Florent Kermarrec 79ac09316a interconnect/axi/AXIBurst2Beat: Fix BURST_WRAP case. 2021-08-06 16:41:58 +02:00
Florent Kermarrec 1ce48a973b clock/lattice_ecp5: Fix and rework 4-output solver implementation.
The implementation was causing regressions on actual designs, rework done:
- Only keep a common iteration loop as before.
- Add iteration on CLKO dividers (to fall in the VCO range).
- Do the iterations as before, if while doing it we find a clock suitable for feedback: just use it.
- If no feedback clock has been found: create it (if at least one free output available, if not raise an error).

George Hilliard 8954041a93 clock/lattice_ecp5/ECP5PLL: Only consider non-dpa clocks as feedback
Dynamically adjusting the phase of a feedback will cause it to unlock.
The phase adjust ports are shared by all the outputs, so there is no
technical way to prevent this.  Allow the user to indicate that they
will not adjust a clock when requesting an output by setting
uses_dpa=False, and only consider those that the user has promised not
to use.

Florent Kermarrec f31f9a20f0 boards: remove and switch to litex_boards.
Keeping board definition files directly in LiteX is no longer useful since we are already relying on board
definitions files from LiteX-Boards (https://github.com/litex-hub/litex-boards) in various benches/projects
and having definitions files directly in LiteX creates confusion/additional work.

For projects using board definition files from LiteX, the litex.boards import can just be replaced with litex_boards:

from litex.boards.platforms import kc705

from litex_boards.platforms import kc705

Pawel Sagan ce49990084 Extend I2S capabilities
This commit:
* adds the support for I2S standard mode,
* extends I2S left justified mode,
* allows to configure sample size for tx/rx in 1-32 bits range,
* implements I2S master mode,
* allows to concatenate channels or used the padded mode.

This required to rework the FSM.
