sysref is not coming on ZCU102 board.

Hi,

We are using two AD9371 with one AD9528 chip. For now, we have connected one AD9371. 

Our problem is sysref is not coming from the AD9528 output channels. We have configured AD9528 channel 0 and channel 2 for AD9371 DEV_CLK and SYSREF. And at the same time channel4 and channel5 for FPGA Clk and sysref. Our device tree is looking OK. And we have probed the sysref-req in ad9371 driver also. All configuration looks OK. But we are not getting sysref and at the same time peak to peak device clock is 900 mV. AD9371 driver is also printing the ILAS mismatch error.Which section we should look?
