      ks8842: Support DMA when accessed via timberdale · 94fe8c68
      Richard Röjfors authored
      This patch adds support for RX and TX DMA via the DMA API,
      this is only supported when the KS8842 is accessed via timberdale.
      
      There is no support for DMA on the generic bus interface it self,
      a state machine inside the FPGA is handling RX and TX transfers to/from
      buffers in the FPGA. The host CPU can do DMA to and from these buffers.
      
      The FPGA has to handle the RX interrupts, so these must be enabled in
      the ks8842 but not in the FPGA. The driver must not disable the RX interrupt
      that would mean that the data transfers into the FPGA buffers would stop.
      
      The host shall not enable TX interrupts since TX is handled by the FPGA,
      the host is notified by DMA callbacks when transfers are finished.
      
      Which DMA channels to use are added as parameters in the platform data struct.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
