With the introduction of stacked domains, we have the issue that,
depending on where in the stack this is called, __irq_set_handler
will succeed or fail: If this is called from the inner irqchip,
__irq_set_handler() will fail, as it will look at the outer domain
as the (desc->irq_data.chip == &no_irq_chip) test fails (we haven't
set the top level yet).
This patch implements the following: "If there is at least one
valid irqchip in the domain, it will probably sort itself out".
This is clearly not ideal, but it is far less confusing then
crashing because the top-level domain is not up yet.

Add IRQ_SET_MASK_OK_DONE in addition to IRQ_SET_MASK_OK and
IRQ_SET_MASK_OK_NOCOPY to support stacked irqchip. IRQ_SET_MASK_OK_DONE
is the same as IRQ_SET_MASK_OK to irq core. To stacked irqchip, it means
that ascendant irqchips have done all the work and no more handling
needed in descendant irqchips.

We plan to use hierarchy irqdomain to suppport CPU vector assignment,
interrupt remapping controller, IO-APIC controller, MSI interrupt
and hypertransport interrupt etc on x86 platforms. So extend irqdomain
interfaces to support hierarchy irqdomain.
There are already many clients of current irqdomain interfaces.
To minimize the changes, we choose to introduce new version 2 interfaces
to support hierarchy instead of extending existing irqdomain interfaces.
According to Thomas's suggestion, the most important design decision is
to build hierarchy struct irq_data to support hierarchy irqdomain, so
hierarchy irqdomain related data could be saved in struct irq_data.
With support of hierarchy irq_data, we could also support stacked
irq_chips. This is most useful in case of set_affinity().
The new hierarchy irqdomain introduces following interfaces:
1) irq_domain_alloc_irqs()/irq_domain_free_irqs(): allocate/release IRQ
and related resources.
2) __irq_domain_alloc_irqs(): a special version to support legacy IRQs.
3) irq_domain_activate_irq()/irq_domain_deactivate_irq(): program
interrupt controllers to activate/deactivate interrupt.
There are also several help functions to ease irqdomain implemenations:
1) irq_domain_get_irq_data(): get irq_data associated with a specific
irqdomain.
2) irq_domain_set_hwirq_and_chip(): save irqdomain specific data into
irq_data.
3) irq_domain_alloc_irqs_parent()/irq_domain_free_irqs_parent(): invoke
parent irqdomain's alloc/free callbacks.
We also changed irq_startup()/irq_shutdown() to invoke
irq_domain_activate_irq()/irq_domain_deactivate_irq() to program
interrupt controller when start/stop interrupts.

mask/unmask_msi_irq and __mask_msi/msix_irq are PCI/MSI specific
functions and should be named accordingly. This is a preparatory patch
to support MSI on non PCI devices.
Rename mask/unmask_msi_irq to pci_msi_mask/unmask_irq and document the
functions. Provide conversion helpers.
Rename __mask_msi/msix_irq to __pci_msi/msix_desc_mask so its clear
that they operated on msi_desc. Fixup the only user outside of
pci/msi.

For example :
On i.mx6q-sabresd board, PMIC_ON_REQ connect with external
pmic ON/OFF pin, that will cause the whole PMIC powered off
except VSNVS. And system can restart once PMIC_ON_REQ goes

This patch adds links to the on-chip SRAM and reset controller nodes
and switches the interrupts. Make the BIT processor interrupt, which exists on
all variants, the first one. The JPEG unit interrupt, which does not exist on
i.MX27 and i.MX5 thus is an optional second interrupt.
Use different compatible strings for i.MX6Q/D and i.MX6S/DL, as they have to
load separate firmware images for some reason.

This adds more generic base device trees for Vybrid SoCs. There
are three series of Vybrid SoC commonly available:
- VF3xx series: single core, Cortex-A5 without external memory
- VF5xx series: single core, Cortex-A5
- VF6xx series: dual core, Cortex-A5/Cortex-M4
The second digit represents the presents of a L2 cache (VFx1x).
The VF3xx series are not suitable for Linux especially since the
internal memory is quite small (1.5MiB).
The VF500 is essentially the base SoC, with only one core and
without L1 cache. The VF610 is a superset of the VF500, hence
vf500.dtsi is then included and enhanced by vf610.dtsi. There is
no board using VF510 or VF600 currently, but, if needed, they can
be added easily.
The Linux kernel can also run on the Cortex-M4 CPU of Vybrid
using !MMU support. This patchset creates a device tree structure
which allows to share peripherals nodes for a VF6xx Cortex-M4
device tree too. The two CPU types have different views of the
system: Foremost they are using different interrupt controllers,
but also the memory map is slightly different. The base device
tree vfxxx.dtsi allows to create SoC and board level device trees
supporting the Cortex-M4 while reusing the shared peripherals
nodes.

The clock controller module (CCM) has several clock inputs, which
are connected to external crystal oscillators. To reflect this,
assign these fixed clocks to the CCM node directly.
This especially resolves initialization order dependencies we had
with the earlier initialization code: When resolving of the fixed
clocks failed in clk-vf610, the code created fixed clocks with a
rate of 0.
