usb:gadget: Refcount for gadget pullup
This commit fixes the way gadget's pullup method (wrapped at
usb_gadget_connect/disconnect) is called in the udc-core.
The composite driver allows correct driver registration, even when it calls
the usb_gadget_disconnect method (composite driver configuration is defered
for user space - please look into the description of usb_composite_probe at
composite.c - line: 1623)
One such example is the CCG (Configurable Composite Gadget) driver (at
drivers/staging/ccg), which after its registration has no usb descriptor
(i.e. idProduct, idVendor etc.) and functions registered. Those are configured
after writing to /sys/module/g_ccg/parameters/ or /sys/class/ccg_usb/ccg0/.
Unfortunately, the code at 'usb_gadget_probe_driver' method (some code omitted):
if (udc_is_newstyle(udc)) {
bind(udc->gadget);
usb_gadget_udc_start(udc->gadget, driver);
usb_gadget_connect(udc->gadget);
}
Explicitly calls the usb_gadget_connect method for this driver. It looks like
the udc-core enables pullup for a driver, which has no functions and no
descriptor filled (those values are feed from userspace).
The USB composite driver API allows correct driver registration with calling
usb_gadget_disconnect method, but as it is now, _ALL_ newstyle usb gadgets are
connected by default. Therefore it violates the composite API.
The solution (at least until the udc-core is reworked) is to add atomic
variable, which helps in balancing the number of called usb_gadget_connect/
disconnect functions.

dma: pl330: Fix handling of TERMINATE_ALL while processing completed descriptors
The pl330 DMA driver is broken in regard to handling a terminate all request
while it is processing the list of completed descriptors. This is most visible
when calling dmaengine_terminate_all() from within the descriptors callback for
cyclic transfers. In this case the TERMINATE_ALL transfer will clear the
work_list and stop the transfer. But after all callbacks for all completed
descriptors have been handled the descriptors will be re-enqueued into the (now
empty) work_list. So the next time dma_async_issue_pending() is called for the
channel these descriptors will be transferred again which will cause data
corruption. Similar issues can occur if dmaengine_terminate_all() is not called
from within the descriptor callback but runs on a different CPU at the same time
as the completed descriptor list is processed.
This patch introduces a new per channel list which will hold the completed
descriptors. While processing the list the channel's lock will be held to avoid
racing against dmaengine_terminate_all(). The lock will be released when calling
the descriptors callback though. Since the list of completed descriptors might
be modified (e.g. by calling dmaengine_terminate_all() from the callback) we can
not use the normal list iterator macros. Instead we'll need to check for each
loop iteration again if there are still items in the list. The drivers
TERMINATE_ALL implementation is updated to move descriptors from both the
work_list as well the new completed_list back to the descriptor pool. This makes
sure that none of the descripts finds its way back into the work list and also
that we do not call any futher complete callbacks after
dmaengine_terminate_all() has been called.

dmaengine: make dma_submit_error() return an error code
The problem here is that the dma_xfer() functions in
drivers/ata/pata_arasan_cf.c and drivers/mtd/nand/fsmc_nand.c expect
dma_submit_error() to return an error code so they return 1 when they
intended to return a negative.
So far as I can tell, none of the ->tx_submit() functions ever do
return error codes so this patch should have no effect in the current
code.
I also changed it from a define to an inline.

dma: pl330: Implement device_slave_caps
Implement the device_slave_caps() callback for the pl330 driver. This allows
dmaengine users like the generic ALSA dmaengine PCM driver to query the
capabilities of the driver. The PL330 supports all buswidths and both
mem-to-dev as well as dev-to-mem transfers. In theory there is no limit on the
number of segments that can be transferred (in practice you'll run out of memory
eventually) and the number of bytes per segment is limited by the size of the
PL330 program buffer. Due to the nature of the PL330 the maximum number of bytes
per segment depends on the burstsize, the driver sets it to the value for a
1-byte burstsize, since it is the smallest.
