net: ti: am65-cpsw-nuss: Ignore disabled ethernet ports

2025-11-27T15:27:03Z

Currently, the bind callback of the driver namely am65_cpsw_nuss_bind() registers all ethernet ports including the ones that have been disabled in the device-tree. Since the ports that have been disabled are ought to be ignored, fix the implementation to register only the enabled ports as indicated by their 'status' in their respective device-tree node.

net: ethernet: ti: am65-cpsw: fix up PHY mode for fixed RGMII TX delay

2025-10-10T17:07:44Z

The am65-cpsw driver currently sets the SEL_RGMII_IDMODE flag in a MAC's mode register to enable or disable the TX delay. While this was supported for earlier generations of the CPSW controller, the datasheets of all modern TI SoCs using the am65-cpsw MAC state that the TX delay is fixed, and the SEL_RGMII_IDMODE bit is documented as reserved in most of them. Furthermore, while it was found that this bit does in fact disable the TX delay, [1] states that this setting is truly unsupported by TI and not just undocumented. Following the clarification of the rgmii* phy-mode values in the Linux DT bindings in [2], the Linux am65-cpsw driver was changed in [3] to account for the fixed TX delay by fixing up the mode passed to the PHY driver; a similar fixup already existed in the TI icssg-prueth driver. [4] followed up on this by explicitly clearing the SEL_RGMII_IDMODE flag to handle the case where it is set by the bootloader or other firmware before Linux. With the above changes, Device Trees that set the recommended "rgmii-id" mode are now appearing in Linux 6.17+. Avoid setting the unsupported SEL_RGMII_IDMODE flag for such Device Trees, and instead fix up the PHY interface mode, thus aligning the U-Boot driver with the Linux kernel.

net: ti: am65-cpsw-nuss: Define bind method for CPSW driver

2025-08-20T17:06:18Z

CPSW driver is defined as UCLASS_MISC driver which needs to be probed explicitly. Define bind method for CPSW driver to scan and bind ethernet-ports with UCLASS_ETH driver which will eventually probe CPSW driver and avoid probing CPSW driver explicitly. Signed-off-by: Chintan Vankar

net: ti: icssg: Read firmware name from device-tree

2025-07-10T14:41:18Z

Update the ICSSG PRU Ethernet driver to read PRU/RTU/TXPRU firmware names from the Device Tree using the "firmware-name" property, instead of relying on the hard-coded firmware names. The firmware names are parsed during prueth_probe() and stored in the prueth->firmwares for each slice. The driver now uses these dynamically loaded names when starting the PRU cores. This change improves flexibility and allows firmware selection to be controlled via the device tree, making the driver more adaptable to different platforms and firmware configurations.

net: ti: am65-cpsw-nuss: invoke phy_config() in driver's .start callback

2025-04-28T19:24:56Z

Currently, the phy_config() API is invoked by the driver only once since it has been probed. While this works in general, it doesn't allow the driver to bring the PHY back to its default reset state. As a result, the driver might not be able to recover the PHY from a bad state. To address this, move phy_config() into the driver's start callback (am65_cpsw_start()). Apart from providing the means to recover the PHY in the event of failure, the implementation is in line with the idea of "reset and configure" that is already followed by am65_cpsw_start() when it comes to programming the CPSW MAC.
