* 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(host): release spinlock in tuh_deinit to fix multi-rebuild panic

2026-06-21T09:46:26Z

tuh_rhport_init() calls osal_spin_init(&_usbh_spin), which under OPT_OS_PICO claims a hardware spinlock via critical_section_init(). There was no osal_spin_deinit(), so tuh_deinit() never released it: every host init/deinit cycle leaked one spinlock. RP2350 has a small spinlock pool, so a few usb_host rebuilds exhaust it and hw_claim_unused_from_range() panics (the long-standing "crashes on the 4th rebuild" bug). Add osal_spin_deinit() to all OSAL backends (critical_section_deinit for pico; no-op for none/freertos) and call it in tuh_deinit(). Verified 20/20 deinit+rebuild cycles on RP2350-Zero and Waveshare RP2350-USB-A (previously panicked on the 4th). Co-Authored-By: Claude Opus 4.8 (1M context)
