Lars-Peter Clausen 853342b201 altera: adi_jesd204: Disable FPLL phase alignment mode
Enabling the phase alignment mode of the FPLL seems to break manual
re-calibration, which is required when changing the lane rates. The
calibration seems to select the wrong VCO frequency band and the PLL no
longer locks.

Disable phase alignment mode for now, this has a negative effects on
deterministic latency, but it is better than not working at all.

Waiting for feedback from Altera/Intel on how to make manual re-calibration
work in phase alignment mode.

Lars-Peter Clausen dd1b1c89f9 jesd204: jesd204_rx: Don't expose internal states on the status interface
The DEGLITCH state of the RX state machine is a workaround for misbehaving
PHYs. It is an internal state and an implementation detail and it does not
really make sense to report through the status interface.

Rework things so that DEGLITCH state is reported as part of the CGS state
on the external status interface.

Lars-Peter Clausen e6aacd2f56 axi_dmac: Better support debug IDs when ID_WIDTH != 3
The current layout of the debug ID register assumes that the ID_WIDTH is 3.
Change things so that the padding 0 width depends on the ID_WIDTH
parameter so that we end up with the same register layout regardless of the
value of ID_WIDTH.

Also split things into two registers, this allows for an ID_WIDTH up to 8
(which should hopefully be enough for all practical applications).

Redesign the axi_dacfifo, to increase the supported datarates.
Major modifications:

  + Both the AXI write and AXI read transaction are controlled by two
FSM, to increase redability of the code.
  + Support all the possible burst lengths [0..225], handles the last
fractional burst on both sides correctly.
  + Common reset architecture throughout the design, all the internal
registers and memories are reset on the posedge of dma_xfer_req
  + Delete all Altera related sources, for Altera projects
avl_dacfifo should be used.

Lars-Peter Clausen 0108d01043 library: Add JESD204 PHY wrapper for Arria10 Native PHY
Add a wrapper that instantiates the Arria10 Native PHY and configures it
for JESD204 operation. The datapath width is set to 4 octets per beat.

The maximum lane rate that is achievable with hard-logic PCS included in
the PHY is below the requirements of the JESD204 for some of the PHY speed
grades. For projects that require a lane rate that is higher than what the
hard-logic PCS can support a soft-logic PCS module can be instantiated. The
external interface of the jesd204_phy is identical regardless of whether
soft- or hard-logic PCS is used.

Lars-Peter Clausen d345a1e31a jesd204: jesd204_tx: Add dummy valid for the TX data interface
The Xilinx tools are quite forgiving when it comes to required signals on
standard interfaces, which is why it was possible to define a AXI streaming
interface without the required valid signal.

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.

Lars-Peter Clausen f730f14d16 jesd204: ilas_mem: Rework to be more Altera friendly
Currently the ILAS memory for the receive register map uses a shift
register with variable tap output for storing the ILAS information. This
maps very efficiently onto the primitives found in Xilinx FPGAs. But there
is no equivalent primitive in Altera FPAGs resulting in increased
utilization from having to implement the structure in pure logic.

Change the ILAS memory so it uses a simple dual port RAM for storing the
data. This has slightly increased utilization on Xilinx platforms (but
still good enough) and highly decreased utilization on Altera platforms.

One side effect of this change is that since the RAM output is synchronous
reading the ILAS memory registers will take one extra clock cycle.

Lars-Peter Clausen 4acb91bedb jesd204: axi_jesd204_{rx,tx}: Add external link domain reset
Currently the reset for the link clock domain is generated internally in
the axi_jesd204_{rx,tx} peripheral. The reset is controlled by through the
register map.

Add an additional external reset for link clock domain. The link clock
domain is kept in reset if either the internal reset or the external reset
is asserted.

This for example allows the fabric to keep the domain in reset if the clock
is not yet stable.

The status of the external reset can be queried from the register map.

Lars-Peter Clausen cefb2b062e util_adcfifo: Remove always false check
dma_raddr is only incremented if it is less than dma_waddr_rel_s.
dma_waddr_rel_s is always less or equal to adc_waddr_rel << RATIO and
adc_waddr_rel is less than DMA_ADDR_LIMIT >> RATIO.

By induction we can conclude that this means that dma_raddr will always be
less then DMA_ADDR_LIMIT and the check for this will always evaluate to
false can be removed.

Lars-Peter Clausen a46b9cfa5a util_adcfifo: Fix data corruption at faster DMA clock rates
When the DMA clock to ADC data rate ratio exceeds a certain threshold it is
possible that an erroneous dma_waddr_rel toggle event is generated. This
causes the last address of the previous DMA transfer to be transferred to
the DMA domain. And the DMA side will start reading from the FIFO even
though data is not available yet.

This results in data corruption with the current transfer containing data
from the previous transfer.

The root cause here is that the toggle signal CDC synchronizer register are
reset in the DMA when a new transfer starts, but not in the ADC domain,
causing a potential mismatch and the incorrect toggle event. To fix this
remove the reset from the DMA side. This is OK since the registers are
self-resetting if the reset signal is asserted for more than 3 clock cycles.
