usb: musb: gadget: clear TXPKTRDY flag when set FLUSHFIFO

2011-06-09T09:01:03+00:00

Fixes mis-use of MUSB's hardware feature where it won't
flush FIFOs when TXPKTRDY flag was set before and we are
flushing setting both FLUSHFIFO and TXPKTRDY.

In other words, we need to ensure that when we try to
flush FIFOs, we don't accidentaly set TXPKTRDY bit too
due to a read-back of the register.

The MUSB Programming Guide says "May be set simultaneously
with TxPktRdy to abort the packet that is currently being
loaded into the FIFO". This is a situation where TXPKTRDY
hasn't been set yet, but some data already loaded into the
fifo. It looks, that if TXPKTRDY has been set before, and
there is no loading in progress, but we set FLUSHFIFO with
the TXPKTRDY, controller tries to use the same logic to
abort loading and as the result just does nothing (because
there is no packet been loaded currently)

musb: fix prefetch build failure

2011-06-06T23:02:31+00:00

After the prefetch/list.h restructure, drivers need to explicitly include
linux/prefetch.h in order to use the prefetch() function.  Otherwise, the
current driver fails to build:

drivers/usb/musb/musb_core.c: In function 'musb_write_fifo':
drivers/usb/musb/musb_core.c:219: error: implicit declaration of function 'prefetch'
make[3]: *** [drivers/usb/musb/musb_core.o] Error 1

usb: musb: ux500: add ux500 specific code for gadget side

2011-05-18T11:43:13+00:00

Although U8500 and U5500 platforms use paltform dma, Inventra dma specific code
can work for them for the most part. Only difference is for the Rx path where
this patch is making use of request->short_not_ok to select dma mode.

usb: musb: host: remove duplicate check in musb_ep_program()

2011-05-13T11:34:07+00:00

musb_ep_program() contains obviously duplicate check for 'dma_channel' in its
IN/receive path -- removing it allows to save one level of indentation. While
at it, improve the comment style...
