From cdc46fa81cc00b8ae222f979320a14b902acc074 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 25 May 2022 20:41:18 -0500 Subject: dt-bindings: usb: snps,dwc3: Add missing 'dma-coherent' property The 'unevaluatedProperties' schema checks is not fully working and doesn't catch some cases where there's a $ref to another schema. A fix is pending, but results in new warnings in examples. Some DWC3 implementations such as Xilinx are hooked up coherently and need to set the 'dma-coherent' property.
