Subject: [PATCH v2 00/14][treewide] irqdomain: Simplify interrupt handling
Now that the core patches for generic_handle_domain_irq() have made it
into the core code (see [1]), this series goes over the tree to
simplify the interrupt handling by directly using the irq_data that is
now stored in the IRQ domain.
In summary, anything of the form:
- generic_handle_irq(irq_find_mapping(domain, hwirq)) or
- generic_handle_irq(irq_linear_revmap(domain, hwirq))
is turned into generic_handle_domain_irq(domain, hwirq), which deals
with the gory details.
This series goes over a number of subsystems and architectures, and
also adds a bit of documentation. For those of you wondering about a
merge strategy, all the patches should be independent. Maintainers can
either pick them up themselves, or give me an Ack so that I can take
them via the irqchip tree. Just let me know.
I have an extra set of patches dealing with nested interrupts, but
that still needs to mature a bit.
* From v1 [1]:
- Merged all the preliminary patches and core support
- Caught up with a few extra users in 5.14
- Picked up ABs, RBs, with thanks
- Rebased on top of v5.14-rc4
