mcb: move to_mcb_device() to use container_of_const()

2023-01-27T12:45:49+00:00

The driver core is changing to pass some pointers as const, so move
to_mcb_device() to use container_of_const() to handle this change.

to_mcb_device() now properly keeps the const-ness of the pointer passed
into it, while as before it could be lost.

mcb: Add a dma_device to mcb_device

2016-09-27T10:33:47+00:00

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.

mcb: remove sub-device handling code

2016-08-31T11:16:24+00:00

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.

mcb: Introduce type safety for to_mcb_*

2016-08-31T11:16:24+00:00

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

The mcb bus' device member wasn't correctly initialized and thus wasn't placed
