| Subject: [PATCH] ARM: dts: sun7i: lamobo-r1: Fix CPU port RGMII settings |
| |
| commit 0cdefd5b5485ee6eb3512a75739d09a4090176ed upstream. |
| |
| The CPU port of the BCM53125 is configured with RGMII (no delays) but |
| this should actually be RGMII with transmit delay (rgmii-txid) because |
| STMMAC takes care of inserting the transmitter delay. This fixes |
| occasional packet loss encountered. |
| |
| Fixes: d7b9eaff5f0c ("ARM: dts: sun7i: Add BCM53125 switch nodes to the lamobo-r1 board") |
