21edf50948 Updates for the interrupt subsystem:
Core changes:
 
   - Cleanup and simplification of common code to invoke the low level
     interrupt flow handlers when this invocation requires irqdomain
     resolution. Add the necessary core infrastructure.
 
   - Provide a proper interface for modular PMU drivers to set the
     interrupt affinity.
 
   - Add a request flag which allows to exclude interrupts from spurious
     interrupt detection. Useful especially for IPI handlers which always
     return IRQ_HANDLED which turns the spurious interrupt detection into a
     pointless waste of CPU cycles.
 
 Driver changes:
 
   - Bulk convert interrupt chip drivers to the new irqdomain low level flow
     handler invocation mechanism.
 
   - Add device tree bindings for the Renesas R-Car M3-W+ SoC
 
   - Enable modular build of the Qualcomm PDC driver
 
   - The usual small fixes and improvements.

IRQF_NO_AUTOEN flag doesn't go well with IRQF_SHARED flag - the
check in request_threaded_irq fails and exits with EINVAL.

So we ignore the flag and enable it on the first IRQ request. No
interrupt should arrive from the chip as all interrupts are masked
by default.

This seems to have started with commit 4d8bde883bfb ("OF: Don't set
default coherent DMA mask"). We have the parent SPI controller use
DMA, while CPCAP driver and it's children do not. For audio, the
DMA is handled over I2S bus with the McBSP driver.

33d550701b mfd: arizona: Allow building arizona MFD-core as module
There is no reason why the arizona core,irq and codec model specific
regmap bits cannot be build as a module. All they do is export symbols
which are used by the arizona-spi/i2c and arizona-codec modules, which
themselves can be built as module.

Change the Kconfig and Makefile arizona bits so that the arizona MFD-core
can be built as a module.

This is especially useful on x86 platforms with a WM5102 codec, this
allows the arizona MFD driver necessary for the WM5102 codec to be
enabled in generic distro-kernels without growing the base kernel-image
size.

Note this also adds an explicit "depends on MFD_ARIZONA" to all the
arizona codec Kconfig options. The codec drivers use functions from mfd
arizona-core. These new depends are necessary to disallow the codec
drivers being builtin when the arizona-core is build as a module,
otherwise we end up with missing symbol errors when building vmlinuz.

3efc465f91 mfd: axp20x: Allow AXP 806 chips without interrupt lines
Currently the AXP chip requires to have its IRQ line connected to some
interrupt controller, and will fail probing when this is not the case.

On a new Allwinner SoC (H616) there is no NMI pin anymore, and at
least one board does not connect the AXP's IRQ pin to anything else,
so the interrupt functionality of the AXP chip is simply not available.

Check whether the interrupt line number returned by the platform code is
valid, before trying to register the irqchip. If not, we skip this
registration, to avoid the driver to bail out completely.
Also we need to skip the power key functionality, as this relies on
a valid IRQ as well.
