usbd: split bus reset into start/end edge events

2026-08-18T13:51:21Z

A driver that can see reset signalling begin has no way to say so: the only event carries the negotiated speed, which does not exist until the reset ends. On ChipIdea that left the stack believing it was still configured for the whole reset window - 3 ms at minimum, tens of milliseconds in practice - while the controller had already torn its endpoints down, so a class driver writing in that window primed a disabled endpoint over a zeroed queue head. Add DCD_EVENT_BUS_RESET_START for the leading edge and rename the existing event to DCD_EVENT_BUS_RESET_END, keeping DCD_EVENT_BUS_RESET as an alias. START is optional and END stays self-sufficient, so every other driver and the unit tests are untouched.

license: use SPDX identifiers for src/ headers (#3749)

* 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.

fix(device): big-endian host support for SETUP packet handling

2026-04-13T00:56:36Z

1. Add TU_LITTLE_ENDIAN_BITFIELD / TU_BIG_ENDIAN_BITFIELD macros in tusb_compiler.h (GCC and IAR), following Linux kernel style. 2. Update bmAttributes (tusb_desc_endpoint_t) and bmRequestType_bit (tusb_control_request_t) in tusb_types.h to use these macros with explicit #error fallback if undefined. 3. Add tu_le16toh() conversion in dcd_event_setup_received() for wValue/wIndex/wLength. Tested on CIU98320B (big-endian ARM Cortex-M, full-speed HID keyboard).

make TUP_DCD_EDPT_ISO_ALLOC i.e dcd_edpt_iso_alloc()/dcd_edpt_iso_activate() as default driver implementation. dcd_edpt_close() is deprecated and will be removed from all driver in the future.
