Merge tag 'tegra-for-3.8-single-zimage' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/multiplatform
From Stephen Warren:
ARM: tegra: single-zImage preparation work
Various cleanups and enhancements are made to core Tegra code towards the
aim of including Tegra in a multi-platform ARM kernel:
RTC, timer, and TWD are configured via device tree.
SPARSE_IRQ is enabled.
Tegra's debug_ll options are simplified, and the macros brought into
line with other multi-platform implementations, and moved to the new
common location.
Two headers still need to be eliminated in order to include Tegra in a
multi-platform kernel/ <mach/{clk,powergate}.h>. A new common API needs
to be invented to replace parts of clk.h. powergate.h might be replaced
by regulators; this needs more investigation.
This pull request is based on tegra-for-3.8-dt, followed by a merge of
arm-soc's devel/debug_ll_init branch.
