This is a backport of netdev/net [1]/[2], expected to be in kernel 6.11
(if not backported to a stable branch).
Since 4fdc7bb8f1 (2024-06-14, switching ath79 from kernel 6.1 to 6.6),
the rtl8366s driver was made to write to bogus PHY MII registers on
ath79/netgear,wndr3800 and family, and likely on other systems using
this switch in a similar manner. The writes were directed to PHY 4 MII
registers 0x0d (13) and 0x0e (14). The rtl8366s data sheet claims these
registers are reserved. These register writes were causing the device to
not maintain link, track link status, or pass traffic on eth1 (labeled
WAN), as eth1 is connected to PHY 4.
0x0d is MII_MMD_CTRL, and 0x0e is MII_MMD_DATA. rtl8366s doesn't appear
to support MMD in any way, and certainly not via the IEEE 802.3 annex
22D "clause 45 over clause 22" protocol implemented by mmd_phy_indirect.
This patch intercepts those attempted register accesses and returns
-EOPNOTSUPP without touching the switch chip. This is implemented by
defining phy_driver::{read,write}_mmd as
genphy_{read,write}_mmd_unsupported for this PHY. A new PHY driver for
this PHY is introduced to achieve that, because this PHY was previously
using genphy_driver, and there is otherwise no clean way to declare lack
of support for these operations.
This was caused by kernel 9b01c885be36 (2023-02-13, in 6.3). The new
genphy_c45_read_eee_abilities call in genphy_read_abilities (called
during phy_probe) was causing an attempted MMD read of (MMIO_MMD_PCS,
MDIO_PCS_EEE_ABLE), which was transformed into an annex 22D
mmd_phy_indirect operation that performed MII register writes to
MII_MMD_CTRL, MII_MMD_DATA, and MII_MMD_CTRL again, followed by another
read from MII_MMD_DATA. This was enough to "scramble" the state of those
two MII registers, which are in fact not used for annex 22D MMD register
access on this device but are reserved and have some other function,
rendering the PHY unusable while so configured. The result of the
bungled MMD read attempt caused the genphy driver to incorrectly believe
that the PHY supported standard EEE, which led to several more attempted
MMD writes and reads, in turn being transformed into writes to these two
MII registers.
rtl8366s does support some pre-IEEE 802.3az EEE standard form of "Green
Ethernet" which the switch driver (local to OpenWrt) already has some
support for. No attempt is made to map the standard operations for this
device.

PMD Global Transmit Disable bit should be cleared for normal operation.
This should be HW default, however I found that on Asus RT-AX89X that uses
AQR113C PHY and firmware 5.4 this bit is set by default.
With this bit set the AQR cannot achieve a link with its link-partner and
it took me multiple hours of digging through the vendor GPL source to find
this out, so lets always clear this bit during .config_init() to avoid a
situation like this in the future.
aqr107_wait_processor_intensive_op() is moved up because datasheet notes
that any changes to this bit are processor intensive.
This is a modified version of patch that got merged upstream as AQR113C
has a separate config_init() upstream.

QCA808x does not currently fill in the possible_interfaces.
This leads to Phylink not being aware that it supports 2500Base-X as well
so in cases where it is connected to a DSA switch like MV88E6393 it will
limit that port to phy-mode set in the DTS.
That means that if SGMII is used you are limited to 1G only while if
2500Base-X was set you are limited to 2.5G only.
Populating the possible_interfaces fixes this, so lets backport the patches
from kernel 6.9.
This also includes a backport of the Phylink PHY validation series from
kernel 6.8 that allows the use of possible_interfaces.
