net: dsa: vsc73xx: Implement the tag_8021q VLAN operations

2024-07-15T13:55:15+00:00

This patch is a simple implementation of 802.1q tagging in the vsc73xx driver. Currently, devices with DSA_TAG_PROTO_NONE are not functional. The VSC73XX family doesn't provide any tag support for external Ethernet ports. The only option available is VLAN-based tagging, which requires constant hardware VLAN filtering. While the VSC73XX family supports provider bridging, it only supports QinQ without full implementation of 802.1AD. This means it only allows the doubled 0x8100 TPID. In the simple port mode, QinQ is enabled to preserve forwarding of VLAN-tagged frames.

net: dsa: lan9303: imply SMSC_PHY

2024-05-30T00:11:45+00:00

Both LAN9303 and LAN9354 have internal PHYs on both external ports. Therefore a configuration without SMSC PHY support is non-practical at least and leads to: LAN9303_MDIO 8000f00.mdio:00: Found LAN9303 rev. 1 mdio_bus 8000f00.mdio:00: deferred probe pending: (reason unknown) Signed-off-by: Alexander Sverdlin Reviewed-by: Andrew Lunn Link: https://lore.kernel.org/r/20240528073147.3604083-1-alexander.sverdlin@siemens.com Signed-off-by: Jakub Kicinski

net: dsa: mt7530: select MEDIATEK_GE_PHY for NET_DSA_MT7530_MDIO

2024-01-27T04:31:52+00:00

Quoting from commit 4223f8651287 ("net: dsa: mt7530: make NET_DSA_MT7530 select MEDIATEK_GE_PHY"): Make MediaTek MT753x DSA driver enable MediaTek Gigabit PHYs driver to properly control MT7530 and MT7531 switch PHYs. A noticeable change is that the behaviour of switchport interfaces going up-down-up-down is no longer there. Now, the switch can be used without the PHYs but, at the moment, every hardware design out there that I have seen uses them. For that, it would make the most sense to force the selection of MEDIATEK_GE_PHY for the MDIO interface which currently controls the MT7530 and MT7531 switches.

net: dsa: mt7530: improve and relax PHY driver dependency

2023-08-09T10:22:55+00:00

Different MT7530 variants require different PHY drivers. Use 'imply' instead of 'select' to relax the dependency on the PHY driver, and choose the appropriate driver. Signed-off-by: Daniel Golle Reviewed-by: Simon Horman Reviewed-by: Vladimir Oltean Signed-off-by: David S. Miller

net: dsa: mt7530: introduce driver for MT7988 built-in switch

2023-04-03T09:13:01+00:00

Add driver for the built-in Gigabit Ethernet switch which can be found in the MediaTek MT7988 SoC. The switch shares most of its design with MT7530 and MT7531, but has it's registers mapped into the SoCs register space rather than being connected externally or internally via MDIO. Introduce a new platform driver to support that. Signed-off-by: Daniel Golle Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

Split MT7530 switch driver into a common part and a part specific for MDIO connected switches and multi-chip modules. Move MDIO-specific functions to newly introduced mt7530-mdio.c while keeping the common parts in mt7530.c. Introduce new Kconfig symbol CONFIG_NET_DSA_MT7530_MDIO which is implied by CONFIG_NET_DSA_MT7530. Signed-off-by: Daniel Golle Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: mt7530: use external PCS driver

Implement regmap access wrappers, for now only to be used by the pcs-mtk-lynxi driver. Make use of this external PCS driver and drop the now reduntant implementation in mt7530.c. As a nice side effect the SGMII registers can now also more easily be inspected for debugging via /sys/kernel/debug/regmap.

net: dsa: modularize DSA_TAG_PROTO_NONE

2022-11-23T04:41:45+00:00

There is no reason that I can see why the no-op tagging protocol should be registered manually, so make it a module and make all drivers which have any sort of reference to DSA_TAG_PROTO_NONE select it. Note that I don't know if ksz_get_tag_protocol() really needs this, or if it's just the logic which is poorly written. All switches seem to have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a fallback that never gets used.

net: dsa: LAN9303: Add basic support for LAN9354

2022-09-07T10:06:04+00:00

Adding support for the LAN9354 device by allowing it to use the LAN9303 DSA driver. These devices have the same underlying access and control methods and from a feature set point of view the LAN9354 is a superset of the LAN9303. The MDIO access method has been tested on a SAMA5D3-EDS board with a LAN9354 RMII daughter card. While the SPI access method should also be the same, it has not been tested and as such is not included at this time. Signed-off-by: Jerry Ray Signed-off-by: David S. Miller
