Merge branch 'for-3.6/boards' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/boards
From Stephen Warren <swarren@wwwdotorg.org>
This branch contains changes to Tegra board files, and related Kconfig and
Makefile changes. Highlights include:
* Removal of Seaboard/Springbank board files; these boards can now only be
used with device tree.
* Use of small parts of some non-DT board files from the DT board files. This
enables all features that the non-DT board files have, when booting from DT.
This will allow almost complete removal of all non-DT board files in v3.7.
* Other miscellaneous changes.
This branch is based on Tegra's for-3.6/cleanup branch from a previous pull
request.
* 'for-3.6/boards' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
ARM: tegra: use of_default_bus_match_table
ARM: tegra: add device tree AUXDATA for APBDMA
ARM: tegra: paz00: enable WiFi rfkill when booting from device tree
ARM: tegra: harmony: init regulators, PCIe when booting from DT
ARM: tegra: trimslice: enable PCIe when booting from device tree
ARM: tegra: remove Seaboard board files
ARM: tegra: remove CONFIG_MACH_TEGRA_DT
ARM: tegra: make .dts compilation depend on Tegra2 support
