| Subject: arm64: dts: allwinner: a64: Pine64 Plus: Fix ethernet node |
| |
| From: Jernej Skrabec <jernej.skrabec@siol.net> |
| |
| [ Upstream commit 927f42fcc1b4f7d04a2ac5cf02f25612aa8923a4 ] |
| |
| According to board schematic, PHY provides both, RX and TX delays. |
| However, according to "fix" Realtek provided for this board, only TX |
| delay should be provided by PHY. |
| Tests show that both variants work but TX only PHY delay works |
| slightly better. |
| |
| Update ethernet node to reflect the fact that PHY provides TX delay. |
