Subject[GIT PULL] irqchip updates for Linux 5.8
Date
Hi Thomas,

Here is this merge window's crop of irqchip/irqdomain updates, a
pretty quiet one (which nobody will complain about).

On the menu this time, a handful of MIPS drivers, some welcome
cleanups for irqdomain and irq_sim, the long overdue fixes for GICv3
ITS LPI balancing and managed MSIs, a set of fixes for the rather
experimental multi-PLIC setup, and various cleanups.

Note that the irq_sim updates change files in the IIO and GPIO
subsystem, for which the respective maintainers have given their Ack.

Please pull,

M.

dt-bindings: interrupt-controller: Add Loongson PCH MSI (2020-05-29 09:42:19 +0100)

----------------------------------------------------------------
irqchip updates for Linux 5.8:

- A few new drivers for the Loongson MIPS platform (HTVEC, PIC, MSI)
- A cleanup of the __irq_domain_add() API
- A cleanup of the IRQ simulator to actually use some of
the irq infrastructure
- Some fixes for the Sifive PLIC when used in a multi-controller
context
- Fixes for the GICv3 ITS to spread interrupts according to the
load of each CPU, and to honor managed interrupts
- Numerous cleanups and documentation fixes
