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()
