In sama5d3 SoC, there are 16 endpoints, which is different with
earlier SoCs (only have 7 endpoints). The USBA_NR_ENDPOINTS micro

On 19/02/2014 03:07, Bo Shen :
The SoCs earlier than sama5d3, they have the same number endpoints
and DMA channels. In driver code, they use the same definition
USBA_NR_ENDPOINTS for both endpoints and dma channels. However,
in sama5d3, it has different number for endpoints and DMA channels.
