Subject: [PATCH 3/3] scsi: ufs: Enable DMA clustering
Date: Fri,  6 Jan 2023 13:58:00 -0800	[thread overview]
Message-ID: <20230106215800.2249344-4-bvanassche@acm.org> (raw)
In-Reply-To: <20230106215800.2249344-1-bvanassche@acm.org>

All UFS host controllers support DMA clustering. Hence enable DMA
clustering.

Note: without patch "Exynos: Fix the maximum segment size", this patch
breaks support for the Exynos controller.
