Subject: ARM: debug: arrange Kconfig options more logically

Arrange the Kconfig options in rough alphabetical order, and place the
default 'none' and 'icedcc' options at the end.  This prefers the
platform specific debug option rather than the 'none' option, which is
what we actually want.

Subject: ARM: OMAP1: Fix pm_idle during suspend

Commit 9ccdac3662dbf3c75e8f8851a214bdf7d365a4bd ([ARM] idle:
clean up pm_idle calling, obey hlt_counter) removed a check
for NULL pm_idle.

Replace the NULL assignment in the OMAP1 code with disable_hlt()
to be in sync with the core code and restore the intended behavior.

Subject: ARM: clean up idle handlers

Let's factor out the need_resched() check instead of having it duplicated
in every pm_idle implementations to avoid inconsistencies (omap2_pm_idle
is missing it already).

The forceful re-enablement of IRQs after pm_idle has returned can go.
The warning certainly doesn't trigger for existing users.

To get rid of the pm_idle calling convention oddity, let's introduce
arm_pm_idle() allowing for the local_irq_enable() to be factored out
from SOC specific implementations. The default pm_idle function becomes
a wrapper for arm_pm_idle and it takes care of enabling IRQs closer to
where they are initially disabled.

And finally move the comment explaining the reason for that turning off
of IRQs to a more proper location.

From: Will Deacon <will.deacon@arm.com>
Date: Wed, 25 Jan 2012 11:36:33 +0100
Subject: ARM: 7300/1: realview: fix definition of GPIO0 interrupt on PB1176 to
 match TRM

Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an
AMBA device is registered with this parameter. With the pending NO_IRQ
cleanup, this will lead to a warning at boot time, since -1 is obviously
broken.

This patch updates the interrupt used for GPIO0 to match that specified
by the TRM. Unfortunately, it's not clear how to trigger this interrupt
so we trust that the documentation is correct.

Subject: ARM: amba: add amba_device allocation/add/put functions

Add functions to allocate and initialize AMBA device structures, and
add them to the Linux device manager.  This allows us to kill this
type of operation from individual platforms, moving it to core code.

Subject: ARM: tegra: select required CPU and L2 errata options

The ARM IP revisions in Tegra are:
Tegra20: CPU r1p1, PL310 r2p0
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.

Subject: 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.

Subject: 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.

Subject: 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.
