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...).
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.
