Merge tag 'tegra-for-3.10-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup

From Stephen Warren <swarren@wwwdotorg.org>:

ARM: tegra: cleanup

This branch includes various cleanup of the core Tegra support.

* Unification of the separate board-dt-tegra*.c files into a single
  tegra.c, now that everything is DT-driven and basically identical.
* Use of_clk_get() in the Tegra clocksource driver so that clocks are
  described in DT rather than hard-coding clock names.
* Some cleanup of the PMC-related code, with the aim that the PMC
  "driver" contains more of the code that touches PMC registers, rather
  than spreading PMC register accesses through other files.
* Conversion of the "PMC" driver to acquire resources describe in device
  tree rather than hard-coding them.
* Use of common code for the CPU sleep TLB invalidation.

This branch is based on the previous fixes pull request.

* tag 'tegra-for-3.10-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra
