bsp(ch32): naked fsdev ISRs so nested USBD IRQs return safely

2026-07-09T16:38:48Z

The three USBD lines nest under QingKe HWSTK; gcc's interrupt prologue corrupts the return, so rely on the hardware stack and bare mret. Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

replace board_millis() with tusb_time_millis_api()

always define CFG_TUH_WCH_USBIP_USBFS=1 for ch32v20x since only port1 support host mode

Allow different port and mode for LED on ch32v boards

2025-04-06T15:14:32Z

While there is a define for the port, the clock enable is hardcoded for GPIOA, so setting a different port than GPIOA doesn't work. This fixes it by adding a define for enabling the port clock. It also adds a define for the pin mode, because not all boards have the LED connected in a way that open drain works with it.

Fix the condition related to CFG_TUH_WCH_USBIP_USBFS macro

Add ch32v20x usbfs hcd initial support.
