Signed-off-by: Kevin Hilman <khilman@linaro.org>
