Sebastien Bourdeauducq 175f8b8ccc drtio/gth_ultrascale: generate multiplied RTIO clock from BUFG_GT (#792) 2019-01-03 20:14:18 +08:00
Sebastien Bourdeauducq cc58318500 siphaser: autocalibrate skew using RX synchronizer
* removes the hardcoded, (poorly) manually determined skew value
* does not need si5324_clkout_fabric anymore (broken on Sayma RTM due to wrong IO voltage)

Sebastien Bourdeauducq 251d90c3d5 drtio: clear read request in satellite only after reply has been fully sent
Otherwise, chan_sel become invalid before the end of the packet, which
can cause the interconnect to invalidate i_timestamp and i_data which results
in corruption of the end of the packet.
