From a6a86473350c7dcbae61afa1e926941d76ca17ed Mon Sep 17 00:00:00 2001 From: Laurentiu Tudor Date: Thu, 20 Sep 2018 13:46:54 +0300 Subject: [PATCH] arm64: dts: ls104x: use a pseudo-bus to constrain usb dma size Wrap the usb controllers in an intermediate simple-bus and use it to constrain the dma address size of these usb controllers to the 40 bits that they generate toward the interconnect. This is required because the SoC uses 48 bits address sizes and this mismatch would lead to smmu context faults because the usb generates 40-bit addresses while the smmu page tables are populated with 48-bit wide addresses.
