Subject: [RESEND PATCH V4 1/5] dt-bindings: usb: tegra-xudc: Add dma-coherent for Tegra194
Date: Mon, 16 Jan 2023 15:19:13 +0000	[thread overview]
Message-ID: <20230116151917.94193-2-jonathanh@nvidia.com> (raw)
In-Reply-To: <20230116151917.94193-1-jonathanh@nvidia.com>

DMA operations for XUSB device controller are coherent for Tegra194 and
so update the device-tree binding to add this property.

Fixes: 394b012a422d ("dt-bindings: usb: tegra-xudc: Add Tegra194 XUSB controller support")
