2f926eecdf arm/tegra: pcie: fix return value of function
In previous patch (arm/tegra: add timeout to PCIe PLL lock detection loop)
tegra_pcie_enable_controller() function type has been changed from
void to int, but the last return statement wasn't converted, so
function returns undefined value. Fix it.

Also while at it, address couple of minor concerns raised by reviewers:
use usleep_range for delay, and lower the value of timeout to 300ms
to be consistent with Nvidia Vibrante kernel.

6f6f6a7029 ARM: create a common IOMEM definition
Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

795d5fd4b8 arm/tegra: add timeout to PCIe PLL lock detection loop
Tegra PCIe driver waits for PLL to lock using busy loop.
If PLL fails to lock for some reason, this leads to silent lockup
while booting (as PCIe code is not modular).

Fix by adding timeout, so if PLL doesn't lock in a couple
of seconds, just PCIe driver fails and machine continues to boot.

448b98047c arm/tegra: fix harmony pinmux for PCIe
Commit 6e96aca397 (arm/tegra: Harmony PCIe: Don't touch pinmux)
removed runtime tri-state toggling for PCIe related pinmux groups,
but it seems that the fact that all of them are tri-state by default
has been overlooked. Change defaults for these groups to TEGRA_TRI_NORMAL.

849ad9d819 Merge tag 'tegra-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/olof/tegra into tegra/cleanups
Minor fixes that weren't urgent enough to go into 3.3. The two paz00
patches are in mainline already but got merged after the branch point
for this branch, so they're duplicated. I also ended up merging in
rmk/for-armsoc into this later on to fix a bug introduced by it, so it's
included but it's not the base of this branch.

Tegra30: CPU A01=r2p7/>=A02=r2p9, NEON r2p3-50, PL310 r3p1-50

Based on work by Olof Johansson, although the actual list of errata is
somewhat different here, since I added a bunch more and removed one PL310
erratum that doesn't seem applicable.

Lots of relatively simple conflicts between the board
changes and stuff from the arm tree. This pulls in
the resolution from the samsung/cleanup tree, so we
don't get conflicting merges.

The common.c file gets changes from rmk/stable-devel (part of
next/cleanup), rmk/restart, samsung/dt and follow-on branches
from the samsung tree.

Pulling it all together here hopefully avoids having to do
even more conflicting merge changesets in this one file. What
a mess!

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
resource fixups.  This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

f88b8979d2 ARM: restart: remove the now empty arch_reset()
Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite.  Remove arm_machine_restart() as this function
no longer does anything useful.

For samsung platforms, remove the include of mach/system-reset.h and
plat/system-reset.h from their respective mach/system.h headers as these
just define their arch_reset functions.  As a result, the s3c2410 and
plat-samsung system-reset.h files are no longer referenced, so remove
these files entirely.
