5   STM32 DMA controller for the stm32U5 soc family
7   It is present on stm32U5 devices as a GP DMA
8   This controller includes several channels with different requests.
9   DMA clients connected to the STM32 DMA controller must use a three-cell
17      dma-names = "tx", "rx";
19   It is a phandle to the DMA controller plus the following three integer cells
20     1. channel: the stream or channel from 0 to (<dma-channels> - 1).
21     2. slot: DMA periph request ID, which is written in the REQSEL bits of the CxTR2
22     the slot is a value between <0> .. (<dma-requests> - 1).
23     3. channel-config: A 32bit mask specifying the DMA channel configuration
25         -bit 6-7 : Direction  (see dma.h)
30         -bit 9 : Peripheral Increment Address
33         -bit 10 : Memory Increment Address
36         -bit 11-12 : Peripheral data size
38                0x1: Half-word (16 bits)
41         -bit 13-14 : Memory data size
43                0x1: Half-word (16 bits)
46         -bit 15: Reserved
47         -bit 16-17 : Priority level
