Additionally, two device-tree overlays are also added: 1. QSGMII mode with the CPSW9G instance via the ENET EXPANSION 1 connector. 2. USXGMII mode with MAC Ports 1 and 2 of the CPSW9G instance via ENET EXPANSION 1 and 2 connectors, configured in fixed-link mode of operation at 5Gbps link speed. Similar to Andrew Davis patch at: https://lore.kernel.org/r/20231117222930.228688-5-afd@ti.com/ for J721E, similar changes are also required for J784S4 to remove dependency on the parent node being a syscon node. This series combines the v1 series at: https://lore.kernel.org/r/20230522092201.127598-1-s-vadapalli@ti.com/ and the patch for Main CPSW2G node that is present in [PATCH v6 2/5] at: https://lore.kernel.org/r/20230721132029.123881-1-j-choudhary@ti.com/ but dropped in it's next version at: https://lore.kernel.org/r/20231019054022.175163-1-j-choudhary@ti.com/ Changes from v1 for J784S4 CPSW9G DT Support: 1. Update serdes_ln_ctrl node in k3-j784s4-main.dtsi to remove dependency on the parent node being a syscon node. 2. The patch for Main CPSW2G node is combined. 3. Update description in k3-j784s4-evm-quad-port-eth-exp1.dtso QSGMII overlay file and add product link for QSGMII daughtercard. 4. Add a comment in k3-j784s4-evm-usxgmii-exp1-exp2.dtso USXGMII overlay file for the serdes_wiz2 node since it uses 156.25 MHz clock for USXGMII. Changes from v6 for J784S4 Main CPSW2G node: 1. Rename node name in k3-j784s4-main.dtsi from main_cpsw2g_pins_default to main_cpsw2g_default_pins, main_cpsw2g_mdio_pins_default to main_cpsw2g_mdio_default_pins and main_phy0 to main_cpsw1_phy0 based on Tony's suggestion at: https://lore.kernel.org/all/20230724045032.GU5194@atomide.com/ Chintan Vankar (1): arm64: dts: ti: k3-j784s4-main: Convert serdes_ln_ctrl node into reg-mux Siddharth Vadapalli (4): arm64: dts: ti: k3-j784s4: Add Main CPSW2G node arm64: dts: ti: k3-j784s4-main: Add CPSW9G nodes arm64: dts: ti: k3-j784s4: Add overlay to enable QSGMII mode with CPSW9G arm64: dts: ti: k3-j784s4: Add overlay for dual port USXGMII mode arch/arm64/boot/dts/ti/Makefile | 11 +- .../ti/k3-j784s4-evm-quad-port-eth-exp1.dtso | 146 +++++++++++++ .../ti/k3-j784s4-evm-usxgmii-exp1-exp2.dtso | 73 +++++++ arch/arm64/boot/dts/ti/k3-j784s4-evm.dts | 47 +++++ arch/arm64/boot/dts/ti/k3-j784s4-main.dtsi | 194 +++++++++++++++++- 5 files changed, 464 insertions(+), 7 deletions(-) create mode 100644 arch/arm64/boot/dts/ti/k3-j784s4-evm-quad-port-eth-exp1.dtso create mode 100644 arch/arm64/boot/dts/ti/k3-j784s4-evm-usxgmii-exp1-exp2.dtso
