Add ADI JESD204 link layer cores The ADI JESD204 link layer cores are a implementation of the JESD204 link layer. They are responsible for handling the control signals (like SYNC and SYSREF) and controlling the link state machine as well as performing per-lane (de-)scrambling and character replacement. Architecturally the cores are separated into two components. 1) Protocol processing cores (jesd204_rx, jesd204_tx). These cores take care of the JESD204 protocol handling. They have configuration and status ports that allows to configure their behaviour and monitor the current state. The processing cores run entirely in the lane_rate/40 clock domain. They have a upstream and a downstream port that accept and generate raw PHY level data and transport level payload data (which is which depends on the direction of the core). 2) Configuration interface cores (axi_jesd204_rx, axi_jesd204_tx). The configuration interface cores provide a register map interface that allow access to the to the configuration and status interfaces of the processing cores. The configuration cores are responsible for implementing the clock domain crossing between the lane_rate/40 and register map clock domain. These new cores are compatible to all ADI converter products using the JESD204 interface. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

The Altera tools are more strict and wont allow this. Add a dummy valid signal to the TX data interface to make the tools happy. For now the signal does not do anything, in the future it might be used to detect an underflow condition on the data interface and report this through the status interface.

jesd204_tx: Add dynamic multi-link support A multi-link is a link where multiple converter devices are connected to a single logic device (FPGA). All links involved in a multi-link are synchronous and established at the same time. For a TX link this means that the FPGA receives multiple SYNC signals, one for each link. The state machine of the TX link peripheral must combine those SYNC signals into a single SYNC signal that is asserted when either of the external SYNC signals is asserted. Dynamic multi-link support must allow to select to which converter devices on the multi-link the SYNC signal is propagated too. This is useful when depending on the use case profile some converter devices are supposed to be disabled. Add the cfg_links_disable[0x081] register for multi-link control and propagate its value to the TX FSM.

jesd204: Xilinx: NP=12 support To support deterministic latency with non-power of two octets per frame (F=3,6) the interface width towards the transport layer must be resized to match integer multiple of frames. e.g Input datapath width = 4; Output datpath width = 6; for F=3 one beat contains 2 frames for F=6 one beat contains 1 frame The width change is realized with a gearbox. Due the interface width change the single clock domain core is split in two clock domains. - Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b - lane rate / 20 for input datapath width of 8 octets 8b10b - lane rate / 66 for input datapath width of 8 octets 64b66b - Device clock : Link clock * input data path width / output datapath width Interface to transport layer and SYSREF handling is moved to device clock domain. The configuration interface reflects the dual clock domain. If Input and Output datapath width matches, the gearbox is no longer required, a single clock can be connected to both clocks.

Add ADI JESD204 link layer cores The ADI JESD204 link layer cores are a implementation of the JESD204 link layer. They are responsible for handling the control signals (like SYNC and SYSREF) and controlling the link state machine as well as performing per-lane (de-)scrambling and character replacement. Architecturally the cores are separated into two components. 1) Protocol processing cores (jesd204_rx, jesd204_tx). These cores take care of the JESD204 protocol handling. They have configuration and status ports that allows to configure their behaviour and monitor the current state. The processing cores run entirely in the lane_rate/40 clock domain. They have a upstream and a downstream port that accept and generate raw PHY level data and transport level payload data (which is which depends on the direction of the core). 2) Configuration interface cores (axi_jesd204_rx, axi_jesd204_tx). The configuration interface cores provide a register map interface that allow access to the to the configuration and status interfaces of the processing cores. The configuration cores are responsible for implementing the clock domain crossing between the lane_rate/40 and register map clock domain. These new cores are compatible to all ADI converter products using the JESD204 interface. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

jesd204_rx/tx: make SYSREF IOB placement optional In case when the SYSREF is connected to an FPGA IO which has a limitation on the IOB register IN_FF clock line and the required ref clock is high we can't use the IOB registers. e.g. the max clock rate on zcu102 HP IO FF is 312MHz but ref clock is 375MHz; If IOB is used in this case a pulse width violation is reported. This change makes the IOB placement selectable in such case or for targets which don't require class 1 operation.
