Merge branch 'for-3.6/cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup

From Stephen Warren <swarren@wwwdotorg.org>:

This branch contains various minor cleanups, such as binding and .dts
renames, DT content cleanup, SDHCI support-8bit property usage cleanup, and
removal of some unnecessary sleep code.

* 'for-3.6/cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: dt: tegra: rename board files to match SoC
  ASoC: tegra: simplify Kconfig dependencies
  ARM: dt: tegra: remove legacy support-8bit property
  mmc: tegra: use bus-width property instead of support-8bit
  ARM: tegra: Remove flow controller programming
  dt: name all Tegra binding docs consistently
  ARM: tegra20: Rename "emc" to "memory-controller"
  ARM: dt: tegra20: Rename "emc" to "memory-controller"
  ARM: tegra{20,30}: Rename "mc" to "memory-controller"
  ARM: dt: tegra{20,30}.dtsi: Rename "mc" to "memory-controller"
  amba: tegra-ahb: Remove empty *_remove()
