@ -19,6 +19,9 @@ Clock Properties:
- fsl,max-adj Maximum frequency adjustment in parts per billion.
- fsl,extts-fifo The presence of this property indicates hardware
support for the external trigger stamp FIFO.
- little-endian The presence of this property indicates the 1588 timer
IP block is little-endian mode. The default endian mode
is big-endian.
These properties set the operational parameters for the PTP
clock. You must choose these carefully for the clock to work right.
