Subject: [PATCH v4 4/6] ata: ahci_imx: Add 32bits DMA limit for i.MX8QM AHCI SATA
Date: Fri, 19 Jul 2024 13:42:14 +0800 [thread overview]
Message-ID: <1721367736-30156-5-git-send-email-hongxing.zhu@nxp.com> (raw)
In-Reply-To: <1721367736-30156-1-git-send-email-hongxing.zhu@nxp.com>
Since i.MX8QM AHCI SATA only has 32bits DMA capability.
Add 32bits DMA limit here.
