From 5bd78c00d753d4e80e151555565334c475a559d3 Mon Sep 17 00:00:00 2001 From: Siddharth Vadapalli Date: Wed, 26 Oct 2022 13:15:32 +0530 Subject: phy: ti: gmii-sel: Add support for CPSW9G GMII SEL in J721e Each of the CPSW9G ports in J721e support additional modes like QSGMII. Add a new compatible for J721e to support the additional modes. In TI's J721e, each of the CPSW9G ethernet interfaces can act as a QSGMII main or QSGMII-SUB port. The QSGMII main interface is responsible for performing auto-negotiation between the MAC and the PHY while the rest of the interfaces are designated as QSGMII-SUB interfaces, indicating that they will not be taking part in the auto-negotiation process.
