Dual clock mode is introduced in link layer to support different
datapath widths on the transport layer than on physical layer.
- Link clock : lane rate / 40 for input datapath width of 4 octets 8b10b
- Device clock : Link clock * input data path width / output datapath width
Supports four clock configurations, single or dual clock mode with or
without external device clock.
The configuration interface reflects the dual clock domain.
Support multiple clock monitors in a block.
Before this change the clock monitor had to be named with a fix name
preventing multiple instances of the clock monitor.
In phase aligned mode the fPLL uses an external feedback path to better
align the phase of the PLL output to the phase of the external reference
clock.
This mode is required for deterministic latency to be able to sample SYSREF
which is source synchronous to the external reference clock signal.
So far phase aligned mode had been disabled since manual PLL calibration
would fail in this mode under certain (unknown) circumstances and dynamic
reconfiguration of the PLL would not work.
The latest Intel Arria 10 transceiver datasheet contains instructions for
the proper calibration sequence to make it work when the PLL is configured
for phase aligned mode. Software has been updated accordingly, so enable
phase aligned mode.

Define INPUT_PIPELINE parameter, which can be used to activate the
REGISTER_INPUTS parameter of the PHY. This parameter will add an
additional register stage into the incoming parallel data stream.
It can be used to relax the timing margin between the PHY and Link modules.
This patch contains an initial effort to support the Stratix 10
architecture in our JESD204 framework.
Several instances were updated, doing simple context switching using the
DEVICE_FAMILY system parameter:
- xcvr_reset_control
- lane PLL (ATX PLL)
- link PLL (fPLL)
- native XCVR instance
Apart from the slightly different parameters of the instances above,
there were small differences at the reconfiguration Avalon_MM interface.
The link_pll_reset_control is required just for Arria10, so in case of
Stratix10 it isn't instantiated.
In Stratix 10 architecture there are several additional ports of the
xcvr_reset_control module that must be connected to the native XCVR
instance or tied to GND.
The following xcvr_reset_control ports were defined and connected to the
XCVR:
- rx|tx_analogreset_stat
- rx|tx_digitalreset_stat
- pll_select
* jesd204b: add bonding clocks feature (fix for some routing issues)
* intel/adi_jesd204: bonding clock feature invisible in QSYS GUI if number of lanes is less than 6
* intel/adi_jesd204: clock network option renamed according to intel documentation
* intel/adi_jesd204: Hide BONDING_CLOCKS_EN parameter in RX mode

In Subclass 1 mode, we need to use a separate clock (device clock) to
drive the link and transport layer of the interface. Implement the
required infrastructure for this scenario.
The clock domain crossing will be done in by the TX|RX_FIFO in the PCS.
In Subclass 1 mode an external device clock (core clock) is used,
instead of the PCS output clock, to drive the link and transport layer.
Define an additional parameter, which can be used to enable clock input
port for the PHY module, which can be used as rx|tx_coreclkin source.
