Hello everyone, This is the third posting of these drivers, taking into account comments from earlier postings. The DMAEngine patches are in mainline now, and therefore are not part of this series anymore.
RFCv2 -> RFCv3: - use miscdevice framework (removing the carma class) - add bitfile readback capability to the programmer RFCv1 -> RFCv2: - change comments to kerneldoc format - Kconfig improvements - use the videobuf_dma_sg API in the programmer - updates for Freescale DMAEngine DMA_SLAVE API changes Information about the CARMA board: The CARMA board is essentially an MPC8349EA MDS reference design with a 1GHz ADC and 4 high powered data processing FPGAs connected to the local bus. It is all packed into a compact PCI form factor. It is used at the Owens Valley Radio Observatory as the main component in the correlator system. For more information, see this webpage, maintained by the board's hardware engineer: http://www.mmarray.org/~dwh/carma_board/index.html These drivers are the necessary pieces to get the data processing FPGAs working and producing data. Despite the fact that the hardware is custom and we are the only users, I'd still like to get the drivers upstream. Several people have suggested that this is possible. Some further patches will be forthcoming. I have a driver for the LED subsystem and the PPS subsystem. The LED register layout is expected to change soon, so I won't post the driver until that is finished. The PPS driver will be posted seperately from this patch series; it is very generic. Thanks to everyone who has provided comments on earlier versions! Ira W.
