Merge branch 'omap/boards' into late/cleanup
* omap/boards:
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
