From 17de3f5fdd35676b0e3d41c7c9bf4e3032eb3673 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 21 Nov 2023 18:04:02 +0000 Subject: iommu: Retire bus ops With the rest of the API internals converted, it's time to finally tackle probe_device and how we bootstrap the per-device ops association to begin with. This ends up being disappointingly straightforward, since fwspec users are already doing it in order to find their of_xlate callback, and it works out that we can easily do the equivalent for other drivers too. Then shuffle the remaining awareness of iommu_ops into the couple of core headers that still need it, and breathe a sigh of relief. Ding dong the bus ops are gone! CC: Rafael J.
