Following some discussion both on & off list, I have volunteered to take
over maintaining the miscellaneous RISC-V devicetrees & soc drivers from
Palmer to ease his load.
So far only SiFive and Microchip have stuff in drivers/soc. For the
former, a SiFive entry exists with a dead GitHub repo - so remove that
to avoid confusion since the patches for drivers/soc & devicetrees will
be routed via my tree & other drivers go through their subsystem trees.
The Microchip directory only contains a RISC-V driver for now, but is
likely to contain drivers for other archs in the future. To that end,
change the PolarFire SoC entry to specifically mention the RISC-V driver
& the new directory level entry does not mention an architecture.

The bridge driver can offload VLANs to the underlying hardware either
via switchdev or the 8021q driver. When the former is used, the VLAN is
marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV'
private flag.
To avoid the memory leaks mentioned in the cited commit, the bridge
driver will try to delete a VLAN via the 8021q driver if the VLAN is not
marked with the previously mentioned flag.
When the VLAN protocol of the bridge changes, switchdev drivers are
notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but
the 8021q driver is also called to add the existing VLANs with the new
protocol and delete them with the old protocol.
In case the VLANs were offloaded via switchdev, the above behavior is
both redundant and buggy. Redundant because the VLANs are already
programmed in hardware and drivers that support VLAN protocol change
(currently only mlx5) change the protocol upon the switchdev attribute
notification. Buggy because the 8021q driver is called despite these
VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to
memory leaks [1] when the VLANs are deleted.
Fix by not calling the 8021q driver for VLANs that were already
programmed via switchdev.

resetting process
Currently, if driver is in phy-imp(phy controlled by imp firmware) mode, as
driver did not update phy link ksettings after initialization process or
not update advertising when getting phy link ksettings from firmware, it
may set incorrect phy link ksettings for firmware in resetting process.
So fix it.

sk->sk_receive_queue is protected by skb queue lock, but for KCM
sockets its RX path takes mux->rx_lock to protect more than just
skb queue. However, kcm_recvmsg() still only grabs the skb queue
lock, so race conditions still exist.
We can teach kcm_recvmsg() to grab mux->rx_lock too but this would
introduce a potential performance regression as struct kcm_mux can
be shared by multiple KCM sockets.
So we have to enforce skb queue lock in requeue_rx_msgs() and handle
skb peek case carefully in kcm_wait_data(). Fortunately,
skb_recv_datagram() already handles it nicely and is widely used by
other sockets, we can just switch to skb_recv_datagram() after
getting rid of the unnecessary sock lock in kcm_recvmsg() and
kcm_splice_read(). Side note: SOCK_DONE is not used by KCM sockets,
so it is safe to get rid of this check too.

A problem about ionic create debugfs failed is triggered with the
following log given:
[ 415.799514] debugfs: Directory 'ionic' with parent '/' already present!
The reason is that ionic_init_module() returns ionic_bus_register_driver()
directly without checking its return value, if ionic_bus_register_driver()
failed, it returns without destroy the newly created debugfs, resulting
the debugfs of ionic can never be created later.
ionic_init_module()

ionic_bus_register_driver()

FDB entries that perform VXLAN encapsulation with an IPv6 underlay hold
a reference on a resource - the KVDL entry where the IPv6 underlay
destination IP is stored. For that, the driver maintains two hash tables:
1. Maps IPv6 to KVDL index
2. Maps {MAC, FID index} to IPv6 address
When a FDB entry is removed, the second table is used to find the relevant
IPv6 address and the first table is used to remove the reference count and
free the index if is not used anymore.
In order for a packet to be forwarded to a single remote VTEP, FDB
entries need to be configured at both the bridge and VXLAN devices' FDB
tables. Both entries are squashed into one {MAC, VLAN/VNI} -> IP entry
in the hardware. Therefore, in case one entry is removed, the entry will
be removed from the hardware and the remaining entry will be unmarked
with 'offload' flag since it is not offloaded anymore.
For example, the two FDB entries should be added to allow packets to be
forwarded via vx10:
$ bridge fdb add dev vx10 aa:bb:cc:dd:ee:ff self static dst 2001:db8:5::1
$ bridge fdb add dev vx10 aa:bb:cc:dd:ee:ff master static vlan 10
When one entry will be removed, the second one will not be offloaded
anymore. When the first entry (in VXLAN FDB) will be removed / will not be
offloaded anymore, the two mappings in IPv6 hash tables will be removed.
In case that the second entry is removed before the first one, unexpected
warnings[1][2] will be shown in user space as a result of removing the
first entry. The issue is that not offloaded entry is removed, the driver
tries to search the relevant entries in the hash tables, does not find them
and therefore warns.
Do not handle removing of not offloaded VXLAN FDB entries, as they were
already removed when the offload flag was removed.

The External Interrupt Controller (EINTC) on all of the supported
MediaTek SoCs does support input debouncing, but not all of them
index the debounce time values (DBNC_SETTING registers) the same way.
Before this change, in some cases, as an example, requesting a debounce
time of 16 milliseconds would mistakenly set the relative DBNC_SETTING
register to 0x2, resulting in a way shorter debounce time of 500uS.
To fix the aforementioned issue, define three different debounce_time
arrays, reflecting the correct register index for each value and for
each register index variant, and make sure that each SoC pinctrl
driver uses the right one.

When Xen domain configures MSI-X, the usual approach is to enable MSI-X
together with masking all of them via the config space, then fill the
table and only then clear PCI_MSIX_FLAGS_MASKALL. Allow doing this via
QEMU running in a stub domain.
Previously, when changing PCI_MSIX_FLAGS_MASKALL was not allowed, the
whole write was aborted, preventing change to the PCI_MSIX_FLAGS_ENABLE
bit too.
Note the Xen hypervisor intercepts this write anyway, and may keep the
PCI_MSIX_FLAGS_MASKALL bit set if it wishes to. It will store the
guest-requested state and will apply it eventually.

port_hwtstamp_get() callback to determine PTP capability, and this
clearly does not work in that case (method is present but returns
-EOPNOTSUPP).
We should not deny PTP on the DSA master for those switches which truly
do not support hardware timestamping.
Create a dsa_port_supports_hwtstamp() method which actually probes for
support by calling port_hwtstamp_get() and seeing whether that returned
-EOPNOTSUPP or not.
Fixes: f685e609a301 ("net: dsa: Deny PTP on master if switch supports it")

MHI driver registers network device without setting the
needs_free_netdev flag, and does NOT call free_netdev() when
unregisters network device, which causes a memory leak.
This patch calls free_netdev() to fix it since netdev_priv
is used after unregister.

Qualcomm ARM64 DTS fixes for 6.1
This fixes the APCS register region on IPQ8074 to not overlap
with adjacent nodes.
It lists the valid LDO modes on a variety of platforms, as this is not
required by the binding and implementation.
The reference clocks for the two UFS instances on SC8280XP are
corrected, to avoid relying on the state left by most versions of the
bootloader.
A number of issues are corrected with regards to the QMP PHY register
ranges on SC8280XP.
SC7280 gains a missing lpass reset region.
Lastly cluster idle is termporarily disabled on SM8250 to avoid issues
with booting the platform, until the last missing pieces lands.

Commit 7d981405d0fd ("soc: imx8m: change to use platform driver") ever
removed the dependency on bootloader for enabling OCOTP clock. It
helped to fix a kexec kernel hang issue. But unfortunately it caused
a regression on CAAM driver and got reverted.
This is the second try to enable the OCOTP clock by directly calling
clock API instead of indirectly enabling the clock via nvmem API.

snd_usbmidi_output_open() has a check of the NULL port with
snd_BUG_ON(). snd_BUG_ON() was used as this shouldn't have happened,
but in reality, the NULL port may be seen when the device gives an
invalid endpoint setup at the descriptor, hence the driver skips the
allocation. That is, the check itself is valid and snd_BUG_ON()
should be dropped from there. Otherwise it's confusing as if it were
a real bug, as recently syzbot stumbled on it.

ASoC: Fixes for v6.1
A relatively large collection of fixes and new platform quirks here,
they're all fairly minor though - the widest possible impact is the fix
to the use of prefixes on regulator names which would have broken any
device that integrates regulators with DAPM and was used in a system
where it had a name prefix assigning to it.
