usb: dwc3: use proper function for setting endpoint name

2012-04-02T16:52:29+00:00

commit 27a78d6a283d6782438f72306746afe4bf44c215 upstream.

It's wrong to use the size of array as an argument for strncat.
Memory corruption is possible. strlcat is exactly what we need here.

usb: dwc3: fix bogus test in dwc3_gadget_start_isoc

2012-04-02T16:52:29+00:00

commit 9bafa56c7cee5c6fa68de5924220abb220c7e229 upstream.

Zero is a valid value for a microframe number. So remove the bogus
test for non-zero in dwc3_gadget_start_isoc().

usb: dwc3: ep0: tidy up Pending Request handling

2012-02-03T17:22:04+00:00

commit 68d8a781575d7be490f97eb2c403fb13b083da6a upstream.

The way our code was written, we should never have
a DWC3_EP_PENDING_REQUEST flag set out of a Data Phase
and the code in __dwc3_gadget_ep0_queue() did not
reflect that situation properly.

Tidy up that case to avoid any possible mistakes
when starting requests for IRQs which are long
gone.

usb: dwc3: core: fix cached revision on our structure

2011-12-14T19:59:30+00:00

All our revision macros are defined with the entire
32-bits which we read from GSNPSID register, so we
must cache all 32-bits properly rather than masking
the top 16-bits.

This will fix all revision checks we have on current
driver.

usb: dwc3: gadget: initialize max_streams

2011-11-14T19:51:31+00:00

Without this the gadget will never be able to allocate a stream capable
endpoint. The manual says that the stream id is a 16bit id. It does not
talk about an upper limit in any other way. So I think 15 is a
reasonable limit :)

usb: Add module.h to various dwc3 drivers

2011-10-04T17:27:28+00:00

These files uses the full set of MODULE_ macros and so need to
include module.h directly.

usb: dwc3: convert structures into bitshifts

2011-10-04T17:25:56+00:00

our parameter structures need to be written to
HW, so instead of assuming little endian, we
convert those into bit shifts.

usb: dwc3: gadget: allow clock gating to work

2011-10-04T17:25:56+00:00

The dwc3 core has internal clock gating support.

Let's allow that to happen by clearing the disable
bit in GCTL register.

usb: dwc3: add struct dwc3_hwparams

That structure will hold a copy of readonly
GHWPARAMS* registers for ease accessing by
the driver.
