1f1307e1d6 doc: enhance multi-level interrupts diagram
Make the multi-level interrupts diagram more clear by saying:

  - the "-" means an interrupt slot
  - all interrupt slots are numbered from 0 starting from right most
  - alphabets denote devices
  - add an example chain for device D

1e6adba9ef drivers/interrupt_controller: Introduce multi-level interrupt support
In a scenario where a platform harbours multiple interrupts to the
extent the core cannot support it, an interrupt controller is added
as an additional level of interrupt. It typically combines several
sources of interrupt into one line that is then routed to the parent
controller.

4fc96066b0 irq: introduce 'direct' interrupt API definition
These interrupts are for ISRs that need the lowest possible latency.
They do not take parameters and are installed directly in the interrupt
vector table.
