usb: musb: fix order of conditions for assigning end point operations

2015-05-26T15:15:10+00:00

Currently we always assign one of the two common implementations of
ep_offset and ep_select operations, overwriting any platform-specific
implementations.

usb: musb: use new USB_RESUME_TIMEOUT

Make sure we're using the new macro, so our
resume signaling will always pass certification.

usb: musb: dsps: fix build on i386 when COMPILE_TEST is set

2015-04-03T17:09:53+00:00

Commit 3e457371f436 ("usb: musb: Fix fifo reads for dm816x with musb_dsps")
fixed a USB error on dm816x, but introduced a new build error on i386
when COMPILE_TEST is set:

drivers/usb/musb/musb_dsps.c: In function ‘dsps_read_fifo32’:
drivers/usb/musb/musb_dsps.c:624:3: error: implicit declaration of function
‘readsl’ [-Werror=implicit-function-declaration]
readsl(fifo, dst, len >> 2);

Let's fix this by using ioread32_rep() instead of readsl() as that's
more portable.

usb: patches for v4.1 merge window

As usual, a big pile of commits. This time a total
of 111 non-merge commits.

Other than the usual set of cleanups and non-critical
fixes, we have some interesting work for AM335x's MUSB
babble recovery. Now that takes a lot less time and we
don't have to Reset MUSB all the time.

The printer gadget has been converted to configfs interface
and the atmel udc has learned suspend/resume with wakeup.

usb: musb: Fix fifo reads for dm816x with musb_dsps

2015-03-24T16:36:38+00:00

Looks like dm81xx can only do 32-bit fifo reads like am35x. Let's set
up musb-dsps with a custom read_fifo function based on the compatible
flag.

Otherwise we can get the following errors when starting dhclient on a
asix USB Ethernet adapter:

asix 2-1:1.0 eth2: asix_rx_fixup() Bad Header Length 0xffff003c, offset 4

While at it, let's also remove pointless cast of the driver data.

usb: musb: cppi41: fix condition to call cppi41_trans_done().

2015-03-11T16:34:37+00:00

connect AR9271(USB wifi) to AM335x, and send a flood ping from Mac OSX,
AR9271 is stopped.

on USB bus, the following occurs.

 - OUT transaction is ACKed (NYET).
 - IN transaction is ACKed (512bytes).
 - PING-NAK transaction is continued for about 2 seconds (AR9271 timeout?).

In current imprementation, IN-transaction is not completed because it
checks the empty of TX-FIFO in cppi41_dma_callback().
As a result, communication to AR9271 stops.

This patch modified to check the empty of TX-FIFO only when OUT-transaction.

usb: musb: dsps: don't fake of_node to musb core

2015-03-11T15:19:35+00:00

If we pass our own of_node to musb_core, at least
pinctrl settings will be duplicated, meaning that
pinctrl framework will try to select default pin
state for musb_core when they were already requested
by musb-dsps.

A Warning will be printed however things will still
work.

musb shouldn't have of_node and phy phandle is passed
