| Subject: arm64: dts: uniphier: Change phy-mode to RGMII-ID to enable delay |
| pins for RTL8211E |
| |
| From: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> |
| |
| [ Upstream commit dcabb06bf127b3e0d3fbc94a2b65dd56c2725851 ] |
| |
| UniPhier LD20 and PXs3 boards have RTL8211E ethernet phy, and the phy have |
| the RX/TX delays of RGMII interface using pull-ups on the RXDLY and TXDLY |
| pins. |
| |
| After the commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx |
| delay config"), the delays are working correctly, however, "rgmii" means |
| no delay and the phy doesn't work. So need to set the phy-mode to |
| "rgmii-id" to show that RX/TX delays are enabled. |
