From 0ab8d0f6ae3f1234e38eaedc3ff7c22bfdf7f78c Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Wed, 29 Sep 2021 17:38:34 +0100 Subject: irqdomain: Make of_phandle_args_to_fwspec() generally available of_phandle_args_to_fwspec() can be generally useful to code extracting a DT of_phandle and using an irq_fwspec to use the hierarchical irqdomain API. Make it visible to the rest of the kernel, including modules.

This allows the Link-up/Link-down interrupts to be wired, allowing the bring-up to be synchronised (and provide debug information). The framework can further be used to handle the rest of the per port events if and when necessary. Likewise, INTx signalling is implemented so that end-points can actually be used.
