OMAP TWL updates from Peter Ujfalusi <peter.ujfalusi@ti.com>:

Update for audio support via omap-twl4030 and pwm updates in board level,
and zoom-peripherals update to not request the TWL GPIO7.

* tag 'omap-for-v3.9/twl-signed-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP2+: Fix twl section warnings related to omap_twl4030_audio_init
  ARM: board-zoom: Do not request LCD panel enable GPIO from twl4030
  ARM: OMAP: omap3beagle: Use the pwm_leds driver to control the PMU_STAT led
  ARM: OMAP: board-4430sdp: Proper support for TWL6030 PWM LED/Backlight
  ARM: OMAP: sdp3430: Audio support via the common omap-twl4030 machine driver
  ARM: OMAP: zoom: Audio support via the common omap-twl4030 machine driver
  ARM: OMAP2+: twl-common: Allow boards to customize the twl4030 audio setup
  ARM: OMAP2+: twl-common: Add default twl4030 audio configuration
  ARM: OMAP: zoom: Zoom2 does not have extmute functionality
  ARM: OMAP: 3430sdp: Enable extmute functionality for audio
