Subject: [PATCH V5 1/5] dt-bindings: usb: tegra-xudc: Add dma-coherent for Tegra194
Date: Thu, 19 Jan 2023 10:42:04 +0000 [thread overview]
Message-ID: <20230119104208.28726-2-jonathanh@nvidia.com> (raw)
In-Reply-To: <20230119104208.28726-1-jonathanh@nvidia.com>
DMA operations for XUSB device controller are coherent for Tegra194 and
so update the device-tree binding to add this property.
