The clock-names property is required because the driver requests
the clock by name and not the index.
Update the example to use &clk instead of &nf_clk for the clocks
property to avoid confusion with the clock-names property "nf_clk".

|
Estimated Board delay. The value includes the total round trip
|
|
delay for the signals and is used for deciding on values associated
|
|
with data read capture. The example formula for SDR mode is the
|
|
following.
|
|
board delay = RE#PAD delay + PCB trace to device + PCB trace from device
|
|
+ DQ PAD delay
