Add USB Video Class 1.1 gadget driver supporting Bulk transport with uncompressed YUY2 video streaming. Resolution and frame interval are negotiated dynamically via PROBE/COMMIT control. - uvc.h: protocol constants, streaming control struct, public API - uvc.c: class driver with PROBE/COMMIT, bulk EP, /dev/uvc0 chardev - Kconfig/Make.defs: USBUVC config and build rules - boardctl.c: BOARDIOC_USBDEV_UVC standalone init path Hardened against host disconnect: - Removed nxmutex_lock from USB interrupt context paths - Added 30s semaphore timeout in uvc_write with EP_CANCEL fallback - Drain stale wrsem counts in VS_COMMIT before new stream - Guard uvc_streaming_stop() against double EP_CANCEL race - Handle EP_SUBMIT returning -ESHUTDOWN gracefully Signed-off-by: wangjianyu3 <wangjianyu3@xiaomi.com> |
