The 156.25MHz fixed clock is a crystal. The 100MHz clocks (there are actually 3) come from a Renesas 6V49205B at address 69 on i2c0. There is no driver for this device (and as far as I know all you can do with the 100MHz clocks is gate them), so I have chosen to model it as a single fixed clock. Note: the SerDes1 lane numbering for the LS1046A is *reversed*. This means that Lane A (what the driver thinks is lane 0) uses pins SD1_TX3_P/N. Because this will break ethernet if the serdes is not enabled, enable the serdes driver by default on Layerscape. Signed-off-by: Sean Anderson --- This depends on [1].
