| Subject: arm64: dts: allwinner: a64: bananapi-m64: Enable RGMII RX/TX delay on |
| PHY |
| |
| From: Chen-Yu Tsai <wens@csie.org> |
| |
| [ Upstream commit 1a9a8910b2153cd3c4f3f2f8defcb853ead3b1fd ] |
| |
| The Ethernet PHY on the Bananapi M64 has the RX and TX delays |
| enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins. |
| |
| Fix the phy-mode description to correct reflect this so that the |
| implementation doesn't reconfigure the delays incorrectly. This |
| happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e |
| rx/tx delay config"). |
| |
| Fixes: e7295499903d ("arm64: allwinner: bananapi-m64: Enable dwmac-sun8i") |
| Fixes: 94f442886711 ("arm64: dts: allwinner: A64: Restore EMAC changes") |
