Oh OK thanks.

Hi Tony,

these signals come from a TI CDCM61002 (U30 on the board's
schematics). It's hardwired to 100mHZ output.

Is this the 100MHz clock from PCIe? Just like on dm814x-evm as noted
in the workaround thread below:

[PATCH 2/4] ARM: dts: dm8168-evm: add the external reference clock for SATA

2017-03-13 Thread Bartosz Golaszewski 
This board has an external oscillator supplying the reference clock
signal for SATA. Its rate is fixed at 100Mhz. Add a corresponding
device tree node.
