To overcome the issue, a check is made to extract the right SAR
information using the device mode which is currently being used.

The int3472-discrete driver can enter an error path after initialising
int3472->clock.ena_gpio, but before it has registered the clock. This will
cause a NULL pointer dereference, because clkdev_drop() is not null aware.
Instead of guarding the call to skl_int3472_unregister_clock() by checking
for .ena_gpio, check specifically for the presence of the clk_lookup, which
will guarantee clkdev_create() has already been called.

Commit a7d53dbbc70a ("platform/x86: intel_scu_ipc: Increase virtual

is 5-10 seconds. Adjust the timeout value to the higher of those i.e 10
seconds, to account for situations where the 5 seconds is insufficient
for disconnect command success.

Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.
It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.
The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);
For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).
As a result, _parse_integer() exits with result zero (rv):
rv = 0;
while (1) {
...
if (val >= base)-> (2 >= 2)
break;
...
rv++;
...
}
And _kstrtoull() in their turn will fail:
if (rv == 0)
return -EINVAL;

Arm FF-A driver fixes for v5.15
Couple of fixes addressing issues when FFA driver is build as a module.
One adds the device unregistration which was missing and causes issue
when loading the module second time after unloading once. Another one
adds the missing remove callback on the ffa bus which was missing due
to which modules depending on FFA(e.g. OPTEE) will fail to remove the
device and faults next time that module is loaded again.

Tested on SD5200T TB3 dock which has Fresco Logic FL1100 USB 3.0 Host

Before this patch streaming video from USB cam made mouse and keyboard
connected to the same USB bus unusable. Also video was jerky.
With this patch streaming video doesn't have any effect on other
periferals and video is smooth.

The command ring pointer is located at [6:63] bits of the command
ring control register (CRCR). All the control bits like command stop,
abort are located at [0:3] bits. While aborting a command, we read the
CRCR and set the abort bit and write to the CRCR. The read will always
give command ring pointer as all zeros. So we essentially write only
the control bits. Since we split the 64 bit write into two 32 bit writes,
there is a possibility of xHC command ring stopped before the upper
dword (all zeros) is written. If that happens, xHC updates the upper
dword of its internal command ring pointer with all zeros. Next time,
when the command ring is restarted, we see xHC memory access failures.
Fix this issue by only writing to the lower dword of CRCR where all
control bits are located.

Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
at least, if the xHC halts on a particular TRB due to an error then
the DCS field in the Out Endpoint Context maintained by the hardware
is not updated with the current cycle state.
Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
from the TRB that the xHC stopped on.

Bridging, and possibly other upper stack gizmos, adds the
lower device's netdev->dev_addr to its own uc list, and
then requests it be deleted when the upper bridge device is
removed. This delete request also happens with the bridging
vlan_filtering is enabled and then disabled.
Bonding has a similar behavior with the uc list, but since it
also uses set_mac to manage netdev->dev_addr, it doesn't have
the same the failure case.
Because we store our netdev->dev_addr in our uc list, we need
to ignore the delete request from dev_uc_sync so as to not
lose the address and all hope of communicating. Note that
ndo_set_mac_address is expressly changing netdev->dev_addr,
so no limitation is set there.

Similar to commit 6087175b7991 ("net: dsa: mt7530: use independent VLAN
learning on VLAN-unaware bridges"), software forwarding between an
unoffloaded LAG port (a bonding interface with an unsupported policy)
and a mv88e6xxx user port directly under a bridge is broken.
We adopt the same strategy, which is to make the standalone ports not
find any ATU entry learned on a bridge port.
Theory: the mv88e6xxx ATU is looked up by FID and MAC address. There are
as many FIDs as VIDs (4096). The FID is derived from the VID when
possible (the VTU maps a VID to a FID), with a fallback to the port
based default FID value when not (802.1Q Mode is disabled on the port,
or the classified VID isn't present in the VTU).
The mv88e6xxx driver makes the following use of FIDs and VIDs:
- the port's DefaultVID (to which untagged & pvid-tagged packets get
classified) is 0 and is absent from the VTU, so this kind of packets is
processed in FID 0, the default FID assigned by mv88e6xxx_setup_port.
- every time a bridge VLAN is created, mv88e6xxx_port_vlan_join() ->
mv88e6xxx_atu_new() associates a FID with that VID which increases
linearly starting from 1. Like this:
bridge vlan add dev lan0 vid 100 # FID 1
bridge vlan add dev lan1 vid 100 # still FID 1
bridge vlan add dev lan2 vid 1024 # FID 2
The FID allocation made by the driver is sub-optimal for the following
reasons:
(a) A standalone port has a DefaultPVID of 0 and a default FID of 0 too.
A VLAN-unaware bridged port has a DefaultPVID of 0 and a default FID
of 0 too. The difference is that the bridged ports may learn ATU
entries, while the standalone port has the requirement that it must
not, and must not find them either. Standalone ports must not use
the same FID as ports belonging to a bridge. All standalone ports
can use the same FID, since the ATU will never have an entry in
that FID.
(b) Multiple VLAN-unaware bridges will all use a DefaultPVID of 0 and a
default FID of 0 on all their ports. The FDBs will not be isolated
between these bridges. Every VLAN-unaware bridge must use the same
FID on all its ports, different from the FID of other bridge ports.
(c) Each bridge VLAN uses a unique FID which is useful for Independent
VLAN Learning, but the same VLAN ID on multiple VLAN-aware bridges
will result in the same FID being used by mv88e6xxx_atu_new().
The correct behavior is for VLAN 1 in br0 to have a different FID
compared to VLAN 1 in br1.
This patch cannot fix all the above. Traditionally the DSA framework did
not care about this, and the reality is that DSA core involvement is
needed for the aforementioned issues to be solved. The only thing we can
solve here is an issue which does not require API changes, and that is
issue (a), aka use a different FID for standalone ports vs ports under
VLAN-unaware bridges.
The first step is deciding what VID and FID to use for standalone ports,
and what VID and FID for bridged ports. The 0/0 pair for standalone
ports is what they used up till now, let's keep using that. For bridged
ports, there are 2 cases:
- VLAN-aware ports will never end up using the port default FID, because
packets will always be classified to a VID in the VTU or dropped
otherwise. The FID is the one associated with the VID in the VTU.
- On VLAN-unaware ports, we _could_ leave their DefaultVID (pvid) at
zero (just as in the case of standalone ports), and just change the
port's default FID from 0 to a different number (say 1).
However, Tobias points out that there is one more requirement to cater to:
cross-chip bridging. The Marvell DSA header does not carry the FID in
it, only the VID. So once a packet crosses a DSA link, if it has a VID
of zero it will get classified to the default FID of that cascade port.
Relying on a port default FID for upstream cascade ports results in
contradictions: a default FID of 0 breaks ATU isolation of bridged ports
on the downstream switch, a default FID of 1 breaks standalone ports on
the downstream switch.
So not only must standalone ports have different FIDs compared to
bridged ports, they must also have different DefaultVID values.
IEEE 802.1Q defines two reserved VID values: 0 and 4095. So we simply
choose 4095 as the DefaultVID of ports belonging to VLAN-unaware
bridges, and VID 4095 maps to FID 1.
For the xmit operation to look up the same ATU database, we need to put
VID 4095 in DSA tags sent to ports belonging to VLAN-unaware bridges
too. All shared ports are configured to map this VID to the bridging
FID, because they are members of that VLAN in the VTU. Shared ports
don't need to have 802.1QMode enabled in any way, they always parse the
VID from the DSA header, they don't need to look at the 802.1Q header.
We install VID 4095 to the VTU in mv88e6xxx_setup_port(), with the
mention that mv88e6xxx_vtu_setup() which was located right below that
call was flushing the VTU so those entries wouldn't be preserved.
So we need to relocate the VTU flushing prior to the port initialization
during ->setup(). Also note that this is why it is safe to assume that
VID 4095 will get associated with FID 1: the user ports haven't been
created, so there is no avenue for the user to create a bridge VLAN
which could otherwise race with the creation of another FID which would
otherwise use up the non-reserved FID value of 1.
[ Currently mv88e6xxx_port_vlan_join() doesn't have the option of
specifying a preferred FID, it always calls mv88e6xxx_atu_new(). ]
mv88e6xxx_port_db_load_purge() is the function to access the ATU for
FDB/MDB entries, and it used to determine the FID to use for
VLAN-unaware FDB entries (VID=0) using mv88e6xxx_port_get_fid().
But the driver only called mv88e6xxx_port_set_fid() once, during probe,
so no surprises, the port FID was always 0, the call to get_fid() was
redundant. As much as I would have wanted to not touch that code, the
logic is broken when we add a new FID which is not the port-based
default. Now the port-based default FID only corresponds to standalone
ports, and FDB/MDB entries belong to the bridging service. So while in
the future, when the DSA API will support FDB isolation, we will have to
figure out the FID based on the bridge number, for now there's a single
bridging FID, so hardcode that.
Lastly, the tagger needs to check, when it is transmitting a VLAN
untagged skb, whether it is sending it towards a bridged or a standalone
port. When we see it is bridged we assume the bridge is VLAN-unaware.
Not because it cannot be VLAN-aware but:
- if we are transmitting from a VLAN-aware bridge we are likely doing so
using TX forwarding offload. That code path guarantees that skbs have
a vlan hwaccel tag in them, so we would not enter the "else" branch
of the "if (skb->protocol == htons(ETH_P_8021Q))" condition.
- if we are transmitting on behalf of a VLAN-aware bridge but with no TX
forwarding offload (no PVT support, out of space in the PVT, whatever),
we would indeed be transmitting with VLAN 4095 instead of the bridge
device's pvid. However we would be injecting a "From CPU" frame, and
the switch won't learn from that - it only learns from "Forward" frames.
So it is inconsequential for address learning. And VLAN 4095 is
absolutely enough for the frame to exit the switch, since we never
remove that VLAN from any port.

The VLAN support in mv88e6xxx has a loaded history. Commit 2ea7a679ca2a
("net: dsa: Don't add vlans when vlan filtering is disabled") noticed
some issues with VLAN and decided the best way to deal with them was to
make the DSA core ignore VLANs added by the bridge while VLAN awareness
is turned off. Those issues were never explained, just presented as
"at least one corner case".
That approach had problems of its own, presented by
commit 54a0ed0df496 ("net: dsa: provide an option for drivers to always
receive bridge VLANs") for the DSA core, followed by
commit 1fb74191988f ("net: dsa: mv88e6xxx: fix vlan setup") which
applied ds->configure_vlan_while_not_filtering = true for mv88e6xxx in
particular.
We still don't know what corner case Andrew saw when he wrote
commit 2ea7a679ca2a ("net: dsa: Don't add vlans when vlan filtering is
disabled"), but Tobias now reports that when we use TX forwarding
offload, pinging an external station from the bridge device is broken if
the front-facing DSA user port has flooding turned off. The full
description is in the link below, but for short, when a mv88e6xxx port
is under a VLAN-unaware bridge, it inherits that bridge's pvid.
So packets ingressing a user port will be classified to e.g. VID 1
(assuming that value for the bridge_default_pvid), whereas when
tag_dsa.c xmits towards a user port, it always sends packets using a VID
of 0 if that port is standalone or under a VLAN-unaware bridge - or at
least it did so prior to commit d82f8ab0d874 ("net: dsa: tag_dsa:
offload the bridge forwarding process").
In any case, when there is a conversation between the CPU and a station
connected to a user port, the station's MAC address is learned in VID 1
but the CPU tries to transmit through VID 0. The packets reach the
intended station, but via flooding and not by virtue of matching the
existing ATU entry.
DSA has established (and enforced in other drivers: sja1105, felix,
mt7530) that a VLAN-unaware port should use a private pvid, and not
inherit the one from the bridge. The bridge's pvid should only be
inherited when that bridge is VLAN-aware, so all state transitions need
to be handled. On the other hand, all bridge VLANs should sit in the VTU
starting with the moment when the bridge offloads them via switchdev,
they are just not used.
This solves the problem that Tobias sees because packets ingressing on
VLAN-unaware user ports now get classified to VID 0, which is also the
VID used by tag_dsa.c on xmit.

"There is one build fix for Arm platforms that ended up impacting most

The CONFIG_QCOM_SCM dependency have caused a number of randconfig

agreed on in the end is to make this symbol selected by any driver

CONFIG_COMPILE_TEST.
To make this work on all architectures, the drivers/firmware/Kconfig
file needs to be included for all architectures to make the symbol
itself visible.
In a separate discussion, we found that a sound driver patch that is
pending for v5.16 needs the same change to include this Kconfig file,
so the easiest solution seems to have my Kconfig rework included in
v5.15.

Some old IPs do not provide the hardware feature register.
On these IPs, this register is read 0x00000000.
In old driver version, this feature was handled but a regression came
with the commit f10a6a3541b4 ("stmmac: rework get_hw_feature function").
Indeed, this commit removes the return value in dma->get_hw_feature().
This return value was used to indicate the validity of retrieved
information and used later on in stmmac_hw_init() to override
priv->plat data if this hardware feature were valid.
This patch restores the return code in ->get_hw_feature() in order
to indicate the hardware feature validity and override priv->plat
data only if this hardware feature is valid.

Fixes for omaps for v5.15
Few regression fixes for omaps for the v5.15-rc cycle. There is a fix
for boot time hangs that can happen on some am335x devices that started
when the pruss devicetree nodes were added. The other fixes are less
critical:
- Fix compiler warning for sysc_init_soc() that got recently introduced
- Fix external abort for am335x pruss as otherwise some am335x will hang
- Use CLKDM_NOAUTO quirk also for dra7 dcan1
- Fix older NAND device node regression for omap3-sdp

If acpi_pci_find_companion() is called for a device whose parent
pointer is NULL, it will crash when attempting to get the ACPI
companion of the parent due to a NULL pointer dereference in
the ACPI_COMPANION() macro.
This was not a problem before commit 375553a93201 ("PCI: Setup ACPI
fwnode early and at the same time with OF") that made pci_setup_device()
call pci_set_acpi_fwnode() and so it allowed devices with NULL parent
pointers to be passed to acpi_pci_find_companion() which is the case
in pci_iov_add_virtfn(), for instance.
Fix this issue by making acpi_pci_find_companion() check the device's
parent pointer upfront and bail out if it is NULL.
While pci_iov_add_virtfn() can be changed to set the device's parent
pointer before calling pci_setup_device() for it, checking pointers
against NULL before dereferencing them is prudent anyway and looking
for ACPI companions of virtual functions isn't really useful.
