And make sure this is done for the MLO_AN_PHY case, where it actually
makes sense, contrary to b53_adjust_link() which only did it for
fixed-PHY configurations where it does not make sense.

Call b53_adjust_531x5_rgmii() and b53_adjust_5325_mii() from
b53_phylink_mac_config() when we have a fixed PHY in preparation for removing
b53_adjust_link(). Also move b53_adjust_63xx_rgmii() to
b53_phylink_mac_config() where it logically belongs.

Just like what b53_adjust_link() does, force flow control for the
BCM5301X CPU port(s) by forcing rx_pause and tx_pause in
b53_phylink_mac_link_up(). Preparatory step for getting rid of
b53_adjust_link().

After commit f86ad77faf24 ("net: dsa: bcm_sf2: Utilize b53_{enable,
disable}_port"), bcm_sf2.c no longer calls b53_eee_enable_set(), and all
its callers are in b53_common.c.
We also need to move it, because it is called within b53_common.c before
its definition, and we want to avoid forward declarations.

b53_get_mac_eee() sets both eee_enabled and eee_active, and then
returns zero.
dsa_user_get_eee(), which calls this function, will then continue to
call phylink_ethtool_get_eee(), which will return -EOPNOTSUPP if there
is no PHY present, otherwise calling phy_ethtool_get_eee() which in
turn will call genphy_c45_ethtool_get_eee().
genphy_c45_ethtool_get_eee() will overwrite eee_enabled and eee_active
with its own interpretation from the PHYs settings and negotiation
result.
Thus, when there is no PHY, dsa_user_get_eee() will fail with
-EOPNOTSUPP, meaning eee_enabled and eee_active will not be returned to
userspace. When there is a PHY, eee_enabled and eee_active will be
overwritten by phylib, making the setting of these members in
b53_get_mac_eee() entirely unnecessary.
Remove this code, thus simplifying b53_get_mac_eee().

Device driver structures are shared between all devices that they
match, and thus nothing should never write to the device driver
structure through the phydev->drv pointer. Let's make this pointer

Pull firewire fix from Takashi Sakamoto:
"A fix to suppress a warning about unreleased IRQ for 1394 OHCI
hardware when disabling MSI.
In Linux kernel v6.5, a PCI driver for 1394 OHCI hardware was
optimized into the managed device resources. Edmund Raile points out
that the change brings the warning about unreleased IRQ at the call of
pci_disable_msi(), since the API expects that the relevant IRQ has
already been released in advance.
As long as the API is called in .remove callback of PCI device
operation, it is prohibited to maintain the IRQ as the part of managed
device resource. As a workaround, the IRQ is explicitly released at
.remove callback, before the call of pci_disable_msi().
pci_disable_msi() is legacy API nowadays in PCI MSI implementation. I
have a plan to replace it with the modern API in the development for
the future version of Linux kernel. So at present I keep them as is"

When the i2c error condition occurred and master state was not
idle, the master irq function will goto complete state without any
other interrupt handling. It would cause dummy irq expected print.
Under this condition, assign the irq_status into irq_handle.
For example, when the abnormal start / stop occurred (bit 5) with
normal stop status (bit 4) at same time. Then the normal stop status
would not be handled and it would cause irq expected print in
the aspeed_i2c_bus_irq.
...
aspeed-i2c-bus x. i2c-bus: irq handled != irq.
