ASoC: Fixes for v6.19

A moderately large collection of fixes since I missed a week, plus a few
new device IDs and quirks. It's all fairly minor, including a bunch of
work on the device tree bindings fixes which have no runtime effect.

There's one SoundWire change here exporting a symbol which was required
for a fix to the ASoC SoundWire code.

The soundwire update_status() callback may be called multiple times with

transitioning from UNATTACHED to ATTACHED.

This series fixes the Qualcomm wsa88xx codec drivers that do unnecessary
reinitialisation or potentially fail to initialise at all.

Included is also a related clean up suppressing a related codec variant

this is a pull request of 4 patches for net/main, it super-seeds the
"can 2026-01-14" pull request. The dev refcount leak in patch #3 is
fixed.

The first 3 patches are by Oliver Hartkopp and revert the approach to
instantly reject unsupported CAN frames introduced in
net-next-for-v6.19 and replace it by placing the needed data into the
CAN specific ml_priv.

The last patch is by Tetsuo Handa and fixes a J1939 refcount leak for
j1939_session in session deactivation upon receiving the second RTS.

Merge patch series "can: raw: better approach to instantly reject unsupported CAN frames"

Oliver Hartkopp <socketcan@hartkopp.net> says:

This series reverts commit 1a620a723853 ("can: raw: instantly reject
unsupported CAN frames").

and its follow-up fixes for the introduced dependency issues.

commit 1a620a723853 ("can: raw: instantly reject unsupported CAN frames")
commit cb2dc6d2869a ("can: Kconfig: select CAN driver infrastructure by default")
commit 6abd4577bccc ("can: fix build dependency")
commit 5a5aff6338c0 ("can: fix build dependency")

The reverted patch was accessing CAN device internal data structures
from the network layer because it needs to know about the CAN protocol
capabilities of the CAN devices.

This data access caused build problems between the CAN network and the
CAN driver layer which introduced unwanted Kconfig dependencies and fixes.

The patches 2 & 3 implement a better approach which makes use of the
CAN specific ml_priv data which is accessible from both sides.

With this change the CAN network layer can check the required features
and the decoupling of the driver layer and network layer is restored.

Arnd Bergmann's patch [1] fixed the build dependency problem introduced by
bugfix commit cb2dc6d2869a ("can: Kconfig: select CAN driver infrastructure
by default"). This ended up as commit 6abd4577bccc ("can: fix build

thought was superfluous.

Merge tag 'net-next-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Replace busylock at the Tx queuing layer with a lockless list.

Resulting in a 300% (4x) improvement on heavy TX workloads, sending
twice the number of packets per second, for half the cpu cycles.

- Allow constantly busy flows to migrate to a more suitable CPU/NIC
queue.

Normally we perform queue re-selection when flow comes out of idle,
but under extreme circumstances the flows may be constantly busy.

Add sysctl to allow periodic rehashing even if it'd risk packet
reordering.

- Optimize the NAPI skb cache, make it larger, use it in more paths.

- Attempt returning Tx skbs to the originating CPU (like we already
did for Rx skbs).

- Various data structure layout and prefetch optimizations from Eric.

- Remove ktime_get() from the recvmsg() fast path, ktime_get() is
sadly quite expensive on recent AMD machines.

- Extend threaded NAPI polling to allow the kthread busy poll for
packets.

- Make MPTCP use Rx backlog processing. This lowers the lock
pressure, improving the Rx performance.

- Support memcg accounting of MPTCP socket memory.

- Allow admin to opt sockets out of global protocol memory accounting
(using a sysctl or BPF-based policy). The global limits are a poor
fit for modern container workloads, where limits are imposed using
cgroups.

- Improve heuristics for when to kick off AF_UNIX garbage collection.

- Allow users to control TCP SACK compression, and default to 33% of
RTT.

- Add tcp_rcvbuf_low_rtt sysctl to let datacenter users avoid
unnecessarily aggressive rcvbuf growth and overshot when the
connection RTT is low.

- Preserve skb metadata space across skb_push / skb_pull operations.

- Support for IPIP encapsulation in the nftables flowtable offload.

- Support appending IP interface information to ICMP messages (RFC
5837).

- Support setting max record size in TLS (RFC 8449).

- Remove taking rtnl_lock from RTM_GETNEIGHTBL and RTM_SETNEIGHTBL.

- Use a dedicated lock (and RCU) in MPLS, instead of rtnl_lock.

- Let users configure the number of write buffers in SMC.

- Add new struct sockaddr_unsized for sockaddr of unknown length,
from Kees.

- Some conversions away from the crypto_ahash API, from Eric Biggers.

- Some preparations for slimming down struct page.

- YAML Netlink protocol spec for WireGuard.

- Add a tool on top of YAML Netlink specs/lib for reporting commonly
computed derived statistics and summarized system state.

Driver API:

- Add CAN XL support to the CAN Netlink interface.

- Add uAPI for reporting PHY Mean Square Error (MSE) diagnostics, as
defined by the OPEN Alliance's "Advanced diagnostic features for
100BASE-T1 automotive Ethernet PHYs" specification.

- Add DPLL phase-adjust-gran pin attribute (and implement it in
zl3073x).

- Refactor xfrm_input lock to reduce contention when NIC offloads
IPsec and performs RSS.

- Add info to devlink params whether the current setting is the
default or a user override. Allow resetting back to default.

- Add standard device stats for PSP crypto offload.

- Leverage DSA frame broadcast to implement simple HSR frame
duplication for a lot of switches without dedicated HSR offload.

- Add uAPI defines for 1.6Tbps link modes.

Device drivers:

- Add Motorcomm YT921x gigabit Ethernet switch support.

- Add MUCSE driver for N500/N210 1GbE NIC series.

- Convert drivers to support dedicated ops for timestamping control,
and away from the direct IOCTL handling. While at it support GET
operations for PHY timestamping.

- Add (and convert most drivers to) a dedicated ethtool callback for
reading the Rx ring count.

- Significant refactoring efforts in the STMMAC driver, which
supports Synopsys turn-key MAC IP integrated into a ton of SoCs.

- Ethernet high-speed NICs:
- Broadcom (bnxt):
- support PPS in/out on all pins
- Intel (100G, ice, idpf):
- ice: implement standard ethtool and timestamping stats
- i40e: support setting the max number of MAC addresses per VF

Merge patch series "can: netlink: add CAN XL support"

Marc Kleine-Budde <mkl@pengutronix.de> says:

Similarly to how CAN FD reuses the bittiming logic of Classical CAN, CAN XL
also reuses the entirety of CAN FD features, and, on top of that, adds new
features which are specific to CAN XL.

A so-called 'mixed-mode' is intended to have (XL-tolerant) CAN FD nodes and
CAN XL nodes on one CAN segment, where the FD-controllers can talk CC/FD
and the XL-controllers can talk CC/FD/XL. This mixed-mode utilizes the
known error-signalling (ES) for sending CC/FD/XL frames. For CAN FD and CAN
XL the tranceiver delay compensation (TDC) is supported to use common CAN
and CAN-SIG transceivers.

The CANXL-only mode disables the error-signalling in the CAN XL controller.
This mode does not allow CC/FD frames to be sent but additionally offers a
CAN XL transceiver mode switching (TMS) to send CAN XL frames with up to
20Mbit/s data rate. The TMS utilizes a PWM configuration which is added to
the netlink interface.

Configured with CAN_CTRLMODE_FD and CAN_CTRLMODE_XL this leads to:

FD=0 XL=0 CC-only mode (ES=1)
FD=1 XL=0 FD/CC mixed-mode (ES=1)
FD=1 XL=1 XL/FD/CC mixed-mode (ES=1)
FD=0 XL=1 XL-only mode (ES=0, TMS optional)

Patch #1 print defined ctrlmode strings capitalized to increase the
readability and to be in line with the 'ip' tool (iproute2).

Patch #2 is a small clean-up which makes can_calc_bittiming() use
NL_SET_ERR_MSG() instead of netdev_err().

Patch #3 adds a check in can_dev_dropped_skb() to drop CAN FD frames
when CAN FD is turned off.

Patch #4 adds CAN_CTRLMODE_RESTRICTED. Note that contrary to the other
CAN_CTRL_MODE_XL_* that are introduced in the later patches, this control
mode is not specific to CAN XL. The nuance is that because this restricted
mode was only added in ISO 11898-1:2024, it is made mandatory for CAN XL
devices but optional for other protocols. This is why this patch is added
as a preparation before introducing the core CAN XL logic.

Patch #5 adds all the CAN XL features which are inherited from CAN FD: the
nominal bittiming, the data bittiming and the TDC.

Patch #6 add a new CAN_CTRLMODE_XL_TMS control mode which is specific to
CAN XL to enable the transceiver mode switching (TMS) in XL-only mode.

Patch #7 adds a check in can_dev_dropped_skb() to drop CAN CC/FD frames
when the CAN XL controller is in CAN XL-only mode. The introduced
can_dev_in_xl_only_mode() function also determines the error-signalling
configuration for the CAN XL controllers.

Patch #8 to #11 add the PWM logic for the CAN XL TMS mode.

Patch #12 to #14 add different default sample-points for standard CAN and
CAN SIG transceivers (with TDC) and CAN XL transceivers using PWM in the
CAN XL TMS mode.

Patch #15 add a dummy_can driver for netlink testing and debugging.

Patch #16 check CAN frame type (CC/FD/XL) when writing those frames to the
CAN_RAW socket and reject them if it's not supported by the CAN interface.

Patch #17 increase the resolution when printing the bitrate error and
round-up the value to 0.01% in the case the resolution would still provide
values which would lead to 0.00%.

can: add dummy_can driver

During the development of CAN XL, we found the need of creating a
dummy CAN XL driver in order to test the new netlink interface. While
this code was initially intended to be some throwaway, it received
some positive feedback.

Add the dummy_can driver. This driver acts similarly to the vcan
interface in the sense that it will echo back any packet it receives.
The difference is that it exposes a set on bittiming parameters as a
real device would and thus must be configured as if it was a real
physical interface.

The driver comes with a debug mode. If debug message are enabled (for
example by enabling CONFIG_CAN_DEBUG_DEVICES), it will print in the
kernel log all the bittiming values, similar to what a:

ip --details link show can0

would do.

This driver is mostly intended for debugging and testing, but some
developers also may want to look at it as a simple reference
implementation.
