Subject: [Patch 13/16] media: ti-vpe: vpdma: Use fixed type for address in descriptor
Date: Fri, 27 Sep 2019 13:36:47 -0500	[thread overview]
Message-ID: <20190927183650.31345-14-bparrot@ti.com> (raw)
In-Reply-To: <20190927183650.31345-1-bparrot@ti.com>

Using dma_addr_t as the type to hold address inside of a fix sized
descriptor used by the vpdma firmware is prone to fail when the expected
width is 32 bits and suddenly when CONFIG_LPAE is enabled the data size
is now 64 bits shifted the remaining members of the descriptor in memory
which confuses the firmware.
