Subject: [PATCH v2 5/5] PCI: keystone: Set DMA mask and coherent DMA mask
Date: Fri, 26 Nov 2021 14:01:19 +0530	[thread overview]
Message-ID: <20211126083119.16570-6-kishon@ti.com> (raw)
In-Reply-To: <20211126083119.16570-1-kishon@ti.com>

Set DMA mask and coherent DMA mask such to indicate the device
can address the entire address space (32-bit in the case of
K2G and 48-bit in the case of AM654).
