From d6ff10e072e1150a9a135e355b1f85479609bab2 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Thu, 12 Aug 2021 16:17:12 +0200 Subject: [PATCH] arm64: tegra: Add missing interconnects property for USB on Tegra186 The device tree node for the XUDC (USB device mode controller) is missing the interconnects property that describes the path to memory for the controller. Add the property so that the things like the DMA mask can be set by the operating system.
