Merge tag 'omap-for-v3.10/board-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/boards
From Tony Lindgren <tony@atomide.com>: Board related changes for v3.10 merge window. These are pretty much all non-critical fixes for platform device initialization that will be needed until we can drop the board-*.c files and move to DT based boot. * tag 'omap-for-v3.10/board-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: board-4430sdp: Provide regulator to pwm-backlight ARM: OMAP: zoom: Use pwm stack for lcd and keyboard backlight ARM: OMAP2+: omap2plus_defconfig: Add support for BMP085 pressure sensor omap2+: Remove useless Makefile line omap2+: Remove useless Makefile line ARM: OMAP: RX-51: add missing regulator supply definitions for lis3lv02d ARM: OMAP1: fix omap_udc registration Includes an update to Linux 3.9-rc6 Signed-off-by: Arnd Bergmann <arnd@arndb.de>
