This is a major change, work of Michel Arruat, then re-committed as a single commit by Alessandro. The original development happened mainly on the SVEC carrier, and support for SPEC (PCI) was added back at a later time. I (Alessandro) chose to pick individual changes one at a time, for better documentation and later "git blame", up to this point. Now, this is a big commit that completely changes the driver, mainly in the following places: - split carrier-specific from generic code, like the TDC driver is now (this is mainly the dma-specific and irq-specific code) - use of SDB to get base addresses (with new fmc-util file) - use the VIC core to manage interrupts, relying on carrier support - change the field-desc table for the better - add carrier-specific init, reset, exit - split irq and adc-specific stuff out of zio-drv.c - DMA data and interrupt is now different: the timestamp is at end-of-data, thus we don't have the "trigger-happened" interrupt any more - use a work queue for interrupt management, instead of a tasklet, this allows sleeping, which is needed by this code base Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
