Add debugobject support to track the life time of struct urb.
This feature help us detect violation of urb operations by
generating a warning message from debugobject core. And we fix
the possible issues at runtime to avoid oops if we can.
I have done some tests with some cl

The musb driver can drop rx packets when heavily loaded. These two
patches address two issues that can cause this. Both issues arose
when an endpoint was reprogrammed. The first patch is a logic bug
that resulted in a shared_fifo in rx mode not having its state
cleared out. The second patch fixes a
shared_fifo endpoints would only get a previous tx state cleared
out, the rx state was only cleared for non shared_fifo endpoints
Change this so that the rx state is cleared for all endpoints.
This addresses an issue that resulted in rx packets being dropped
silently.

Ensure that the endpoint is stopped by clearing REQPKT before
clearing DATAERR_NAKTIMEOUT before rotating the queue on the
dedicated bulk endpoint.
This addresses an issue where a race could result in the endpoint
receiving data before it was reprogrammed resulting in a warning
about such data from

It's OK. Get me a big patch fixing it all when you're combed through
things and we can apply it for fixes/stable.

Hi Felipe, Laurent,
I submitted this driver for a Cadence IP library from a now abandoned project.
The driver was working on a SoC platform ported on a FPGA, but I do not have
access to this HW anymore.
But I have a fixed version...
Now, I am looking for SoCs, vendors and even Cadence people (

dwc3-exynos has two problems during init if the regulators are slow
to come up (for instance if the I2C bus driver is not on the initramfs)
and return probe deferral. First, every time this happens, the driver
leaks the USB phys created; they need to be deallocated on error.
Second, since the phy
