* license: use SPDX identifiers for src/ headers
Replace the full ~20-line MIT license boilerplate on every src/ file with a
two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following
the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500
lines of duplicated boilerplate.

TUSB_OPT_DEVICE_ENABLED still usable for backward compatible
|
|
Going to suspend states disable reception on non-0 RX endpoints.
Now when USB resume condition is detected, all RX endpoints
with pending transfers are resumed.
|
|
Bit mask enabling/disabling over-run/unde-run was shifted
by one nibble, so interrupt was never enabled.
It did not force any issue as this situation could only
happen on ISO endpoints without DMA.

since gcc does difference between volatile struct and member when
casting pointer
|
|
USB3CV tool verifies MSC device by sending too short or
too long packets.
In case of too long packets (msc_device requested 31 bytes
but incoming data had 32 bytes) extra byte(s) were left in
FIFO resulting in some data mismatch later on.
Now if more data is received in packet that expected extra
bytes are just dropped.

Normal TX handler for IN non-0 endpoints is called during
outgoing transfer or just after it was finished.
It may need to fill TX fifo with same data if TX_DONE is present
but ACK_STAT is not.
It may need to fill more data when called during transfer.
But it may also be called when STALL was sent.
In this case TX_DONE is set ACK_STAT is not, just like for packets
that were sent but no ACK was received.
Code was trying to send something again. There was nothing to send
so empty ZLP was scheduled for stalled endpoint.
This ZLP was later send to host where valid response was required.
This change checks if notification was for STALL endpoint and
does not try to fill TX FIFO in that case.

da146xx bus reset and sleep reworked

dcd_da146xx: Remove registers pointer from xfer_ctl_t
|
|
Unconditionally disables all endpoints except EP0.
|
|
Closing endpoint clears data in affected xfer_ctl_t
|
|
Note: this commit does not change any logic.
xfer_ctl_t structure keeps all dynamic data connected with transfer.
It used to have pointer to register set that was constant and was there
for convenience only.
Removing register pointer from structure makes cleanup easier as whole
structure can be erased with memset like function.
In many cases functions were using local variable regs and xfer->regs which
were same, that could be confusing so this part is unified.
Few macros were added for easy conversion between epnum, xfer, and regs.
|

So far bus reset was handled (with some holes in it).
Sleep and remote wakeup were not really tested and did not work.
With this change:
- bus reset is reworked
- remote wakeup works
- bus signal sleep is handled
|
|
Not much of an improvement but handle only interrupts
that were enabled and are expected.

DA146xx are Bluetooth devices that may be battery
powered and when not connected to USB host there
is no need for USB peripheral to be running.
This change allows to enable USB peripheral when
VBUS is present otherwise USB is down reducing
power consumption.
tud_vsub_changed() function must be called
whenever VBUS change was detected.
For bus-powered devices this function should be called
at startup since VBUS must be present while device
is working.

correctly responded to TD 9.13 Set Configuration Test
|
|
For self powered device if device started without VBUS present
it would not be correctly attached to USB bus even if tusb_vbus_changed()
was later called.
This modifies dcd_init() so it starts USB state machine without checking
if VBUS is present or not, like all others drivers do.
tusb_vbus_changed() function is also removed its content was moved to dcd_init.

dcd_da1469x can work with broader range of MCUs that
share same USB core.
Specific header file that was used DA1469xAB.h now it is changed
to mcu/mcu.h which includes actual MCU specific register file.

FIFO is limited to 64 bytes yet MCU is capable of transmitting
larger packets provided that FIFO will be filled on the fly
and USB_USB_TXCx_REG_USB_LAST_Msk bit is set after FIFO is
filled with all the data that should be transmitted.
This change allows to use FIFO level warning interrupt to fill
FIFO. When DMA is available it will be used instead of interrupts.
Some function names were changed to better reflect what each function
does.
|
|
Few changes were needed to have working ISO endpoints.
|
|
Closing endpoints can be important when there are alternate
instances. This adds functionality of closing endpoints
similar to what exists in other drivers.
|
|
Internal FIFO for each endpoint is limited to 64 bytes.
It is possible to have longer packets if respective FIFO
is read during actual packet transmission.
This change updates receive data path to allow packets (and
endpoint size) larger then 64 bytes.
If DMA is not used yet DMA is setup for reception of big packets.
If DMA is already assigned to some transfer, code enables FIFO level
warning interrupts and tries to read data before FIFO is filled up.

Dialog Semiconductor's BLE MCU DA1469x comes with full speed USB.
It's base on National Semiconductor discrete USB controller USBN9603/4.
This adds support for:
- control/interrupt/bulk endpoints (up to 64 bytes)
- ISO endpoint were not tested and may not work correctly
- reset/sleep/wakeup are handled
- code for VBUS changes is provided
