• 2d8784df1   mcb: Add a dma_device to mcb_device ... Browse Code »

  When performing DMA operations on a MCB device, the device needed
  for using the DMA API is "mcb_device->bus_carrier".
  This is rather lengthy, so a shortcut is introduced to struct mcb_device
  in order to ensure the MCB device driver uses the correct device for DMA
  operations.

• b58189b3c   mcb: remove sub-device handling code ... Browse Code »

  The MEN Chameleon specification states that a chameleon FPGA can include a
  bridge descriptor, which then opens up a new bus behind this bridge. MCB
  included subdevice handling code in the core, but no support for bus
  descriptors in the parser, due to a lack of hardware access.

  As this is technically dead code, but it gets executed on a device add,
  I've decided to remove it.

  The to_mcb_{bus,device,driver}() macros lacked type safety, so convert them to
  inline functions to enforce compile time type checking.

  Export information about the bus stored in the FPGA's header to userspace via
  sysfs, instead of hiding it in pr_debug()s from everyone.

  The mcb bus' device member wasn't correctly initialized and thus wasn't placed
  correctly into the driver model.

  The MCB (MEN Chameleon Bus) is a Bus specific to MEN Mikroelektronik
  FPGA based devices. It is used to identify MCB based IP-Cores within
  an FPGA and provide the necessary framework for instantiating drivers
  for these devices.
