* 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.

feat(midi2): derive function blocks from the GTB descriptor

2026-06-28T19:28:29Z

Function Block Info (direction, group span, name) is derived from the GTB descriptor as the single source of truth, so a device can expose multiple Group Terminal Blocks with independent directions. Adds Function Block Name notifications (tud_midi2_fb_name_cb) and an opt-in callback to answer UMP Stream messages from the application (tud_midi2_stream_msg_cb). Ref #3571

midi2: boundary-aware drain in xfer_cb to keep UMP packets intact

midi2: per-interface weak callbacks for UMP Stream config

2026-05-17T15:19:45Z

Lets each instance return different NUM_GROUPS, NUM_FUNCTION_BLOCKS, EP_NAME and PRODUCT_ID. Defaults fall back to the macros.

midi2: peek 4 bytes for MT, restore 256 buffers

2026-05-17T14:31:12Z

MT is in byte 3 of the UMP word in LE memory, not byte 0. Buffers at mps blocked RX xfer re-arm on partial packets.

midi2: prevent UMP packet split across USB transfers

2026-05-16T15:59:44Z

The edpt_stream auto-flush is byte-oriented and could cut an UMP message in half when the FIFO reached wMaxPacketSize, corrupting the peer's RX context. Pre-flush whole packets before writing one that would cross the boundary on both device (tud_midi2_n_ump_write) and host (tuh_midi2_ump_write) paths. Host write also becomes packet-aware instead of word-by-word. Ref #3571
