This is work of Michel Arruat, recommitted by Alessandro.  These
svec-specific files match what the previous commit did for spec code.
We are thus using the new register table, sdb support, and
carrier-provided VIC support for interrupts.

driver: major rewrite, with carrier dma-ops and other things · 1598de1a

Michel Arruat authored Mar 07, 2014

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

```
Although the file is not yet used (it will be used by svec code),
it is a common file in several projects, so I pick it now to shrink
the diff from the code base currently under test.  The file comes
from current master of svec-sw, which is unchanged since release 2013-12.

spec-sw: added as a submodule · 4a111a42

By referring to our spec-sw subdirectory, we ensure versions are matched.
Also, we'll later need to include "spec.h", for carrier-specific DMA
code: we'd better not refer to ../spec-sw by default.

lib: support POLLERR when waiting for input samples · dce8b527

Alessandro Rubini authored Oct 30, 2013

Every function that is sable to wait for a timeout now may return -1
with FMCADC_EDISABLED. The new zio commits support that by returning
POLLERR when using poll(2) over a control file descriptor and the
trigger is disabled.  A non-zio driver may support something similar.

Thus, an application may disable the trigger to unlock with error
any thread waiting for an input block.
