net: airoha_eth: fix mt7531 mdio related initialization bug

2026-06-23T11:13:16Z

Private data isn't ready during bind time. The call of dev_get_priv() function will return NULL. Thus we can't save mdio device pointer and use it later during probe. To solve an issue, we will move mt7531 mdio device binding to the probing function of 'airoha-eth' driver. All GDM ports (except of GDM1) are connected directly to their PHYs, so corresponding mdio bus will be automatically probed during PHY setup. GDM1 ports differ from other GDM ports. It connected to the airoha switch device. The mt7531 mdio bus is used to manage link state of airoha switch device ports (LAN ports 1-4 corresponds to PHYs 0x09-0x0C). Therefore, manual probing of mt7531 mdio bus is required to be able set/query states of corresponding LAN ports.

net: airoha: probe airoha switch mdio on airoha_eth probing

2026-03-31T14:43:28Z

Airoha switch mdio maybe used not only by GDM1, but also by other GDM ports (ex: as21xxx phy connected to GDM2 port). So it's better probe airoha switch mdio a bit early in the airoha_eth_probe() code. Also remove useless eth_phy_set_mdio_bus() call and related code. Signed-off-by: Mikhail Kshevetskiy

net: airoha: use mt7531 mdio for GDM1

2026-03-12T14:53:41Z

Current code just bind mt7531 mdio with it's driver, so mdio device may not be probed and hense not usable. This patch: * Forces probing of mt7531 mdio for GDM1 port * Renames the mt7531 mdio bus interface to 'mt7531-mdio'. We may have multiple available MDIO, so the name 'mdio' isn't descriptive enough. * Sets mdio bus for the GDM port device Signed-off-by: Mikhail Kshevetskiy

net: airoha: makes PCS support optional

2026-03-12T14:53:41Z

It's not possible to disable PCS support just now, an7581 u-boot will not compile. This patch fixes an issue. Signed-off-by: Mikhail Kshevetskiy

net: airoha: fill in support for PCS/PHY in Airoha Ethernet driver

2026-03-12T14:53:41Z

Add required changes to call PCS function to configure the Serdes Port. The Ethernet driver is adapted following Upstream Kernel node structure. Function calling order is the same of Phylink upstream kernel. With the PCS support, also add support for attaching PHY. With "in-band-status" set in DT for the managed property, a rudimental support for SFP module is present. Signed-off-by: Christian Marangi

net: airoha: init switch before GDM port initialization

2026-03-12T11:49:35Z

Call airoha_switch_init() before creating GDM instances, so if allocation of GDM port fails, early created GDM instances will work normally. Signed-off-by: Mikhail Kshevetskiy

net: airoha: do not call airoha_fe_init() from GDM port independent code

2026-03-12T11:49:35Z

We should not call airoha_fe_init() from GDM port independent code, because it do a GDM specific things. Makes airoha_fe_maccr_init() and airoha_fe_init() port dependent and call them from airoha_eth_port_probe() Signed-off-by: Mikhail Kshevetskiy

net: airoha: declare airoha_eth_port as U_BOOT_DRIVER()

2026-03-12T11:49:35Z

Declare airoha_eth_port as U_BOOT_DRIVER(), fix airoha_alloc_gdm_port() to lookup a driver instead of direct airoha_eth_port usage. Signed-off-by: Mikhail Kshevetskiy

net: airoha: avoid out of boundary writing/access to gdm_port_str[] array

2026-03-12T11:49:35Z

In the case of an7581 possible GDM port id are: 1, 2 and 4. Initialization of port GDM4 will lead to out of boundary writing to gdm_port_str[] array. Let's increase the array size by 1 to avoid it. Signed-off-by: Mikhail Kshevetskiy

net: airoha: add initial support for multiple GDM port

2026-03-12T11:49:35Z

Rework the driver to support multiple GDM port. The driver is split to main driver as a MISC driver with forced probe (by using the DM_FLAG_PROBE_AFTER_BIND) and each GDM port register a ETH driver. This permit a 1:1 implementation with the linux kernel driver and permit to use the same exact DT nodes. Signed-off-by: Christian Marangi
