IAR generates warning Pe111 'statement is unreachable'. In a couple of
cases, replace return statements with TU_ATTR_FALLTHROUGH; because some
compilers apparently can't figure out that the return statements are
unreachable but do whinge about an imagined fall-through without them!
Some compilers don't support the GNU extension `typeof` so their definitions
of `hw_set_alias` can't inherit their type from their argument, and the best
we can do is have `hw_set_alias` act the same as `hw_set_alias_untyped`.
This requires an explicit cast when the macro is used instead, otherwise
IAR generates error Pe132 'expression must have pointer-to-struct-or-union
type but it has type "void *"'.
The same goes for `hw_clear_alias`.
- Stall now has priority over other interrupt responses
- Delete eunused hcd_edpt_busy
- Assert !ep->active when trying to start a new xfer
- Assert !ep->active when handling buff_status bits
- Set ep->xferred_len to 8 once a setup packet is finished so the data
structure is accurate
* Removed some compiler warnings, and cleaned out unnecessary warning suppression from CMake suppress_tinyusb_warnings()
* Made explicit family_configure_dual_usb_example() for DUAL mode examples as family_configure_target() may not generally be called multiple times for the same target
* Renamed library pico_pio_usb to tinyusb_picio_pio_usb to be clearer and avoid conflict if someone already has a pico_pio_usb in their project
* Added family_add_pico_pio_usb() method for adding Pico-PIO_SUB support to an existing example
* Allowed tinyusb_pico_pio_usb to be added to regular apps using the Pico SDK
