| Message-ID | <tkBub-3kO-29@gated-at.bofh.it> |
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.

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