Kconfig: rename HAS_IOPORT to HAS_IOPORT_MAP
If the renamed symbol is defined lib/iomap.c implements ioport_map and ioport_unmap and currently (nearly) all platforms define the port accessor functions outb/inb and friend unconditionally. So HAS_IOPORT_MAP is the better name for this. Consequently NO_IOPORT is renamed to NO_IOPORT_MAP. The motivation for this change is to reintroduce a symbol HAS_IOPORT that signals if outb/int et al are available. I will address that at least one merge window later though to keep surprises to a minimum and catch new introductions of (HAS|NO)_IOPORT. The changes in this commit were done using: $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

ARM: 8009/1: dcscb.c: remove call to outer_flush_all()
Strictly speaking this call is a no-op on the platform where dcscb.c is used since it only has architected caches. The call was there as a hint to people inspired by this code when writing their own backend, but the hint might not always be correct. For example, if a PL310 were to be used it wouldn't be safe to call the regular outer_flush_all() as atomic instructions for locking are involved in that case and those instructions cannot be assumed to still be operational after v7_exit_coherency_flush() has returned. Given no other CPUs (in the cluster) should be running at that point then standard concurrency concerns wouldn't apply. So let's simply kill this call for now and enhance the existing comment.

ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used. (Uwe Kleine-König)
* The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new
hardware support without regressions. (Kumar Gala)
* A rework of some of the Kconfig logic to simplify multiplatform
support (Rob Herring)
* Samsung Exynos gets closer to supporting multiplatform (Sachin
Kamat and others)
* mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
* at91 gains some common clock framework support (Alexandre Belloni,
Jean-Jacques Hiblot and other French people).

ARM: 7962/2: Make all mcpm functions notrace
The functions in mcpm_entry.c are mostly intended for use during scary cache and coherency disabling sequences, or do other things which confuse trace ... like powering a CPU down and not returning. Similarly for the backend code. For simplicity, this patch just makes whole files notrace. There should be more than enough traceable points on the paths to these functions, but we can be more fine-grained later if there is a need for it. Jon Medhurst: Also added spc.o to the list of files as it contains functions used by MCPM code which have comments comments like: "might be used in code paths where normal cacheable locks are not working" Signed-off-by: Dave Martin <dave.martin@linaro.org> Signed-off-by: Jon Medhurst <tixy@linaro.org> Acked-by: Nicolas Pitre <nico@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |

ARM: vexpress/TC2: Implement MCPM power_down_finish()
This patch implements the power_down_finish() method for TC2, to
enable the kernel to confirm when CPUs are safely powered down.
The information required for determining when a CPU is parked
cannot be obtained from any single place, so a few sources of
information must be combined:
* mcpm_cpu_power_down() must be pending for the CPU, so that we
don't get confused by false STANDBYWFI positives arising from
CPUidle. This is detected by waiting for the tc2_pm use count
for the target CPU to reach 0.
* Either the SPC must report that the CPU has asserted
STANDBYWFI, or the TC2 tile's reset control logic must be
holding the CPU in reset.
Just checking for STANDBYWFI is not sufficient, because this
signal is not latched when the the cluster is clamped off and
powered down: the relevant status bits just drop to zero. This
means that STANDBYWFI status cannot be used for reliable
detection of the last CPU in a cluster reaching WFI.
This patch is required in order for kexec to work with MCPM on TC2.

Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"Included in this series are:
1. BE8 (modern big endian) changes for ARM from Ben Dooks
2. big.Little support from Nicolas Pitre and Dave Martin
3. support for LPAE systems with all system memory above 4GB
4. Perf updates from Will Deacon
5. Additional prefetching and other performance improvements from Will.
6. Neon-optimised AES implementation fro Ard.
7. A number of smaller fixes scattered around the place.
There is a rather horrid merge conflict in tools/perf - I was never
notified of the conflict because it originally occurred between Will's
tree and other stuff. Consequently I have a resolution which Will
forwarded me, which I'll forward on immediately after sending this
mail.
The other notable thing is I'm expecting some build breakage in the
crypto stuff on ARM only with Ard's AES patches. These were merged
into a stable git branch which others had already pulled, so there's
little I can do about this. The problem is caused because these
patches have a dependency on some code in the crypto git tree - I
tried requesting a branch I can pull to resolve these, and all I got
each time from the crypto people was "we'll revert our patches then"
which would only make things worse since I still don't have the
dependent patches. I've no idea what's going on there or how to
resolve that, and since I can't split these patches from the rest of
this pull request, I'm rather stuck with pushing this as-is or
reverting Ard's patches.
Since it should "come out in the wash" I've left them in - the only
build problems they seem to cause at the moment are with randconfigs,
and since it's a new feature anyway. However, if by -rc1 the
dependencies aren't in, I think it'd be best to revert Ard's patches"
I resolved the perf conflict roughly as per the patch sent by Russell,
but there may be some differences. Any errors are likely mine. Let's
see how the crypto issues work out..

ARM: vexpress/TC2: add support for CPU DVFS
SPC(Serial Power Controller) on TC2 also controls the CPU performance operating points which is essential to provide CPU DVFS. The M3 microcontroller provides two sets of eight performance values, one set for each cluster (CA15 or CA7). Each of this value contains the frequency(kHz) and voltage(mV) at that performance level. It expects these performance level to be passed through the SPC PERF_LVL registers. This patch adds support to populate these performance levels from M3, build the mapping to CPU OPPs at the boot and then use it to get and set the CPU performance level runtime.

ARM: vexpress: tc2: fix hotplug/idle/kexec race on cluster power down
On the TC2 testchip, when all CPUs in a cluster enter standbywfi and commit a power down request, the power controller will wait for standbywfil2 coming from L2 cache controller to shut the cluster down. By the time all CPUs in a cluster commit a power down request and enter wfi, the power controller cannot backtrack, or put it another way, a CPU must not be allowed to complete execution independently of the power controller, the only way for it to resume properly must be upon wake-up IRQ pending and subsequent reset triggered from the power controller. Current MCPM back-end for TC2 disables the GIC CPU IF only when power down is committed through the tc2_pm_suspend() method, that makes sense since a suspended CPU is still online and can receive interrupts whereas a hotplugged CPU, since it is offline, migrated all IRQs and shutdown the per-CPU peripherals, hence their PPIs. The flaw with this reasoning is the following. If all CPUs in a clusters are entering a power down state either through CPU idle or CPU hotplug, when the last man successfully completes the MCPM power down sequence (and executes wfi), power controller waits for L2 wfi signal to quiesce the cluster and shut it down. If, when all CPUs are sitting in wfi, an online CPU hotplugs back in one of the CPUs in the cluster being shutdown, that CPU receives an IPI that causes wfi to complete (since tc2_pm_down() method does not disable the GIC CPU IF in that case - CPU being hotplugged out, not idle) and the power controller will never see the stanbywfil2 signal coming from L2 that is required for shutdown to happen and the system deadlocks. Further to this issue, kexec hotplugs secondary CPUs out during kernel reload/restart. Because kexec may (deliberately) trash the old kernel text, it is not OK for CPUs to follow the MCPM soft reboot path, since instructions after the WFI may have been replaced by kexec. If tc2_pm_down() does not disable the GIC cpu interface, there is a race between CPU powerdown in the old kernel and the IPI from the new kernel that triggers secondary boot, particularly if the powerdown is slow (due to L2 cache cleaning for example). If the new kernel wins the race, the affected CPU(s) will not really be reset and may execute garbage after the WFI. The only solution to this problem consists in disabling the GIC CPU IF on a CPU committed to power down regardless of the power down entry method (CPU hotplug or CPU idle). This way, CPU wake-up is under power controller control, which prevents unexpected wfi exit caused by a pending IRQ. This patch moves the GIC CPU IF disable call in the TC2 MCPM implementation from the tc2_pm_suspend() method to the tc2_pm_down() method to fix the mentioned race condition(s).

ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

ARM: vexpress: tc2: disable GIC CPU IF in tc2_pm_suspend
To prevent cores from exiting wfi when they are about to be shut down the GIC CPU IF must be disabled so that the GIC CPU IF IRQ output line is not asserted to the cores. wfi completion must be prevented since, in absence of coordinating HW logic, if the power controller receives a standbywfi signal but in the meantime the processor restarts executing owing to a pending IRQ, the core might be reset when running in a non-quiescent state (eg with pending load/store transactions) Raw GIC distributor IRQ signals are routed to the power controller, that is capable of taking core out of reset on pending IRQs even if their GIC CPU IF is disabled, thus keeping the normal wfi behaviour. GIC CPU IF is restored upon CPU wake-up by the respective MCPM API consumers (ie CPU idle driver and suspend to RAM thread).

ARM: vexpress/TC2: add Serial Power Controller (SPC) support
The TC2 versatile express core tile integrates a logic block that provides the interface between the dual cluster test-chip and the M3 microcontroller that carries out power management. The logic block, called Serial Power Controller (SPC), contains several memory mapped registers to control among other things low-power states, wake-up irqs and per-CPU jump addresses registers. This patch provides a driver that enables run-time control of features implemented by the SPC power management control logic with an API to be used by different subsystem drivers on top. The SPC control logic is required to be programmed very early in the boot process to reset secondary CPUs on the TC2 testchip, set-up jump addresses and wake-up IRQs for power management. Hence, waiting for core changes to be made in the device core code to enable early registration of platform devices, the driver puts in place an early init scheme that allows kernel drivers to initialize the SPC driver directly from the components requiring it, if their initialization routine is called before this driver init function during the boot process. Device tree bindings documentation for the SPC component is also provided.

ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS.

ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle.
We normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time
we need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc cleanup
series because of interdependencies with timer drivers now moved out
of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes
for Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10.

Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core now
automatically populates supplied_from hierarchy from the device tree.
With these patches chargers and batteries can now lookup each other
without the board files support shim. Rhyland Klein at NVIDIA did the
work;
- New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the
AB85xx core and depends on some recent changes to it, so that is why the
driver comes through the battery tree. It has an appropriate ack from
the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
and Hongbo Zhang at Linaro authored the driver;
- Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes
touch mfd parts, but these were acked by the appropriate MFD maintainer
(i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
the submission process.
Minor changes, but still worth mentioning:
- Battery temperature reporting fix for Nokia N900 phones;
- Versatile Express poweroff driver moved into drivers/power/reset/.
- Tree-wise: use devm_kzalloc() where appropriate;
- Tree-wise: dev_pm_ops cleanups/fixes.

Merge tag 'for-v3.10' of git://git.infradead.org/battery-2.6
Pull battery updates from Anton Vorontsov:
"Highlights:
- OpenFirmware/DeviceTree support for the Power Supply core: the core
now automatically populates supplied_from hierarchy from the device
tree. With these patches chargers and batteries can now lookup
each other without the board files support shim. Rhyland Klein at
NVIDIA did the work
- New ST-Ericsson ABX500 hwmon driver. The driver is heavily using
the AB85xx core and depends on some recent changes to it, so that
is why the driver comes through the battery tree. It has an
appropriate ack from the hwmon maintainer (i.e. Guenter Roeck).
Martin Persson at ST-Ericsson and Hongbo Zhang at Linaro authored
the driver
- Final bits to sync AB85xx ST-Ericsson changes into mainline. The
changes touch mfd parts, but these were acked by the appropriate
MFD maintainer (ie Samuel Ortiz). Lee Jones at Linaro did most of
the work and lead the submission process.
Minor changes, but still worth mentioning:
- Battery temperature reporting fix for Nokia N900 phones
- Versatile Express poweroff driver moved into drivers/power/reset/
- Tree-wide: use devm_kzalloc() where appropriate
- Tree-wide: dev_pm_ops cleanups/fixes"

clk: vexpress: Add separate SP810 driver
Factor out the SP810 clocking code into a separate driver, selecting better (faster) parent at clk_prepare() time. This is to avoid problems with clocking infrastructure initialisation order, in particular to avoid dependency of fixed clock being initialized before SP810. It also makes vexpress platform OF-based clock initialisation code unnecessary.

ARM: vexpress: remove extra timer-sp control register clearing
The timer-sp initialization code clears the control register before initializing the timers, so every platform doing this is redundant. Signed-off-by: Rob Herring <rob.herring@calxeda.com> |
