From 77e0ddf097d6d4ceaf898e088b133b99e0a97fa0 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Mon, 28 Aug 2023 17:29:46 +0200 Subject: parisc: ccio-dma: Create private runway procfs root entry Create an own procfs "runway" root entry for the CCIO driver. No need to share it with the sba_iommu driver, as only one of those busses can be active in one machine anyway.
