Priority validation is not necessary because aic_common_irq_domain_xlate()
already handles it. With this removal, return type can be changed to void.Signed-off-by: Milo Kim

AIC IRQ fixup is handled in each IRQ chip driver.
It can be moved into aic_common_of_init() before returning the result.
Then, aic_common_irq_fixup() can be changed to static type.Signed-off-by: Milo Kim

Atmel AIC has common structure for SMR (Source Mode Register).
bit[6:5] Interrupt source type
bit[2:0] Priority level
Other bits are unused.To update new priority value, bit[2:0] should be cleared first and then
new priority level can be written. However, aic_common_set_priority()
helper clears source type bits instead of priority bits.
This patch fixes wrong mask bit operation.Fixes: b1479ebb7720 "irqchip: atmel-aic: Add atmel AIC/AIC5 drivers"

The struct irq_domain contains a "struct device_node *" field
(of_node) that is almost the only link between the irqdomain
and the device tree infrastructure.In order to prepare for the removal of that field, convert all
users to use irq_domain_get_of_node() instead.Signed-off-by: Marc Zyngier

This patch makes the bitmask for AIC_SRCTYPE consistent
with that of its valid values, and prevents the priority
field at bits 2:0 from being clobbered by an incorrect
AND with the AIC_SRCTYPE mask.Signed-off-by: Gavin Li

Pull irq core updates from Thomas Gleixner:
"This is the first (boring) part of irq updates:- support for big endian I/O accessors in the generic irq chip
- cleanup of brcmstb/bcm7120 drivers so they can be reused for non
ARM SoCs- the usual pile of fixes and updates for the various ARM irq chips"

First of all IRQCHIP_SKIP_SET_WAKE is not a valid irq_gc_flags and thus
should not be passed as the last argument of
irq_alloc_domain_generic_chips.Then pass the correct handler (handle_fasteoi_irq) to
irq_alloc_domain_generic_chips instead of manually re-setting it in the
initialization loop.And eventually initialize default irq flags to the pseudo standard:
IRQ_REQUEST | IRQ_PROBE | IRQ_AUTOEN.Signed-off-by: Boris Brezillon

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.Signed-off-by: Boris BREZILLON

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.Signed-off-by: Boris BREZILLON

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.Signed-off-by: Boris BREZILLON
