Merge branch 'omap1' of... 

Merge branch 'omap1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/boards

* 'omap1' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  input: serio: ams-delta: toggle keyboard power over GPIO
  omapfb: lcd_ams_delta: drive control lines over GPIO
  MTD: NAND: ams-delta: use GPIO instead of custom I/O
  LED: drop leds-ams-delta driver
  ARM: OMAP1: ams-delta: supersede custom led device by leds-gpio
  ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpio
  ARM: OMAP1: ams-delta: register latch dependent devices later
