UAC2: Add more terminal types

2026-08-18T13:37:37Z

This adds more standard terminal types that can be used in descriptors to improve end user experience when operating system can present more acurate image for audio device terminal. Signed-off-by: Jerzy Kasenberg

audio_device: enforce the documented FIFO minimum in the EP-IN flow-control guard

2026-08-04T19:09:20Z

The comment above audiod_tx_packet_size() states flow control needs a FIFO of at least 4*Navg, but the guard tests nominal_size[1] <= fifo_depth * 4 - true for any FIFO larger than a quarter packet - instead of nominal_size[1] * 4 <= fifo_depth. As written, flow control engages on FIFOs far below its own documented minimum, where the depth/2 setpoint sits within one packet of empty and the packet_size = 0 branch (a zero-length packet, i.e. an audible 1 ms dropout for audio-class hosts) is reachable from ordinary scheduling jitter rather than only from gross clock deviation. With the guard corrected, undersized FIFOs fall back to the plain min(count, max) path as intended.

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

2026-07-02T14:55:45Z

* 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.

class/audio: remove unused audio20_control_request_t

2026-06-18T09:36:05Z

After the UAC2 examples switched to tusb_control_request_t with TU_U16_HIGH/LOW() extraction, audio20_control_request_t is no longer referenced anywhere in the tree. It is a byte-overlay of the setup packet whose bChannelNumber/bControlSelector/bInterface/bEntityID sub-byte fields silently misread on big-endian once wValue/wIndex are converted to host order (tu_le16toh in dcd.h), so leaving it in the public header is a latent BE trap; the BE bitfield guard previously added to its bmRequestType_bit only masked that by guarding byte 0. Drop the struct entirely. Callers should use tusb_control_request_t and TU_U16_LOW/HIGH(wValue|wIndex), matching audio_device.c and the examples. Co-Authored-By: Claude Opus 4.8 (1M context)
