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. Additionally, N real cascaded interrupts are implemented, instead of handling all input interrupts with one cascaded interrupt. Otherwise it is possible that the priority of the parent interrupts is not respected. Changes since v3: Link: https://lore.kernel.org/all/cover.1641739718.git.sander@svanheule.net/ - 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@svanheule.net/ - 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@svanheule.net/ - 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.
