From de9f8a91eb32bb79149c4fc790df3b54ae710d18 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Tue, 16 Aug 2022 18:28:03 +0100 Subject: iommu/dma: Clean up Kconfig Although iommu-dma is a per-architecture chonce, that is currently implemented in a rather haphazard way. Selecting from the arch Kconfig was the original logical approach, but is complicated by having to manage dependencies; conversely, selecting from drivers ends up hiding the architecture dependency *too* well. Instead, let's just have it enable itself automatically when IOMMU API support is enabled for the relevant architectures. It can't get much clearer than that.
