127 description: Default value of the rx-sample-delay-ns property.
128 This value will be used if the property is not explicitly defined
129 for a SPI slave device. See below.
146 description: SPI Rx sample delay offset, unit is nanoseconds.
147 The delay from the default sample time before the actual
148 sample of the rxd input signal occurs. The "rx_sample_delay"
149 is an optional feature of the designware controller, and the
150 upper limit is also subject to controller configuration.
