Without this patch you will get an error "gpio-export probe deferral
not supported" when you try to export i2c expander gpio pins.
gpio-export is probed long before i2c-bus and i2c expander are created
and it doesn't retry it so none pins are exported.

In the new DT-based pci-ar71xx driver, ar71xx_pci_irq_init() was being
called before populating the PCI controller's device_node struct member.
This led to no IRQ being assigned to connected PCI devices (e.g. ath9k
cards) and caused them to be non-functional aside from simply being
detected.
The previous errors encountered in dmesg were: "irq: no irq domain found
for /ahb/apb/pcie-controller@180c0000 !". /proc/interrupts listed an IRQ
of 0 for the cards.
While this has been only been tested on a yet-to-be-merged RouterStation
Pro target, it should also fix the broken wifi people have reported for
the ath79 WNDR3800 target.

Check if the GPIO is valid (or set at all). If no GPIO is set in the
devicetree, a gpiolib related kernel warning + stacktrace is shown during
boot and gpio-export reports GPIOs as exported albeit none really is.

Add the missing enable and disable function.
Remove dummy mask and unmask function and use the one provided by
irq_dummy_chip.
Allow interrupt status register being defined from dts.
Add ddr_wb_flush for ar934x/qca953x.
Rename controller name to qca,ar9340-intc because this design was
first introduced in AR934x.

Add support for the common led property "linux,default-trigger". It
allows to set a default led trigger via devicetree.

This target aims to replace ar71xx mid-term. The big part that is still
missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik
subtargets will follow.
