This commit is a draft to support more controller implementations
with these drivers. The goal is also to make it easier to port
this driver to the new UDC API later.
We use compatible, like st,stm24f4-fsotg to support and enable
vendor-specific quirk. The core of the driver remains generic,
and therefore described and enabled by snps,dwc2 compatible.
STM32F4 support requires PINCTRL, even though pinctrl API is
generic, not all platforms implement it, so we have to include
and compile it conditionally.
Now we also switch to use new snps,dwc2 compatible and
explicitly force the controller into device mode,
as we do not support other roles or role changes.

The MCUX USB device driver currently suffers from
some performance related issues caused by the removal
of the intermediate buffer in commit 4e6f80d37a.
This buffer was essential in the case when some USB
descriptors or data were in a slow access memory,
for example a flash memory accessed over flexspi.
USB DMA as AHB master would try to fetch the data,
but it would be too slow and USB peripheral
could not meet deadlines on the USB bus waiting for it,
and so it would send null packets instead causing errors.
This problem can be fixed by re-introducing an intermediate
buffer in RAM with the data copied from the slow memory by
the core before the USB transfer begins, so that USB DMA
is not responsible for fetching it from flexspi/flash.
Changes to MCUX USB Device Driver:
- Re-add intermediate buffer for USB writes in RAM
- Buffer is not needed for reads, add runtime check
to avoid copy overhead
- Buffer is not needed for platforms with USB RAM,
since the USB RAM itself acts as an intermediate buffer.
Compile with buffer code only when USB RAM is not present on
the platform, to avoid unecessary copy overhead.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the

Description of the bad behaviour before this change:
The arming of the control EP0_OUT endpoint was not kept under
control. It could happen that the EP0_OUT endpoint was left
armed, after the completion of a complete control transfer.
It is clear that the intention was to NOT keep EP0_OUT constantly
armed while idle, because usb_dc_ep_enable() doesn't arm it,
and the intention was for when usb_dc_ep_read() is called to
collect the Setup-Stage 8-byte data, that is when EP0_OUT is armed,
and before this call is performed, the host will keep getting NAKs
for the Data-Stage of the to_device control transfer.
This happens correctly on the first to_device control transfer with
wLength > 0. However, because usb_dc_ep_read_continue() indiscriminately
re-arms all OUT endpoints, in the case of to_device control transfers
with wLength > 0, on the Data-Stage, the endpoint is also re-armed,
which is wrong, because then the endpoint will be left armed after
the control transfer is over.
In this case when a new to_device control transfer starts, the
Data-Stage will be accepted on the first try. This would still
have worked without a failure if the Setup-Stage would have been
processed immediately, but because we process everything in a work
queue at a later time, when the Setup-Stage associated 8-byte data
buffer is read both the Setup-Stage and Data-Stage have arrived.
At the end of handling the Setup-Stage we try to re-arm the EP0_OUT,
which already contains data, thereby corrupting the received length
portion of the buf_ctl register. (Obviously other fields are changed
too, but the length field is the one that first causes chaos, cause
it's written to the maximum, which is 64.) The above mentioned Data-Stage
already has a message in its workqueue for it to be processed, but
it is picked up only after the length field has been corrupted.
Because of this usb_dc_ep_read() thinks there is more data in the buffer
than there really is, and everything becomes de-synchronized, with
later reads accessing uninitialized parts of the buffer.
This sounds like a fundamental failure, that should make it impossible
to operate USB, however the reason this behaviour doesn't make it
impossible to enumerate the device is that this only affects
to_device control transfers with wLength > 0, and during enumeration
there are not many of those happening.
When enumerating a HID keyboard, there is only _one_ of those
happening, and it is the initial setting of the lock light led status.
And that first one succeeds because it's the first one. (However, later
lock light setting control transfers can cause problems, which is how
this problem was encountered.)
The solution in this commit is to keep better control over when EP0_OUT
is armed. This forces the Data-Stage to arrive later (the host will keep
re-trying), and that way the corruption of the buffer control register
is avoided.
Summary of the changes:
- Rework the logic around deciding wether to re-arm the out endpoint
after a read. For non-0 endpoint the previous behaviour is kept,
however for EP0 it is only re-armed if more OUT transactions are
expected for that SETUP transfer (be it data-stage or status-stage)
- Force un-arm the EP0_OUT endpoint in case a stall condition is observed.
- When a setup transfer is received check if EP0_OUT is already armed.
If armed then log a warning message, and force-disarm it.
- When a setup req interrupt fires, don't immediately force the next
read to get it, instead, it will be read only after a setup message
is extracted from the message queue.
- When a setup packet is received abort any unfinished previous control
transfers:
- cancel any data buffers given to the EP0_IN endpoint
- drop any new ep0_in writes that are attempted before this newest
setup packet's associated message is extracted from the message
queue.
- In the ISR, check buffer interrupts before setup req interrupts.
This is to make sure that the final 0-length status message from the
previous setup packet is consumed before the new setup packet.
(this is the only case now when both interrupts could be seen as
having fired by the time the interrupt handler routine executes.

I believe this comment and condition may have found its way into the
rp2040 driver from other drivers where it makes more sense. For
example for the stm32 driver performing a read on the EP0_IN endpoint
turns it silently into a read on the EP0_OUT endpoint. As far as I can
tell, this really was only used to consume 0-length Status-Stages of
to_host control transfer in the other drivers.
Note that usb_dc_ep_start_read() is never called in an IN endpoint
in the rp2040 driver, and furthermore, even if it would have been
called like that, the current implementation would not do the silent
change into actually performing a read on the EP0_OUT endpoint instead,
so the condition and comment is just wrong.
Note that 0-length Status-Stage of to_host control transfers is
currently consumed in this driver by usb_dc_ep_read_continue().

The data stage of Control transfers that are sent from Host to Device, can
be made out of multiple OUT transactions, if the amount of data to be
transmitted is larger than the endpoint size. When this happens, the DATA
pid should be toggling. The USB Device driver of the pico must correctly
prime the EP0_OUT buffer with the correct data PID, otherwise the hardware
will reject the received transaction.
Before this change the driver used to always prime EP0_OUT with a DATA1
pid.
After this change the driver only uses DATA1 pid after a setup transaction,
and then toggles the pid for each transaction.

This driver enables a number of interrupts it does not attempt to handle.
This results in "unhandled IRQ: 0x...." messages being printed, and the
interrupt handler retriggers immediately again, and this happens again
and again forver, because nothing ends up clearing the interrupt.
This change implements very limited handling of these interrupts. A custom
warning is logged, and the interrupt is cleared.
This change does not imply that doing this is sufficient. More changes may
need to be implemented to more gracefully re-start transactions or
re-arm some endpoints, but this is one step in the right direction,
and at least the OS doesn't freeze up.

The usb_dc_sam0 driver is leaking memory when the usb device is detached
using usb_disable().
When a device is detached, the driver does not reliably deallocate the

another block of memory is allocated. After several connect /
disconnect sequences, the usb interface becomes unresponsive.
This commit adds a static function to release all memory allocated
to the ep descriptors when usb_dc_detach() is called. Since detach is
called from usb_disable(), this releases the memory when the
interface is disabled.

So far thread was created as part of usb_dc_attach() by k_thread_create().
This means that if following function were executed:
* usb_enable()
* usb_disable()
* usb_enable()
then k_thread_create() was called second time. This results in undefined
behavior.
Fix above issue by moving k_thread_create() invocation to function called
during system initialization.
While at it, move IRQ_CONNECT() and irq_enable() invocations to init as

Soft resetting a STM32 device currently does not reset the USB
connection, which causes a few problems: The endpoints do not respond
anymore, and within zephyr any kind of status information like
CDC_SET_CONTROL_LINE_STATE is also missing as they are not
re-negotiated.
This is fixed by stopping the USB device from zephyr side, right after
initialising the USB device.

On SoCs with two USB controller, Zephyr selects the FS one, and in that
case the ULPI clock needs to be disabled in sleep mode for the
controller to work.

The ULPI clock uses slightly different names on STM32H7X as those
SoC can have more than one USB controller.
Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
On STM32H7X SoCs, both USB controllers are HS capable, however it is not
possible to connect an ULPI PHY to the USB2 one, which limit it to FS.
Therefore the ULPI clock in sleep mode has to be disabled for USB2 in
all cases. The ULPI clock for USB1 is already disabled when needed in
the usb_dc_stm32_clock_enable() function like for other SoCs.

Do not manually enable the USB clock on STM32H7, as it is already done

For some reason, rather than testing for the presence of
disconnect-gpios in the devicetree, the STM32 USB Device driver was
relying on a hidden Kconfig flag to be set.
This patch removes the Kconfig option completely and simply tests for
the DT property - if it's set, you obviously know what you're doing and
obviously need the pull-up GPIO behaviour.

Fill in received bytes in USBIP_RET_SUBMIT packet
Currently this field is unconditionally set to 0 and therefore not
filled in conveniently. This may mislead the USB host which is correctly
acknowledged that the transaction was sucessful but it cannot check the
actual received bytes.
Test application:
```python
import usb
data = (0xFF, 0xFF)
print("Opening loopback device")
device = usb.core.find(idVendor=0x2FE3, idProduct=0x0009)
print("Writing test data", data)
written = device.write(0x1, data)
print("Written", written, "bytes")
```
Before:
```
$ ./test_loopback.py
Opening loopback device
Writing test data (255, 255)
Written 0 bytes
```
After:
```
$ ./test_loopback.py

The USB configuration option is actually a global switch
to enable USB drivers in general, but currently only
the device controller drivers are meant.
USB device controller drivers also have USB_DEVICE_DRIVER option.
Thus the option USB is actually redundant and can be replaced
by the self-explanatory option USB_DEVICE_DRIVER.
The name USB itself is not unique and should not be used as an
configuration option.
With these changes the option USB_DEVICE_DRIVER generally
enables USB device controller drivers. The option USB_DEVICE_STACK
enables USB device support. It is sufficient to enable only option
USB_DEVICE_STACK because it selects USB_DEVICE_DRIVER.
CONFIG_USB Kconfig option is temporary added to subsys/usb/Kconfig.
This is necessary to pass CI and will be removed again
when the USB configuration has been adapted in modules.
