Hi Thomas,

Here's the set of updates from the irqchip department for 5.14.

The bulk of it is a change in the way irqdomain works, now
consistently caching an irqdata instead of a mix of irq numbers and
irqdata. This allows us to simplify the handling of IRQ handling
involving an irqdomain as we can shorten the lookup path.

All the irqchip drivers are updated to this new API when possible. I
have a lot more on the back-burner (GPIO, pinctl, PCI...), but let's
get the fundamentals in first.

Note that this has some impacts on some architectures and
arch-specific drivers (PowerPC and MIPS, mainly), mostly because of
some circular include hell.

Other than that, a couple of driver updates, the usual DT churn, and a
few printk cleanup patches.

Please pull,

M.

----------------------------------------------------------------
irqchip updates for 5.14

- Revamped the irqdomain internals to consistently cache an irqdata

- Expose a new API to simplify IRQ handling involving an irqdomain by
not using the IRQ number

- Convert all the irqchip drivers to this new API

- Allow the Qualcomm PDC driver to be compiled as a module

- Fix HiSi MBIGEN compile warning when CONFIG_ACPI isn't selected

- Remove a bunch of spurious printks on error paths

- The obligatory couple of DT updates
