From: Vijay Kumar B <vijayku...@zilogic.com> The default DMA offset is set to 3. When the property is not set by the consumer, the default causes DMA access to be shifted by 3 bytes. In PXA, this results in incorrect DMA access, leading to error notification in the USB controller driver. A better default would be 0, so that there is no offset, when the consumer does not specify one.
