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...).
v11: Introduce change suggested by Daniel Schwierzeck: - Avoid trimming ethernet FCS from DMA driver. v10: Introduce changes suggested by Daniel Schwierzeck: - Fix license identifiers. bcm6348-iudma: - Move DMAD_ST defines out of dma desc struct definition. - Remove unneded aigned attribute from dma desc struct definition. - Fill dma ring from consumer driver instead of allocating a new buffer. - Correctly check clock/reset errors while probing. - Switch to live DM live tree. bcm6348-enet: - Remove packet queue. - Move dma_prepare_rcv_buf to free_pkt. - Switch to live DM live tree. bcm6368-enet: - Remove packet queue. - Move dma_prepare_rcv_buf to free_pkt. - Pad packets smaller than ETH_ZLEN. - Switch to live DM live tree. v9: Separate generic dma channels support from bmips enet support bcm6348-iudma: - bcm6348_iudma_chan_stop: switch to mdelay when resetting channel. - bcm6348_iudma_receive: track dirty dma descriptors and no longer trigger dma rx channel. - bcm6348_iudma_send: reorder to properly flush cache and set dma descriptor config. - bcm6348_iudma_prepare_rcv_buf: implemented to clear dirty dma descriptors. bcm6348-enet: - bcm6348_eth_recv: clear dirty dma descriptors only when packets are copied from rx dma. - bcm6348_eth_send: remove dma rx channel reset when sending packet. bcm6368-enet: - introduce rx packets caching functionality from bcm6348-eth to fix flow control issues. - code style fixes. v8: Introduce bcm6368-enet driver support. v5: Fix issues reported by Grygorii Strashko and other fixes: - Remove unused bcm6348-iudma defines. - Increment bcm6348-iudma rx descriptors. - Fix bcm6348-iudma flow control issues. - bcm6348-iudma error checking now depends on hw. - Remove unneeded bcm6348-iudma interrupts. - Receive as much packets as possible from bcm6348-eth and cache them in net_rx_packets. This is needed in order to fix flow control issues. v4: Fix issues reported by Grygorii Strashko and other fixes: - Remove usage of net_rx_packets as buffer from bcm6348-iudma. - Allocate dynamic rx buffer on bcm6348-iudma. - Copy received dma buffer to net_rx_packets in order to avoid possible dma overwrites. - Check dma errors and discard invalid packets. - Reset dma rx channel when sending a new packet to prevent flow control issues. - Fix packet casting on bcm6348_eth_recv/send. v3: Switch to live tree API. v2: Fix bcm6348-iudma rx burst config.
