Hello The RGMII internal delay is a common setting found in most RGMII capable PHY devices. It was found that many vendor specific device tree properties exist to do the same function. This creates a common property to be used for PHY's that have internal delays for the Rx and Tx paths. If the internal delay is tunable then the caller needs to pass the internal delay array and the return will be the index in the array that was found in the firmware node. If the internal delay is fixed then the caller only needs to indicate which delay to return and if the value is defined then the value in the firmware is returned. This series contains examples of both a configurable delay and a fixed delay.
