[PATCH v4 0/2] Amazon's Annapurna Labs Fabric Interrupt Controller

[Talel Shenhar]

This series introduces support for Amazon's Annapurna Labs Fabric Interrupt
Controller.

The Amazon's Annapurna Labs FIC (Fabric Interrupt Controller) has 32
inputs/sources. This FIC may be cascaded into another FIC or connected
directly to the main CPU Interrupt Controller (e.g. GIC).

Changes since v3:
=================
- tightened the verification for supported trigger types
- updated dt-binding's example to meet the binding description
  (interrupt-cells to 2)
- added description to interrupt-cells to explain each field
- changed pr_err to pr_debug inside al_fic_irq_set_type in order to allow
  the user to enable printouts for verbose information in case of errors

Changes since v2:
=================
- updated dt-bindings to use proper format for entry name
- removed kernel-doc format style from Copyright
- removed unneeded/misplaced selects from Kconfig
- changed used mmio operation to relaxed flavor
- changed error return value from EPERM to EINVAL int case of attempting to
  reconfigure the FIC after it has been configured
- fixed commenting format
- used drivers define instead of subsystem internals
- moved al_fic_hw_init function to caller
- removed al_fic_wire_get_domain from documentation
- removed argument validation from al_fic_wire_init

Changes since v1:
=================
- removing unused exported APIs
- updating cover letter and commit message accordingly
