Hi all,
I have a custom FPGA board based around a ZU11 MPSoC and AD9207 ADC, which is clocked by providing external device reference and SYSREF clocks.
Prior to moving to the custom platform, I had success bringing up the AD9082-FMCA-EBZ board with a commercial ZU11 dev kit, using the ADI reference designs where all clocking is from the HMC7044 PLL. I also got this setup working with external clocks not from this chip, and simply configured the device tree as if this chip were being used, even though the clocks were coming from elsewhere.
With the custom platform, I'd like to have a device tree which properly recognises that the clocks are fixed and external, however, I'm running into issues.
My current device tree reads:

With this device tree, the current draw of the board goes up when the board boots, consistent with the ADC being clocked. From the iio status I see "JESD RX (JTX) Link0 204C PLL locked, PHASE lost, MODE valid" but from the jesd_status utility I get "Failed to find JESD devices"

localhost login:
In the device tree (currently commented out) if I set the jesd204-inputs of the axi_ad9081_adxcvr_rx to be jesd204-inputs = <&refclk 0 FRAMER_LINK0_RX> then I am also required to declare the fixed-clock as a "jesd204-device". This still gets me to the same place.
If I add an HMC7044 to the device tree -- even though there isn't one in hardware! -- then I see the JESD204 state machine going through the appropriate steps for bootup.
I'm hoping that I'm missing something obvious, and there is a simple way to get a fixed clock to serve as the JESD204 reference -- I'd very much appreciate any pointers!
Thanks
Jack
