^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) ZHAW InES PTP time stamping IP core
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) The IP core needs two different kinds of nodes.  The control node
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) lives somewhere in the memory map and specifies the address of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) control registers.  There can be up to three port handles placed as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) attributes of PHY nodes.  These associate a particular MII bus with a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) port index within the IP core.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) Required properties of the control node:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) - compatible:		"ines,ptp-ctrl"
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) - reg:			physical address and size of the register bank
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) Required format of the port handle within the PHY node:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) - timestamper:		provides control node reference and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 			the port channel within the IP core
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)
