net: ftgmac100: Add SoC reset support for RMII mode
This patch series adds support for an optional reset line to the
ftgmac100 ethernet controller, as used on Aspeed SoCs. On these SoCs,
the internal MAC reset is not sufficient to reset the RMII interface.
By providing a SoC-level reset via the device tree "resets" property,
the driver can properly reset both the MAC and RMII logic, ensuring
correct operation in RMII mode.
The series includes:
- Device tree binding update to document the new "resets" property.
- Addition of MAC1/2/3/4 reset definitions for AST2600.
- Driver changes to assert/deassert the reset line as needed.
This improves reliability and initialization of the MAC in RMII mode

Use addrconf_add_dev() instead of ipv6_find_idev() in
addrconf_gre_config() so that we don't just get the inet6_dev, but also
install the default ff00::/8 multicast route.
Before commit 3e6a0243ff ("gre: Fix again IPv6 link-local address
generation."), the multicast route was created at the end of the
function by addrconf_add_mroute(). But this code path is now only taken
in one particular case (gre devices not bound to a local IP address and
in EUI64 mode). For all other cases, the function exits early and
addrconf_add_mroute() is not called anymore.
Using addrconf_add_dev() instead of ipv6_find_idev() in
addrconf_gre_config(), fixes the problem as it will create the default
multicast route for all gre devices. This also brings
addrconf_gre_config() a bit closer to the normal netdevice IPv6
configuration code (addrconf_dev_config()).

net: phy: microchip: LAN88xx reliability fixes
This patch series improves the reliability of the Microchip LAN88xx
PHYs, particularly in edge cases involving fixed link configurations or
forced speed modes.
Patch 1 assigns genphy_soft_reset() to the .soft_reset hook to ensure
that stale link partner advertisement (LPA) bits are properly cleared
during reconfiguration. Without this, outdated autonegotiation bits may
remain visible in some parallel detection cases.
Patch 2 restricts the 100 Mbps workaround (originally intended to handle
cable length switching) to only run when the link transitions to the
PHY_NOLINK state. This prevents repeated toggling that can confuse
autonegotiating link partners such as the Intel i350, leading to
unstable link cycles.
Both patches were tested on a LAN7850 (with integrated LAN88xx PHY)
against an Intel I350 NIC. The full test suite - autonegotiation, fixed
link, and parallel detection - passed successfully.

Restrict the 100Mbit forced-mode workaround to link-down transitions
only, to prevent repeated link reset cycles in certain configurations.
The workaround was originally introduced to improve signal reliability
when switching cables between long and short distances. It temporarily
forces the PHY into 10 Mbps before returning to 100 Mbps.
However, when used with autonegotiating link partners (e.g., Intel i350),
executing this workaround on every link change can confuse the partner
and cause constant renegotiation loops. This results in repeated link
down/up transitions and the PHY never reaching a stable state.
Limit the workaround to only run during the PHY_NOLINK state. This ensures
it is triggered only once per link drop, avoiding disruptive toggling
while still preserving its intended effect.
Note: I am not able to reproduce the original issue that this workaround
addresses. I can only confirm that 100 Mbit mode works correctly in my
test setup. Based on code inspection, I assume the workaround aims to
reset some internal state machine or signal block by toggling speeds.
However, a PHY reset is already performed earlier in the function via
phy_init_hw(), which may achieve a similar effect. Without a reproducer,
I conservatively keep the workaround but restrict its conditions.

Enable .soft_reset for the LAN88xx PHY driver by assigning
genphy_soft_reset() to ensure that the phylib core performs a proper
soft reset during reconfiguration.
Previously, the driver left .soft_reset unimplemented, so calls to
phy_init_hw() (e.g., from lan88xx_link_change_notify()) did not fully
reset the PHY. As a result, stale contents in the Link Partner Ability
(LPA) register could persist, causing the PHY to incorrectly report
that the link partner advertised autonegotiation even when it did not.
Using genphy_soft_reset() guarantees a clean reset of the PHY and
corrects the false autoneg reporting in these scenarios.

Implement ETHTOOL_GRXFH over Netlink. The number of flow types is
reasonable (around 20) so report all of them at once for simplicity.
Do not maintain the flow ID mapping with ioctl at the uAPI level.
This gives us a chance to clean up the confusion that come from
RxNFC vs RxFH (flow direction vs hashing) in the ioctl.
Try to align with the names used in ethtool CLI, they seem to have
stood the test of time just fine. One annoyance is that we still
call L4 ports the weird names, but I guess they also apply to IPSec
(where they cover the SPI) so it is what it is.

Looks like some drivers (ena, enetc, fbnic.. there's probably more)
consider ETHER_FLOW to be legitimate target for flow hashing.
I'm not sure how intentional that is from the uAPI perspective
vs just an effect of ethtool IOCTL doing minimal input validation.
But Netlink will do strict validation, so we need to decide whether
we allow this use case or not. I don't see a strong reason against
it, and rejecting it would potentially regress a number of drivers.
So update the comments and flow_type_hashable().

Wa_15015404425 only needs to be applied on PTL platforms with an A step
compute die. There is no way to map PCI revid to the compute die
stepping. The easiest way to figure out compute die stepping our end is
to map the media IP's stepping to the compute die. For PTL, compute die
has an A stepping if and only if the media IP's stepping is also A-step
(This relationship is determined on a per platform basis and just
happens to be this way on PTL).
In addition this workaround is a chicken-and-egg problem. Wa_15015404425
requires that all register reads be preceded by four dummy MMIO writes
(including during early driver init and even pre-OS firmware). The
driver needs to perform some MMIO reads during init which include the
GMD_ID register that contains the Media IPs stepping. To handle this in
the safest manner assume the workaround applies to all of PTL during
driver probe and deactivate the workaround after.
The overall solution becomes a set of two workarounds:
* 15015404425 - a Device OOB workaround that's always active for PTL
* 15015404425_disable - a GT OOB workaround that applies to PTL
platfroms with a B0 or later stepping
The first of these workarounds issues dummy MMIO writes we do when
reading registers. The second guards logic that disables the first once
we have the necessary information later in the probe process.
v2: rename SoC to device, avoid null pointer dereference, update commit
message.
v3: rebase
v5: move disable check into xe_device_probe to avoid linking in xe_wa
into xe_pci, reword commit message
v6: squash extension and b0 support into 1 patch

Some workarounds need to be able to be applied ahead of any GT
initialization for example 15015404425. This patch creates XE_DEVICE_WA
macro, in the same vein as XE_WA. This macro can be used ahead of GT
initialization, and can be tracked in sysfs. This should alleviate some
of the complexities that exist in i915.
v2: name change SoC to Device, address style issues
v5: split into separate patch from RTP changes, put oob within a struct,
move the initiation of oob workarounds into xe_device_probe_early(),
clean up the comments around XE_WA.

When a ring reset happens, amdgpu calls drm_dev_wedged_event() using
struct amdgpu_task_info *ti as one of the arguments. After using *ti, a
call to amdgpu_vm_put_task_info(ti) is required to correctly track its
lifetime.
However, it's called from a place that the ring reset path never reaches
due to a goto after drm_dev_wedged_event() is called. Move
amdgpu_vm_put_task_info() bellow the exit label to make sure that it's
called regardless of the code path.
amdgpu_vm_put_task_info() can only accept a valid address or NULL as
argument, so initialise *ti to make sure we can call this function if
*ti isn't used.

pci_msix_write_tph_tag() takes the per device MSI descriptor mutex and then
invokes msi_domain_get_virq(), which takes the same mutex again. That

Move the lock guard after the invocation of msi_domain_get_virq() to fix
this.
