5202ef942f Move qemu_irq typedef out of qemu-common.h
It's necessary for making CPU child of DEVICE without
causing circular header deps.

1e5b31e6bd qdev: allow multiple qdev_init_gpio_in() calls
Allow multiple qdev_init_gpio_in() calls for the one device. The first call will
define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled
with different handlers. Needed when two levels of the QOM class heirachy both
define GPIO functionality, as a single GPIO handler with an index selecter is
not possible.

2028834574 qtest: IRQ interception infrastructure
Since /i440fx/piix3 is being removed from the composition tree, the
IO-APIC is placed under /i440fx.  This is wrong and should be changed
as soon as the /i440fx/piix3 path is put back.

22ec3283ef irq: introduce qemu_irq_proxy()
In some cases we have a circular dependency involving irqs - the irq
controller depends on a bus, which in turn depends on the irq controller.
Add qemu_irq_proxy() which acts as a passthrough, except that the target
irq may be set later on.

9793212bb0 hw/irq: Add qemu_irq_split() so one GPIO output can feed two inputs
Add a qemu_irq_split() function which allows a board to wire a single
GPIO output up to two GPIO inputs. This is needed for realview boards,
where the MMC card status is visible both in a system register and
via a PL061 GPIO module.
