net: airoha: probe airoha switch mdio on airoha_eth probing

2026-03-31T14:43:28+00:00

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.

net: airoha: use mt7531 mdio for GDM1

2026-03-12T14:53:41+00:00

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

net: airoha: makes PCS support optional

2026-03-12T14:53:41+00:00

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

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

2026-03-12T14:53:41+00:00

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.

net: airoha: init switch before GDM port initialization

2026-03-12T11:49:35+00:00

Call airoha_switch_init() before creating GDM instances, so if
allocation of GDM port fails, early created GDM instances will work
normally.

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

2026-03-12T11:49:35+00:00

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()

net: airoha: declare airoha_eth_port as U_BOOT_DRIVER()

2026-03-12T11:49:35+00:00

Declare airoha_eth_port as U_BOOT_DRIVER(), fix airoha_alloc_gdm_port()
to lookup a driver instead of direct airoha_eth_port usage.

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

2026-03-12T11:49:35+00:00

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.

net: airoha: add initial support for multiple GDM port

2026-03-12T11:49:35+00:00

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.

net: airoha_eth: use proper switch node for en7523 case

2026-02-06T15:42:45+00:00

Commit d2145a89bcf6 ("net: airoha: bind MDIO controller on Ethernet load")
uses "airoha,en7581-switch" dts node for finding MDIO childs. This is wrong
for EN7523 SoC. The correct node name should be used instead.
