6.0.1 - 2022-01-11
==================
Changed
-------
- hdl: ip_cores have been updated

Fixed
-----
- sw: use of invalid pointer that could lead to a kernel oops
- sw: change completion order to prevent SVEC bugs

On SVEC carriers we do need to handle shots one by one to be able to
reconfigure the VME DMA window. To handle it we make use of the
completion mechanism: we transfer a shot and we wait its completion,
and then we do the next one.  The completion goes toghether with the
ZIO block, therefore the completion variable is stored togheter with
the block. However, in the fa_dma_complete() code we were cleaning up
the block too soon, so the completion variable is unusable.

Anticipating the completion fixes the problem.

6.0.0 - 2021-09-10
==================
Added
-----
- hdl: configurable auto byte swap in hardware, useful for SVEC to reduce software complexity
- hdl,sw: DMA data is always little-endian
- sw: software version validation against FPGA version
- bld: flawfinder check on software tools

Changed
-------
- sw: offsets are not anymore in uV but they are just raw values

Fixed
-----
- sw: security fixes detected by flawfinder
- sw: fixes detected by checkpatch.pl
- sw: style fixes detected by checkpatch.pl
- sw: improve compatibility with newer ( > 3.10) Linux kernel versions

This reverts commit e2d435fb.

Apparently the temperature issue has nothing to do with the signal
stabilization in FPGA

The serdes does not lock if the ADC chip is not configured before. We
did not need this before because we were not changing the ADC chip
operational mode, but now we ask the chip to use a different number of
bits.

This goes against what described in the ZIO framework, but it is
actually a source of problems because the framework is largely
unmaintained.

With this patch the driver play only with raw values. It will be part
of the library duty to propose a different convention.

The data coming out from the FMC-ADC-110M FPGA is always using the
little-endian byte order. This means that we need to fix the byte
order only on big-endian CPUs.

This allows to improve performances on SVEC-based designs since there
is no need anymore to fix the endianness in software becuase it is
already done in hardware.

`get_seconds` disappeared in kernel 5.11 and onwards,
it is now required to call `ktime_get_real_seconds`.

`setup_timer` is no longer available in kernel 4.15 and onwards,
in favor of `timer_setup`.
Before, we could pass an argument to the callback function as an
unsigned int (generally used with a pointer cast), but now the timer
itself is passed and we retrieve the container struct with a new
macro `from_timer` which is uses `container_of`.
The flags parameter can be set as 0 for the same behavior.
