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

2011-10-04T17:25:55+00:00

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

usb: dwc3: gadget: implement streams support

2011-10-04T17:25:54+00:00

The following patch adds support for streams
to dwc3 driver.

While at that, also fix one small issue on
endpoint disable where we should clear all
flags not only ENABLED.

usb: dwc3: gadget: add support for Bursts

2011-10-04T17:25:54+00:00

We already have the value from gadget drivers,
just need to pass it to our controller.
