| Subject: ARM: dts: sun8i: a83t: Enable both RGMII RX/TX delay on Ethernet PHY |
| |
| From: Chen-Yu Tsai <wens@csie.org> |
| |
| [ Upstream commit 57dbe558457bf4042169bc1f334e3b53a8480a1c ] |
| |
| The Ethernet PHY on the Bananapi M3 and Cubietruck Plus have 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: 039359948a4b ("ARM: dts: sun8i: a83t: Enable Ethernet on two boards") |
