If ci_hdrc_host_init() or ci_hdrc_gadget_init() returns error and the
error != -ENXIO, as Peter pointed out, "it stands for initialization
for host or gadget has failed", so we'd better return failure rather
continue.
And before destroying the otg, i.e ci_hdrc_otg_destroy(ci), we should

Currently, default vary will not accomodate superspeed endpoints
causing unexpected babble errors in the IN direction. Let's update
default 'vary' parameter so that we can maintain a "short-less"
transfer as hinted at the comment.

Make sure to deregister the USB driver before releasing the tty driver
to avoid use-after-free in the USB disconnect callback where the tty
devices are deregistered.

The PN_INT_ENA register should be used after usb3_pn_change() is called.
So, this patch moves the access from renesas_usb3_stop_controller() to
usb3_disable_pipe_n().

This patch fixes an issue that this driver is possible to cause
deadlock by double-spinclocked in renesas_usb3_stop_controller().
So, this patch removes spinlock API calling in renesas_usb3_stop().
(In other words, the previous code had a redundant lock.)

The USB3.0 peripheral controller on R-Car SoCs has a dedicated DMAC.
The DMAC needs a "PRD table" in system memory and the DMAC can have

This patch fixes an issue that this driver is possible to access
the registers before pm_runtime_get_sync() if a gadget driver is
installed first. After that, oops happens on R-Car Gen3 environment.
To avoid it, this patch changes the pm_runtime call timing from
probe/remove to udc_start/udc_stop.
This patch set is based on the latest Feribe's usb.git / testing/next branch
(the commit id = 28ea6be01e2cf244c461a40c8e9593816f894412.)
This patch set has 2 things:
- Fixes some minor issues.
- Add support for dedicated DMAC.
If possible, I want the patches [1/5] to [4/5] to be applied to v4.1
This controller disallows to change the PIPE until reading/writing
a packet finishes. However. the previous code is not enough to hold
the lock in some functions. So, this patch fixes it.

If the netdev is accessed before the urbs are initialized,
there will be NULL pointer dereferences. That is avoided by
registering it when it is fully initialized.
This case occurs e.g. if dhcpcd is running in the background

This driver implements the USB Type-C Power Delivery state machine
for both source and sink ports. Alternate mode support is not
fully implemented.
The driver attaches to the USB Type-C class code implemented in
