- examples/device/midi2_device/src/main.c: drop the unreachable
`return 0;` after the `while(1)` superloop. IAR with
--warnings_are_errors rejects Pe111 (statement is unreachable);
C99 lets `int main` fall off the end, matching midi_test.
- examples/host/msc_file_explorer_freertos/skip.txt: skip
stm32h7s3nucleo. The board has only 64 KB on-chip FLASH and the
FreeRTOS + FatFS host MSC explorer now overflows by ~248 bytes
after the async control queue refactor.

iccarm rejects -Wno-type-limits, breaking the hil-hfp-iar CI matrix
(stm32l412nucleo, stm32f746disco, lpcxpresso43s67). Apply the same
CMAKE_C_COMPILER_ID guard used in hw/bsp/family_support.cmake so IAR
builds skip the flag without losing the GCC warning suppression.

To avoid STATUS IN completion of previous control transfer treated as next DATA IN when IRQ latency is high.

Handle OUT transfer differently from IN to not prematurely change MTP phase when host sends short packet that is not end of MTP data phase. Only reaching container length or ZLP should change phase.

- Added a pending FIFO queue for asynchronous control transfers when the active slot is busy.
- Introduced `control_xfer_dispatch_pending` to handle queued transfers on slot availability.
- Improved synchronization for blocking and non-blocking transfer modes, preventing deadlocks in RTOS.
- Refactored and renamed related functions for clarity and consistency.
- Enhanced error handling and callback invocation for failed or stale transfers.

- GRXSTSP register has internal FIFO, receiving events won't mix up (STATUS OUT & next SETUP)
- Improve efficiency, remove 2nd IRQ overhead

According to WCH FAE transfer complete interrupt is not queued, later completed EP will overwrite INT_ST and RX_LEN.
Which means to guarantee data integrity when multiples EPs are enabled:
- USB IRQ must have highest priority
- IRQ processing time must be less than ZLP duration (~600ns), which is absurd for a 144MHz CPU (85 cycles)

- Removed `pyfatfs` dependency in favor of `mtools` for reading FAT volumes, simplifying the block device read logic.
- Updated `requirements.txt` and added detailed host setup instructions for system packages.
- Switched to `cython-hidapi` for HID tests, replacing deprecated APIs with updated usage.
- Removed unnecessary warnings suppression and `fs` module.

ch32_usbhs: fix endpoint stall length index and clear-stall response
|
|
|
|
|
|
|
|
Fix issue in the stall handling:
- dcd_edpt_stall() for an IN endpoint cleared EP_TX_LEN(0) instead of
EP_TX_LEN(ep_num), clobbering endpoint 0's transmit length register
when stalling any other IN endpoint.

Track EP0 control transfer state from SETUP (direction and wLength) and gate CH32 EP0 handshakes accordingly. Switch EP0 type away from control to bulk to block unsolicited OUT ACKs during control read/write gaps, then restore control type when EP0 transfer is explicitly armed.

fix(dcd_ch32_usbfs): fix dropped bulk OUT packets by properly re-arming EP_RX_CTRL state

Refactor the driver to follow USBFS style for easier maintenance.
Replace the old packet/response helpers with explicit queue and update paths for IN and OUT transfers.
Introduce transfer validity tracking and per-endpoint data toggle state.
Reset toggle state on init, close-all, endpoint close, clear-stall, and bus reset.
Initialize endpoint controls consistently in NAK + TOG_0 mode.
Tighten EP0 setup/status handling and route transfer IRQ processing through the transfer-flag path.
Stop enabling ISO_ACT in INT_EN and clear unhandled interrupt flags explicitly.
