The original implementation for this interrupt controller/router used an interrupt-map parser to determine which parent interrupts were present. However, this controller is not transparent, so a list of parent interrupts seems more appropriate, while also getting rid of the assumed routing to parent interrupts. Changes since v5: Link: https://lore.kernel.org/all/cover.1644864700.git.sander@xxxxxxxxxxxxx/ - Allow interrupt-map for new compatibles, but mark as deprecated - Change back to single-cell interrupt specifiers - Drop patch adding a domain for every output line Changes since v4: Link: https://lore.kernel.org/all/cover.1644165421.git.sander@xxxxxxxxxxxxx/ - Add Rob's Reviewed-by - Use irq_domain_add_linear instead of irq_domain_add_simple - Drop 'inline' specifiers from static functions - Drop WARN in intc_select() to only warn once for old bindings Changes since v3: Link: https://lore.kernel.org/all/cover.1641739718.git.sander@xxxxxxxxxxxxx/ - Patches with fixes were merged, so these are no longer included. - Update the devicetree changes to more clearly indicate the controller is not transparent. Changes since v2 (RFC): Link: https://lore.kernel.org/all/cover.1640548009.git.sander@xxxxxxxxxxxxx/ - Define new, two-part compatibles for devicetree bindings. The existing format is kept for the old one-part compatible, but deprecated. New compatibles will require a different way of specifying parent interrupts and interrupt routing. - Add change to handle all pending SoC interrupts in one go. Changes since v1 (RFC): Link: https://lore.kernel.org/all/cover.1640261161.git.sander@xxxxxxxxxxxxx/ - Split some of the changes to limit the patch scope to one issue. - Dropped some small (spurious or unneeded) changes - Instead of dropping/replacing interrupt-map, the last patches now provide an implementation that amends the current situtation.
