Add support to power on and power off the SERDES PHY which is used by the CPSW MAC. ========= Changelog ========= v2 -> v3: 1. Run 'make DT_CHECKER_FLAGS=-m dt_binding_check' and fix errors and warnings corresponding to the patch for: Documentation/devicetree/bindings/net/ti,k3-am654-cpsw-nuss.yaml with the latest dt-schema and yamllint. v1 -> v2: 1. Drop all patches corresponding to SGMII mode. This is done since I do not have a method to test SGMII in the standard mode which uses an SGMII PHY. The previous series used SGMII in a fixed-link mode, bypassing the SGMII PHY. I will post the SGMII patches in a future series after testing them. 2. Drop all patches corresponding to fixed-link in the am65-cpsw driver. This is done since PHYLINK takes care of fixed-link automatically and there is no need to deal with fixed-link in a custom fashion. 3. Fix indentation errors in k3-am65-cpsw-nuss.yaml. 4. Remove the stale code which tries to power on and power off the CPSW MAC's phy, since the CPSW MAC's phy driver does not support it. 5. Rename the function "am65_cpsw_init_phy()" to "am65_cpsw_init_serdes_phy()", to indicate that the phy corresponds to the SERDES. 6. Invoke "am65_cpsw_disable_serdes_phy()" as a part of the cleanup that is associated with the "am65_cpsw_nuss_remove()" function. v2: https://lore.kernel.org/r/20221018085810.151327-1-s-vadapalli@ti.com/ v1: https://lore.kernel.org/r/20220914095053.189851-1-s-vadapalli@ti.com/ Siddharth Vadapalli (3): dt-bindings: net: ti: k3-am654-cpsw-nuss: Update bindings for J721e CPSW9G net: ethernet: ti: am65-cpsw: Enable QSGMII mode for J721e CPSW9G net: ethernet: ti: am65-cpsw: Add support for SERDES configuration .../bindings/net/ti,k3-am654-cpsw-nuss.yaml | 33 ++++++++- drivers/net/ethernet/ti/am65-cpsw-nuss.c | 73 +++++++++++++++++++ 2 files changed, 102 insertions(+), 4 deletions(-)
