Topic branch set up to facilitate merging the rest of the series which
removes the driver from arch code.
|
|
From local branch irqchip/gic, this is topic branch that was set up to
facilitate merging other changes depending on the new GICv3 driver.
|

Define SoCs that need irq fixups before enabling the AIC irqchip.
At the moment we're only fixing irq generated by the RTC block, but other
fixups will be added later on.

Provide an implementation to fix RTC irqs before enabling the irqchip.
This was previously done in arch/arm/mach-at91/sysirq_mask.c but as we're
trying to use standard implementation (IRQCHIP_DECLARE and automatic call
of irqchip_init within arch/arm/kernel/irq.c) we need to do those fixups
in the irqchip driver.

Add irq fixup infrastructure to handle IP blocks connected to shared irqs
that are left in an unknown state when booting the kernel.
In this case the IP block which has not masked its interrupt and has no
driver loaded (either because it is not compiled or because it is not
loaded yet) might generate spurious interrupts when another IP block
request the shared irq.
A good example of this case is the RTC block on which register configs are
kept even after a shutdown (if a proper VDDcore is supplied), and thus
might generate spurious interrupts when the platform is switched on.

Add AIC (Advanced Interrupt Controller) and AIC5 (AIC5 is an evolution of
the AIC block) drivers.
Put common code in irq-atmel-aic-common.c/.h so that both driver can access
shared functions (this will ease maintenance).
These drivers are only compatible with dt enabled board and replace the
old implementation found in arch/arm/mach-at91/irq.c.

The Generic Interrupt Controller (version 3) offers services that are
similar to GICv2, with a number of additional features:
- Affinity routing based on the CPU MPIDR (ARE)
- System register for the CPU interfaces (SRE)
- Support for more that 8 CPUs
- Locality-specific Peripheral Interrupts (LPIs)
- Interrupt Translation Services (ITS)
This patch adds preliminary support for GICv3 with ARE and SRE,
non-secure mode only. It relies on higher exception levels to grant ARE
and SRE access.
Support for LPI and ITS will be added at a later time.

A few GICv2 low-level function are actually very useful to GICv3,
and it makes some sense to share them across the two drivers.
They end-up in their own file, with an additional parameter used
to ensure an optional synchronization (unused on GICv2).

In addition to consolidating the or1k-pic with other interrupt
controllers, this makes OpenRISC less tied to its on-cpu
interrupt controller.
All or1k-pic specific parts are moved out of irq.c and into
drivers/irqchip/irq-or1k-pic.c
In that transition, the functionality have been divided into
three chip variants.
One that handles level triggered interrupts, one that handles edge
triggered interrupts and one that handles the interrupt
controller that is present in the or1200 OpenRISC cpu
implementation.

On certain platforms such as DRA7, SPIs 0, 1, 2, 3, 5, 6, 10, 131,
132, 133 are direct wired to hardware blocks bypassing crossbar.
This quirky implementation is *NOT* supposed to be the expectation
of crossbar hardware usage. However, these are already marked in our
description of the hardware with SKIP and RESERVED where appropriate.
Unfortunately, we need to be able to refer to these hardwired IRQs.
So, to request these, crossbar driver can use the existing information
from it's table that these SKIP/RESERVED maps are direct wired sources
and generic allocation/programming of crossbar should be avoided.

crossbar mapping
Currently we attempt to map any crossbar value to an IRQ, however,
this is not correct from hardware perspective. There is a max crossbar
event number upto which hardware supports. So describe the same in
device tree using 'ti,max-crossbar-sources' property and use it to
validate requests.
[ jac - remove MAX_SOURCES from binding doc, use integer because we
shouldn't put implementation details in the binding docs ]

Reverse the search algorithm to ensure that address mapping and IRQ
allocation logics are proper. This makes the below bugs visible sooner.
class 1. address space errors -> example:
reg = <a size_b>
ti,max-irqs = is a wrong parameter
class 2: irq-reserved list - which decides which entries in the
address space is not actually wired in
class 3: wrong list of routable-irqs.
In general allocating from max to min tends to have benefits in
ensuring the different issues that may be present in dts is easily
caught at definition time, rather than at a later point in time.

Since crossbar is s/w configurable, the initial settings of the
crossbar cannot be assumed to be sane. This implies that:
a) On initialization all un-reserved crossbars must be initialized to
a known 'safe' value.
b) When unmapping the interrupt, the safe value must be written to
ensure that the crossbar mapping matches with interrupt controller
usage.
So provide a safe value in the dt data to map if
'0' is not safe for the platform and use it during init and unmap
While at this, fix the below checkpatch warning.

Until now, the irq-armada-370-xp irqchip driver was not masking all
interrupts at initialization. While in most cases this is not a
problem because the bootloader has probably masked all interrupts, it
becomes a problem when you use kexec: you're in kernel A, with many
interrupts enabled, and then kexec into kernel B, without going
through the bootloader. So during the boot process, if an interrupt
occurs while the corresponding driver has not been loaded, you would
get spurious interrupts.
This commit fixes that by ensuring all interrupts are properly masked
when the irqchip driver is initialized. Note that interrupt masking
takes place at two level: at the global level (main_int_base) and at
the per-CPU level (per_cpu_int_base).

Pull NVMe update from Matthew Wilcox:
"Mostly bugfixes again for the NVMe driver. I'd like to call out the
exported tracepoint in the block layer; I believe Keith has cleared
this with Jens.
We've had a few reports from people who're really pounding on NVMe
devices at scale, hence the timeout changes (and new module
parameters), hotplug cpu deadlock, tracepoints, and minor performance
tweaks"
[ Jens hadn't seen that tracepoint thing, but is ok with it - it will
end up going away when mq conversion happens ]

Pull GPIO fix from Linus Walleij:
"A first GPIO fix for the v3.16 series, this was serious since it
blocks the OMAP boot.
Sending you this vital fix before leaving for a short vacation so it
does not sit collecting dust in my tree for no good reason.
Apart from this, our v3.16 cycle looks like a good start"
