 ==== Device tree configuration ====
-The timestamps that are the basis of PTP can be acquired with greater accuracy when they are captured by the ethernet PHY hardware. The RGMII and RMII PHY interface support hardware timestamps, the default phy mode is RGMII.

-The phy-mode can be changed to "rmii" in the device tree header in the linux kernel source arch/arm/boot/dts/sc589-ezkit.dts other board specific sc5xx.dts files. Run "//**bitbake linux-adi -c devshell**//" to enter into linux kernel source code.
