Subject: [GIT PULL] irqchip updates for 5.10
Hi Thomas,
This is the rather large set of irqchip updates for 5.10.
This time around, we have three new drivers (MStar, Owl SIRQ and
PRUSS), some cross-architecture updates (the arm/arm64 switch to
standard IRQs for IPIs and the corresponding changes to their primary
irqchip drivers), a number of fixes as the fallout from these updates
(the Tegra bug is tasty), some driver updates (QC PDC, WD APB ICTL,
GIC...), and a couple of mundane bug fixes.
Please pull,
M.
The following changes since commit f4d51dffc6c01a9e94650d95ce0104964f8ae822:
Linux 5.9-rc4 (2020-09-06 17:11:40 -0700)
are available in the Git repository at:

Merge branch 'irq/mstar' into irq/irqchip-next (2020-10-10 12:46:54 +0100)
----------------------------------------------------------------
irqchip updates for Linux 5.10
Core changes:
- Allow irq retriggering to follow a hierarchy
- Allow interrupt hierarchies to be trimmed at allocation time
- Allow interrupts to be hidden from /proc/interrupts (IPIs)
- Introduce stub for set_handle_irq() when !GENERIC_IRQ_MULTI_HANDLER
- New per-cpu IPI handling flow
Architecture changes:
- Move arm/arm64 IPI handling to the core interrupt code, removing
the home brewed accounting
Driver updates:
- New driver for the MStar (and more recently Mediatek) platforms
- New driver for the Actions Owl SIRQ controller
- New driver for the TI PRUSS infrastructure
- Wake-up support for the Qualcomm PDC controller
- Primary interrupt controller support for the Designware APB ICTL
- Convert the IPI code for GIC, GICv3, hip04, armada-270-xp and bcm2836
to using standard interrupts
- Improve GICv3 pseudo-NMI support to deal with both non-secure and secure
priorities on arm64
- Convert the GIC/GICv3 drivers to using HW-based irq retrigger
- A sprinkling of dev_err_probe() conversion
- A set of NVIDIA Tegra fixes for interrupt hierarchy corruption
- A reset fix for the Loongson HTVEC driver
- A couple of error handling fixes in the TI SCI drivers
