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
