Subject: [RESEND PATCH V4 2/5] arm64: tegra: Add dma-coherent property for Tegra194 XUDC
Date: Mon, 16 Jan 2023 15:19:14 +0000 [thread overview]
Message-ID: <20230116151917.94193-3-jonathanh@nvidia.com> (raw)
In-Reply-To: <20230116151917.94193-1-jonathanh@nvidia.com>
DMA operations for XUSB device controller (XUDC) are coherent for
Tegra194 and so add the 'dma-coherent' property for this device.
Fixes: bc8788b2f3a0 ("arm64: tegra: Add XUDC node on Tegra194")
