…/scm/linux/kernel/git/tmlind/linux-omap into next/boards From Tony Lindgren <tony@atomide.com>: Board updates for omaps mostly to deal with enabling display support with device tree until the bindings are ready. * tag 'omap-for-v3.8/board-v2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP1: use BUG_ON where possible OMAP: board-generic: enable DSS for panda & sdp boards OMAP: omap4sdp: move display init from board file to dss-common.c OMAP: panda: move display init from board file to dss-common.c ARM: OMAP2+: Nokia N9/N900/N950 -- mention product names Signed-off-by: Arnd Bergmann <arnd@arndb.de>
