STM32F407: Each stream is connected to dedicated hardware DMA requests,…

Dear Community,

I want to know (for STM32F407) which DMA streams I can connect to peripheral hardware. From example-codes I know for example that SPI2 interconnects to DMA1_Stream4. The datasheet states: “Each stream is connected to dedicated hardware DMA requests,…” Nice to know that  connections are only working with “dedicated hardware” however the important information “which” stream connects to which hardware is missing. If someone knows the page of the datasheet or the reference containing a table or matrix showing the available connections between dma and peripheral hardware I would be glad if he/she would post the page number here.
