USB: Revert "cdc-wdm: fix "out-of-sync" due to missing notifications"
This reverts commit
833415a3e781 ("cdc-wdm: fix "out-of-sync" due to
missing notifications")
There have been several reports of wdm_read returning unexpected EIO
errors with QMI devices using the qmi_wwan driver. The reporters
confirm that reverting prevents these errors. I have been unable to
reproduce the bug myself, and have no explanation to offer either. But
reverting is the safe choice here, given that the commit was an
attempt to work around a firmware problem. Living with a firmware
problem is still better than adding driver bugs.

USB-serial updates for v4.12-rc1
Here are the USB-serial updates for 4.12, including:
- support for devices with up to 16 ports (e.g. some Moxa devices)
- support for endpoint sanity checks in core, which allows for code sharing
and avoids allocating resources for rejected interfaces
- support for endpoint-port remapping, which allows some driver hacks to
be removed as well as omninet to use the generic write implementation
- removal of an obsolete tty open-race workaround which prevented a
port from being opened immediately after having been registered
- generic-driver support for interfaces with just a bulk-in endpoint
- improved ftdi_sio event-char and latency-timer handling
- improved ftdi_sio support for some broken BM chips
Included are also various clean ups and a new ftdi_sio device id.
All have been in linux-next with no reported issues.

usb: gadget: f_fs: simplify ffs_dev name handling
Currently ffs_dev::name can be either allocated by the client of
the ffs_dev structure or by the f_fs.c core itself. The former
is used by g_ffs while the latter happens with configfs.
Historically, g_ffs did not need to allocate separate buffer for
the name so what is now f_fs.c core never cared about freeing
that space. With configfs the name needs to be copied since the
memory is not guaranteed to be availeble after ffs_set_inst_name
finishes.
The complication is therefore here to avoid allocations in the
g_ffs case but it complicates the code inproportinally to
benefits it provides. In particular, g_ffs is considered
‘legacy’ so optimising for its sake is unlikely to be worth the
effort.
With that observation in mind, simplify the code by unifying the
code paths in g_ffs and configfs paths. Furthermore, instead of
allocating a new buffer for the name, simply embed it in the
ffs_dev structure. This further makes the memory management
less convoluted and error-prone.
The configfs interface for functionfs imposed a limit of 40
characters for the name so this results in a 41-byte buffer
added to the structure. (For short names this may lead to
wasted memory but the actual amount is not immediately obvious
and depends on pointer size and which slab buckets the structure
and name would fall into).

endpoints, including OUT and IN endpoint 0.
- DWC_USB3_NUM_IN_EPS indicates the maximum number of Device mode IN
endpoints active at any time, including control endpoint 0.
It's possible to configure RTL such that DWC_USB3_NUM_EPS is equal to
DWC_USB3_NUM_IN_EPS.
dwc3-core calculates the number of OUT endpoints as DWC_USB3_NUM minus
DWC_USB3_NUM_IN_EPS. If RTL has been configured with DWC_USB3_NUM_IN_EPS
equal to DWC_USB3_NUM then dwc3-core will calculate the number of OUT
endpoints as zero.
For example a from dwc3_core_num_eps() shows:
[ 1.565000] /usb0@
f01d0000: found 8 IN and 0 OUT endpoints
This patch refactors the endpoint calculation down to one variable
dwc->num_eps taking care to maintain the current mapping of endpoints for
fixed FPGA configurations as described in Table 4-7 of version 2.60a of the
DWC USB3 databook.
The endpoint mapping will then be EP-OUT, EP-IN etc, up to DWC_USB3_NUM.

usb: dwc2: Make sure we disconnect the gadget state

that I finally seemed to have chased down. Basically every other
time I plugged in the OTG port, the gadget interface would
properly initialize. The other times, I'd get a big WARN_ON
in dwc2_hsotg_init_fifo() about the fifo_map not being clear.
Ends up if we don't disconnect the gadget state, the fifo-map
doesn't get cleared properly, which causes WARN_ON messages and
also results in the device not properly being setup as a gadget
every other time the OTG port is connected.
So this patch adds a call to dwc2_hsotg_disconnect() in the
reset path so the state is properly cleared.
With it, the gadget interface initializes properly on every
plug in.

phy: phy-mt65xx-usb3: split SuperSpeed port into two ones
Currently usb3 port in fact includes two sub-ports, but it is not
flexible for some cases, such as following one:
usb3 port0 includes u2port0 and u3port0;
usb2 port0 includes u2port1;
If wants to support only HS, we can use u2port0 or u2port1, when
select u2port0, u3port0 is not needed;
If wants to support SS, we can compound u2port0 and u3port0,
or u2port1 and u3port0, if select latter one, u2port0 is not needed.
So it's more flexible to split usb3 port into two ones and also try
best to save power by disabling unnecessary ports.
