Subject: media: ti-vpe: Set the DMA mask and coherent mask
Author: Benoit Parrot <bpar...@ti.com>
Date: Mon Oct 7 12:10:03 2019 -0300
VPE uses VPDMA (built-in dma engine) to transfer data to and from the IP
and memory. VPDMA expect 32 bits addresses. To make sure that is always
the case set the DMA mask and coherent mask for the device.
