Detailed Description

STM32 GPDMA 串口适配器 / STM32 GPDMA UART adapter.

持有四个线性接收节点与循环链表，数据缓冲区由调用者提供。 Owns four linear RX nodes and their circular list; the caller supplies the payload.

Precondition: UART、DMA 句柄及缓冲区在传输期间有效且由本后端独占；相关 UART/DMA 中断具有相同抢占优先级，运行中的 DMA 中断必须使能。 UART/DMA handles and buffers remain valid and exclusively owned by this backend. Related UART/DMA IRQs share a preemption priority; active DMA IRQs must be enabled.
