Will you keep maintaining this, including porting the clocking changes #1939 / m-labs/misoc#129 ?

[kaolpr]

I believe we can support it both in TechnoSystem and on WUT (both sites have boards).

We can wait with this merge until both #1939 and m-labs/misoc#129 are approved and merged so I can port changes.

[sbourdeauducq]

@kaolpr Sync RTIO is merged now. Is this PR ready?

[kaolpr]

I'll update to latest master and will be ready tomorrow.

[sbourdeauducq]

Great. Corresponding MiSoC PR is also OK?

[kaolpr]

@sbourdeauducq Sorry, I didn't manage to test it on hardware before my winter vacation. I'll verify operation for this PR and m-labs/misoc#130 just after coming back on Feb 21st.

[kaolpr]

@sbourdeauducq I've made updates to both to this PR and MiSoC. Please take a look at rtio_clocking.rs modifications. As there is no Si5324 available, most of the contents are disabled via #[cfg(si5324_as_synthesizer)].

And sorry that it took so long.

[sbourdeauducq]

As there is no Si5324 available, most of the contents are disabled via #[cfg(si5324_as_synthesizer)].

We don't have this anymore since synchronous RTIO clocking. Your change breaks Kasli and KC705.

[kaolpr]

Can I use has_rtio_crg for that purpose? Genesys2 will only have _SysCRG?

[sbourdeauducq]

Probably has_si5324. And please test on Kasli and KC705.

[kaolpr]

Modified to use has_si5324. Checked Kasli with hardware, but don't have KC705 around. However firmware builds fine for all 3 target platforms.
