Merge tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull irq updates from Thomas Gleixner:
"The interrupt departement provides:

- A mechanism to shield isolated tasks from managed interrupts:

The affinity of managed interrupts is completely controlled by the
kernel and user space has no influence on them. The reason is that
the automatically assigned affinity correlates to the multi-queue
CPU handling of block devices.

If the generated affinity mask spaws both housekeeping and isolated
CPUs the interrupt could be routed to an isolated CPU which would
then be disturbed by I/O submitted by a housekeeping CPU.

The new mechamism ensures that as long as one housekeeping CPU is
online in the assigned affinity mask the interrupt is routed to a
housekeeping CPU.

If there is no online housekeeping CPU in the affinity mask, then
the interrupt is routed to an isolated CPU to keep the device queue
intact, but unless the isolated CPU submits I/O by itself these
interrupts are not raised.

- A small addon to the device tree irqdomain core code to avoid
duplication in irq chip drivers

- Conversion of the SiFive PLIC to hierarchical domains

- The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI,
NXP INTMUX, Meson A1 GPIO

- The first cut of support for the new ARM GICv4.1

- The usual pile of fixes and improvements in core and driver code"

The specific problem here is that the mbigen driver real probe has failed
as the mbigen_of_create_domain()->of_platform_device_create() call fails,
the reason for that being that we never destroyed the platform device
created during the remove test dry run and there is some conflict.

Since we generally would never want to unbind this driver, and to save
adding a driver tear down path for that, just set the driver
.suppress_bind_attrs member to avoid this possibility.
