3.13.11-ckt16 -stable review patch. If anyone has any objections, please let
me know.
------------------
From: Bo Shen <voice.s...@atmel.com>
commit f40afdddeb6c54ffd1e2920a5e93e363d6748db6 upstream.
According to the datasheet, when transfer using DMA, the control
setting for IN packet only need END_BUF_EN, END_BUF_IE, CH_EN,
while for OUT packet, need more two bits END_TR_EN and END_TR_IE
to be configured.
