[PATCH v2] net: dsa: sja1105: fix sja1105_parse_rgmii_delays()

From: Oleksij Rempel
Date: Mon Nov 25 2019 - 06:44:04 EST


This function was using configuration of port 0 in devicetree for all ports.
In case CPU port was not 0, the delay settings was ignored. This resulted not
working communication between CPU and the switch.

Fixes: f5b8631c293b ("net: dsa: sja1105: Error out if RGMII delays are requested in DT")
