stm32 fsdev

• Add STM32L5 support
• Implement dcd_edpt_iso_alloc() and dcd_edpt_iso_activate()

OHCI

• Allows configurable root hub ports, handles SMM mode (Ref OHCI spec 5.1.1.3.3) and Bios mode (Ref OHCI spec 5.1.1.3.4)
• Fix FrameIntervalToggle must be toggled after we write the FrameInterval (Ref OHCI Spec 7.3.1)
• Wait PowerOnToPowerGoodTime after we enable power of the RH ports (Ref OHCI Spec 7.4.1)
• Generate port interrupts for devices already connected during init.
• Fix issue when removing queue head
• Disable MIE during IRQ processing and clear HccaDoneHead on completion as per OCHI Spec Page 80

Device Stack

• Add optional hooks tud_event_hook_cb()

Audio (UAC2)

• Fix feedback EP buffer alignment.
• Fix encoding, update example
• Improve IN transfer

Bluetooth

• Add historical EP compatibility for Bluetooth HCI

CDC

• Fix line_coding alignment
• Fix typo in cdc line coding enum

MIDI

• Fix stream_write() always writes system messages to cable 0
• Fix incorrect NOTE_ON, NOTE_OFF definitions

USBTMC

• Fix tmc488 bit order

Vendor

• fix read()/write() race condition

Video (UVC)

• Add the capability for video class to handle a bulk endpoint in the streaming interface.

Host Stack

USBH

• Add new APIs: tuh_interface_set(), tuh_task_event_ready(), tuh_edpt_abort_xfer(), tuh_rhport_reset_bus(), tuh_rhport_is_active()
• Fix issue when device generate multiple attach/detach/attach when plugging in
• Prefer application callback over built-in driver on transfer complete event
• Correct hcd_edpt_clear_stall() API signature
• Separate bus reset delay and contact debouncing delay in enumeration
• Support usbh_app_driver_get_cb() for application drivers
• Fix usbh enumeration removal race condition
• Add optional hooks tuh_event_hook_cb()

CDC

• Breaking: change tuh_cdc_itf_get_info() to use tuh_itf_info_t instead of tuh_cdc_info_t
• Fix cdc host enumeration issue when device does not support line request
• Add support for vendor usb2uart serial: ftdi, cp210x, ch9102f
• Improve sync control API e.g tuh_cdc_set_control_line_state(), tuh_cdc_set_line_coding()

HID
