mcb: introduce mcb_get_resource()

2017-08-28T18:51:22+00:00

Introduce mcb_get_resource() as a common accessor to a mcb device's memory or
IRQ resources.

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.

mcb: export bus information via sysfs

2016-05-03T22:07:35+00:00

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.

mcb: Correctly initialize the bus's device

2016-05-03T22:07:35+00:00

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

drivers: Introduce MEN Chameleon Bus

2014-02-28T23:36:37+00:00

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.
