the time.

net: phy: Add the Airoha EN8811H PHY driver

2025-04-16T22:48:13+00:00

Add the driver for the Airoha EN8811H 2.5 Gigabit PHY. The PHY supports
100/1000/2500 Mbps with auto negotiation only.

The driver uses two firmware files, for which updated versions are added to
linux-firmware already.

Based on the Linux upstream 8811 driver code(air_en8811h.c),
I have modified the relevant process to align with the U-Boot boot sequence.
and have validated this on Banana Pi BPI-R3 Mini.

The MD32 FW is currently stored in eMMC partition 1 on Banana Pi BPI-R3 Mini,
and it is loaded from there.

net: phy: ksz90x1: Simplify ksz9131_config_rgmii_delay

2025-03-19T02:38:51+00:00

We can call phy_modify_mmd() instead of manually calling drv->readext()
and drv->writeext().

net: phy: ksz90x1: Load skew values from device tree

2025-03-19T02:38:51+00:00

Various signal skew values may be set in the device tree for the ksz9131
Ethernet PHY. For example, the RZ/G2L board requires non-default values
for rxc-skew-psec & txc-skew-psec.

This is based on the ksz9131 phy driver in Linux v6.11.

net: phy: ksz90x1: Handle ksz9131 LED errata

2025-03-19T02:38:51+00:00

Micrel KSZ9131 PHY LED behavior is not correct when configured in
Individual Mode, LED1 (Activity LED) is in the ON state when there is
no-link.

Workaround this by setting bit 9 of register 0x1e after verifying that
the LED configuration is Individual Mode.

This issue is described in KSZ9131RNX Silicon Errata DS80000693B [*]
and according to that it will not be corrected in a future silicon
revision.

net: miiphybb: Drop bb_miiphy_alloc()/bb_miiphy_free() and struct bb_miiphy_bus

2025-03-11T22:05:57+00:00

These functions are no longer necessary, remove them.
The struct bb_miiphy_bus is no longer necessary either,
remove it as well.

net: miiphybb: Pass struct mii_dev directly to bb_miiphy_read/write()

2025-03-11T22:05:57+00:00

Access to MDIO bus private data can be provided by both
struct mii_dev .priv member and struct bb_miiphy_bus .priv
member, use the former directly and remove .priv from the
later. Drop unused bb_miiphy_getbus(). This removes any
dependency on struct bb_miiphy_bus from the miiphybb code,
except for helper functions which will be removed later.

net: miiphybb: Pass struct bb_miiphy_bus_ops directly to bb_miiphy_read/write()

2025-03-11T22:05:57+00:00

The access to struct bb_miiphy_bus_ops via ops pointer in
struct bb_miiphy_bus is not necessary with wrappers added
in previous patch. Pass the ops pointer directly to both
bb_miiphy_read() and bb_miiphy_write() functions.

net: miiphybb: Split off struct bb_miiphy_bus_ops

2025-03-11T22:05:57+00:00

Move miiphybb operations into separate struct bb_miiphy_bus_ops
structure, add pointer to struct bb_miiphy_bus_ops into the base
struct bb_miiphy_bus and access the ops through this pointer in
miiphybb generic code. The variable reshuffling in miiphybb.c
cannot be easily avoided.

net: miiphybb: Use container_of() in bb_miiphy_getbus()

2025-02-26T17:26:57+00:00

Replace the name based look up in bb_miiphy_getbus() with trivial
container_of() call. This works because the struct bb_miiphy_bus
always embeds the matching struct mii_dev . This also makes the
code much simpler and more efficient.
