Version-header source: same tag cores/esp32/esp_arduino_version.h.
Both files preserve their upstream copyright and Apache-2.0 notices.
The full source is necessary to verify the exact input fingerprint and all
producer/ISR/reset replacement sites without a PlatformIO package dependency.
Underlying correction: upstream commit2ecad233178bfbba9c584ffd9f67e941d84adbb7,

usb_phy_ll.h is the exact upstream ESP-IDF v4.4.7 ESP32-S3 HAL header:

It preserves its upstream copyright and Apache-2.0 notice. The executed
HWCDC::begin regression uses these official HAL bodies to test retained RTC
PHY ownership after a TinyUSB-to-HWCDC software restart, including a host
disconnect before the controller changes. It does not simulate enumeration.
