2024-04-16net: dsa: microchip: drop unneeded MODULE_ALIASKrzysztof Kozlowski1-7/+0
The ID table already has respective entry and MODULE_DEVICE_TABLE and creates proper alias for SPI driver. Having another MODULE_ALIAS causes the alias to be duplicated.

2024-02-01net: dsa: Add KSZ8567 switch supportPhilippe Schenker1-0/+5
This commit introduces support for the KSZ8567, a robust 7-port Ethernet switch. The KSZ8567 features two RGMII/MII/RMII interfaces, each capable of gigabit speeds, complemented by five 10/100 Mbps MAC/PHYs.

2023-10-27net: dsa: microchip: Refactor switch shutdown routine for WoL preparationOleksij Rempel1-4/+1
Centralize the switch shutdown routine in a dedicated function, ksz_switch_shutdown(), to enhance code maintainability and reduce redundancy. This change abstracts the common shutdown operations previously duplicated in ksz9477_i2c_shutdown() and ksz_spi_shutdown(). This refactoring is a preparatory step for an upcoming patch to avoid reset on shutdown if Wake-on-LAN (WoL) is enabled.

2023-05-30net: dsa: microchip: add an enum for regmap widthsVladimir Oltean1-1/+1
It is not immediately obvious that this driver allocates, via the KSZ_REGMAP_TABLE() macro, 3 regmaps for register access: dev->regmap[0] for 8-bit access, dev->regmap[1] for 16-bit and dev->regmap[2] for 32-bit access. In future changes that add support for reg_fields, each field will have to specify through which of the 3 regmaps it's going to go. Add an enum now, to denote one of the 3 register access widths, and make the code go through some wrapper functions for easier review and further modification.

Add support for the KSZ9896 6-port Gigabit Ethernet Switch to the ksz9477 driver. Although the KSZ9896 is already listed in the device tree binding documentation since a1c0ed24fe9b (dt-bindings: net: dsa: document additional Microchip KSZ9477 family switches) the chip id (0x00989600) is not recognized by ksz_switch_detect() and rejected by the driver. The KSZ9896 is similar to KSZ9897 but has only one configurable MII/RMII/RGMII/GMII cpu port. Signed-off-by: Romain Naour <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2022-09-05net: dsa: microchip: lan937x: add interrupt support for port phy linkArun Ramadoss1-0/+2
This patch enables the interrupts for internal phy link detection for LAN937x. The interrupt enable bits are active low. There is global interrupt mask for each port. And each port has the individual interrupt mask for TAS. QCI, SGMII, PTP, PHY and ACL. The first level of interrupt domain is registered for global port interrupt and second level of interrupt domain for the individual port interrupts. The phy interrupt is enabled in the lan937x_mdio_register function. Interrupt from which port is raised will be detected based on the interrupt host data.

The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs. The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. The SGMII port may interface to a fiber optic transceiver. This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.
