There are 3 instances of HPDMA on stm32mp251, using stm32-dma3 driver, with 16 channels per instance and with one interrupt per channel. Channels 0 to 7 are implemented with a FIFO of 8 bytes. Channels 8 to 11 are implemented with a FIFO of 32 bytes. Channels 12 to 15 are implemented with a FIFO of 128 bytes. Thanks to stm32-dma3 bindings, the user can ask for a channel with specific FIFO size.
