Hi,
Now that we can use the build-in properties as fallback when the
primary firmware (DT or ACPI) does not provide the requested property,
it should be always safe to add them. I.e, by adding them to a device,
nothing will be overwritten.
Changes since v1:
- s/taps/tapes/ in dwc3-pci.c
- Dropped

Some devices I got show an inability to operate right after
power on if they are already connected. They are beyond recovery
if the descriptors are requested multiple times. So in case of
a timeout we rather bail early and reset again.
This patch is a rework of a patch that fell through the cracks
According to DWC2 documentation, DPTxFSize field of DPTXFSIZn register
is read only, which means that software cannot change FIFO size.
Register description says:
"The value of this register is the Largest Device Mode Periodic Tx Data

Since we handle FIFOs and endpoint separately, using variable named 'ep'
in context of FIFO is misleading, hence we rename it to 'fifo'.

Since FIFO is always freed in dwc2_hsotg_ep_disable(), ep->fifo_index
is always 0 in dwc2_hsotg_ep_enable(), hence code inside if() block is
never executed.

Hello,
This patch series fixes TX FIFO handling in UDC part of DWC2 driver.
It gets rid of few bugs, improves compliance with DWC2 documentation
and cleanes up driver code. More detailed description is provided in
commit messages.
Best regards,
Robert Baldyga
Changelog:
v2:
- Addressed comments
USB requests in SourceSink function are allocated in sourcesink_get_alt()
function, so we prefer to free them rather in sourcesink_disable() than
in source_sink_complete() when request is completed with error. It provides
better symetry in resource management and improves code readability.

Add a new interface for userspace to preallocate memory that can be
used with usbfs. This gives two primary benefits:
- Zerocopy; data no longer needs to be copied between the userspace
and the kernel, but can instead be read directly by the driver from
userspace's buffers. This works for a

The phy-am335x driver selects 'USB_COMMON', but all other drivers
use 'depends on' for that symbol, and it depends on USB || USB_GADGET

warning: (AM335X_PHY_USB) selects USB_COMMON which has unmet direct
dependencies (USB_SUPPORT && (USB || USB_GADGET))
