In order to add bcm6348-enet support, dma-uclass must be extended to support dma channels and reworked to operate like the other dm uclass (clk, reset...).

Thank you for picking this up. I, unfortunately, will be out unresponsive next few month due to personal reasons, but hope this will be moved forward eventually.

v9: Separate generic dma channels support from bmips enet support v8: Sync with latest u-boot. v7: From Grygorii Strashko:
- copyright fixed as suggested by Tom Rini
- added "Reviewed-by" tags
v6: From Grygorii Strashko:
- added possibility to pass DMA driver/channel's specific data per each
transfer using additional parameter "metadata" in dma_send/dma_receive() API. For example, port number for network packets to be directed to the specific port on multi port ethernet controllers.
- added new dma_prepare_rcv_buf() API which allows to implement zero-copy
DEV_TO_MEM transfer using DMA streaming channels which is usual case for Networking.
- added dma-uclass test
- removed unused function dma_get_by_index_platdata()
- updated comments
v5: Fix build of ti-edma3. v4: No changes v3: Introduce changes reported by Simon Glass:
- Improve dma-uclass.h documentation.
- Switch to live tree API.
v2: Introduce changes reported by Vignesh:
- Respect current dma implementation.
- Let dma_memcpy find a compatible dma device.
Grygorii Strashko (1): test: dma: add dma-uclass test
Álvaro Fernández Rojas (2): dma: move dma_ops to dma-uclass.h dma: add channels support
