Introduce new compatible strings for the J722S to add this support to the drivers. This is a prerequisite for the Single-Pair Ethernet interface of the TQ-Systems MBa67xx baseboard for the TQMa67xx SoM, which will be submitted separately. For SGMII to actually work on the J722S, the am65-cpsw needs to be extended as well, which has been submitted for net-next: https://patchwork.kernel.org/project/netdevbpf/list/?series=1075806 Fallback compatible strings allow for the patches to be applied in any order and to go through different trees without breaking existing functionality. v3: - Drop am65-cpsw changes from this series, they need to go through net-next - Fix missing PHY_GMII_SEL_RGMII_ID_MODE and PHY_GMII_SEL_FIXED_TX_DELAY in gmii-sel driver for RGMII delay mode configuration v2: - Keep support for the AM64 compatible strings as a fallback, adjust commit messages - Drop reference to AM64_CPSW_QUIRK_CUT_THRU flag, which only exists in the TI vendor kernel Nora Schiffer (5): dt-bindings: phy: ti: phy-j721e-wiz: Add ti,j722s-wiz-10g compatible dt-bindings: phy: ti: phy-gmii-sel: Add ti,j722s-phy-gmii-sel compatible phy: ti: phy-j721e-wiz: add support for J722S SoC family phy: ti: gmii-sel: add support for J722S SoC family arm64: dts: ti: k3-j722s-main: use J722S compatibles for WIZ, gmii-sel and CPSW3G .../bindings/phy/ti,phy-gmii-sel.yaml | 24 ++++++++++++------- .../bindings/phy/ti,phy-j721e-wiz.yaml | 20 ++++++++++------ arch/arm64/boot/dts/ti/k3-j722s-main.dtsi | 12 ++++++++-- drivers/phy/ti/phy-gmii-sel.c | 13 ++++++++++ drivers/phy/ti/phy-j721e-wiz.c | 24 +++++++++++++++++++ 5 files changed, 75 insertions(+), 18 deletions(-) -- TQ-Systems GmbH | Mühlstraße 2, Gut Delling | 82229 Seefeld, Germany Amtsgericht München, HRB 105018 Geschäftsführer: Detlef Schneider, Rüdiger Stahl, Stefan Schneider https://www.tq-group.com/
