[GIT PULL] irqchip updates for 5.9

[GIT PULL] irqchip updates for 5.9

[Marc Zyngier]

Hi Thomas,

Here's the irqchip updates for 5.9. Although it is rather large this
time around, it is mostly a collection of random cleanups and minor
improvements. The most notable additions is a set of helpers for
platform irqchip drivers to be built as modules.

I may have a second pull request later if the TI folks can sort their
dependency nightmare, but don't hold your breath.

Please pull,

	M.

----------------------------------------------------------------
irqchip updates for Linux 5.9

- Add infrastructure to allow DT irqchip platform drivers to
  be built as modules
- Allow qcom-pdc, mtk-cirq and mtk-sysirq to be built as module
- Fix ACPI probing to avoid abusing function pointer casting
- Allow bcm7120-l2 and brcmstb-l2 to be used as wake-up sources
- Teach NXP's IMX INTMUX some power management
- Allow stm32-exti to be used as a hierarchical irqchip
- Let stm32-exti use the hw spinlock API in its full glory
- A couple of GICv4.1 fixes
- Tons of cleanups (mtk-sysirq, aic5, bcm7038-l1, imx-intmux,
  brcmstb-l2, ativic32, ti-sci-inta, lonsoon, MIPS GIC, GICv3)
