From: Rob Herring Date: Thu, 26 May 2022 01:41:18 +0000 (-0500) Subject: dt-bindings: usb: snps,dwc3: Add missing 'dma-coherent' property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cdc46fa81cc00b8ae222f979320a14b902acc074;p=linux.git 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.
