* Bartosz Golaszewski [off-list ref] [170313 09:45]:
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: http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/p/181083/671141 Regards, Tony
