Fix 3 typos in 8703b driver. 2 typos in calibration routines are not
fatal and do not seem to have any impact, just fix them to match vendor
driver.
However the last one in rtw8703b_set_channel_bb() clears too many bits
in REG_OFDM0_TX_PSD_NOISE, causing TX and RX issues (neither rate goes
above MCS0-MCS1). Vendor driver clears only 2 most significant bits.
With the last typo fixed, the driver is able to reach MCS7 on Pinebook

Add some extra configuration for USB devices. Currently only RTL8822BU
version (cut) D needs this. The new code makes use of the existing
usb3_param_8822b array from rtw8822b.c.
A user reported that TP-Link Archer T3U in USB 3 mode was randomly
disconnecting from USB:

The rtwdev->scanning flag isn't protected by mutex originally, so
cancel_hw_scan can pass the condition, but suddenly hw_scan completion
unset the flag and calls ieee80211_scan_completed() that will free
local->hw_scan_req. Then, cancel_hw_scan raises null-ptr-deref and
use-after-free. Fix it by moving the check condition to where
protected by mutex.

For each MCC role, time limits, including max_tob_us, max_toa_us, and
mac_dur_us, are calculated if there are NoA attributes. The relation
between these time limits is "max_dur_us = max_tob_us + max_toa_us".
Then, the unit is converted from us to TU. However, originally, each
time limit was divided by 1024 independently. It missed to consider
the cases that max_tob_us or max_toa_us is not divisible by 1024. It
causes the result breaks "max_dur (TU) = max_tob (TU) + max_toa (TU)".
Finally, when MCC calculates pattern parameters based on these kinds
of time limits, it might not perform well.

For early chips, the RX BD info contains FS/LS bits for first/last segments
of a receiving packet. For 8922AE, the FS bit should be ignored, or it
may throw warning:
rtw89_8922ae 0000:1a:00.0: skb should not be ready before first segment start
To have compatible logic, FS determined by what pending skb is existing
(!new) or not.
Since we expect every single receiving packet in single one segment,
enlarge 4 bytes for RX BD info, and add a debug message to note if
RX buffer is possibly smaller than expected size.

If WoWLAN failed in resume flow, the rtw89_ops_add_interface() triggered
without removing the interface first. Then the mgnt_entry list init again,
causing the list_empty() check in rtw89_chanctx_ops_assign_vif()
useless, and list_add_tail() again. Therefore, we have added a check to
prevent double adding of the list.

During rtw89_entity_recalc_mgnt_roles(), there is a normalizing process
which will re-order the list if an entry with target pattern is found.
And once one is found, should have aborted the list_for_each_entry. But,
`break` just aborted the inner for-loop. The outer list_for_each_entry
still continues. Normally, only the first entry will match the target
pattern, and the re-ordering will change nothing, so there won't be
soft lockup. However, in some special cases, soft lockup would happen.
Fix it by `goto fill` to break from the list_for_each_entry.
The following is a sample of kernel log for this problem.

When starting/proceeding MCC, it will abort an ongoing hw scan process.
In the proceeding cases, it unexpectedly tries to abort a non-exist hw
scan process. Then, a trace shown at the bottom will happen. This problem
is caused by a previous commit which changed some call sequence inside
rtw89_hw_scan_complete() to fix some coex problems. These changes lead
to our scanning flag was not cleared when proceeding MCC. To keep the
fixes on coex, and resolve the problem here, re-consider the related
call sequence.
The known sequence requirements are listed below.
* the old sequence:
A. notify coex
B. clear scanning flag
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
(the problem: A needs to be after C-1)
* the current sequence:
C. proceed chanctx
C-1. set channel
C-2. proceed MCC
A. notify coex
B. clear scanning flag
(the problem: C-2 needs to be after B)
So, now let hw scan caller pass a callback to proceed chanctx if needed.
Then, the new sequence will be like the below.
C-1. set channel
A. notify coex
B. clear scanning flag
C-2. proceed MCC
The following is the kernel log for the problem in current sequence.

The DP83822 supports up to three configurable Light Emitting Diode (LED)
pins: LED_0, LED_1 (GPIO1), COL (GPIO2) and RX_D3 (GPIO3). Several
functions can be multiplexed onto the LEDs for different modes of
operation. LED_0 and COL (GPIO2) use the MLED function. MLED can be routed
to only one of these two pins at a time. Add minimal LED controller driver
supporting the most common uses with the 'netdev' trigger.

====================
pull-request: can-next 2025-01-10
Pierre-Henry Moussay adds PIC64GX compatibility to the DT bindings for
Microchip's mpfs-can IP core.
The next 3 patches are by Sean Nyekjaer and target the tcan4x5x
driver. First the DT bindings is converted to DT schema, then nWKRQ
voltage selection is added to the driver.
Dario Binacchi's patch for the sun4i_can makes the driver more
consistent by adding a likely() to the driver.
Another patch by Sean Nyekjaer for the tcan4x5x driver gets rid of a
false error message.
Charan Pedumuru converts the atmel-can DT bindings to DT schema.
The next 2 patches are by Oliver Hartkopp. The first one maps Oliver's
former mail addresses to a dedicated CAN mail address. The second one
assigns net/sched/em_canid.c additionally to the CAN maintainers.
Ariel Otilibili's patch removes dead code from the CAN dev helper.
The next 3 patches are by Sean Nyekjaer and add HW standby support to
the tcan4x5x driver.
A patch by Dario Binacchi fixes the DT bindings for the st,stm32-bxcan
driver.
The last 4 patches are by Jimmy Assarsson and target the kvaser_usb
and the kvaser_pciefd driver: error statistics are improved and
CAN_CTRLMODE_BERR_REPORTING is added.

In all 3 cases (cpsw, cpsw-new, am65-cpsw) ALE is being configured in
VLAN-aware mode, while the comment states the opposite. Seems to be a typo
copy-pasted from one driver to another. Fix the commend which has been
puzzling some people (including me) for at least a decade.

When tx_max_frame_size was added to struct ravb_hw_info, no value was
set in ravb_rzv2m_hw_info so the default value of zero was used.
The maximum MTU is set by subtracting from tx_max_frame_size to allow
space for headers and frame checksums. As ndev->max_mtu is unsigned,
this subtraction wraps around leading to a ridiculously large positive
value that is obviously incorrect.
Before tx_max_frame_size was introduced, the maximum MTU was based on
rx_max_frame_size. So, we can restore the correct maximum MTU by copying
the rx_max_frame_size value into tx_max_frame_size for RZ/V2M.

Due to this, when mana driver is configured as a module and rmmod is
invoked, following stack gets printed along with failure in rmmod command.

Recalculate features when XDP is detached.
Before:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: off [requested on]
After:
# ip li set dev eth0 xdp obj xdp_dummy.bpf.o sec xdp
# ip li set dev eth0 xdp off
# ethtool -k eth0 | grep gro
rx-gro-hw: on
The fact that HW-GRO doesn't get re-enabled automatically is just
a minor annoyance. The real issue is that the features will randomly
come back during another reconfiguration which just happens to invoke
netdev_update_features(). The driver doesn't handle reconfiguring
two things at a time very robustly.
Starting with commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in
__bnxt_reserve_rings()") we only reconfigure the RSS hash table
if the "effective" number of Rx rings has changed. If HW-GRO is
enabled "effective" number of rings is 2x what user sees.
So if we are in the bad state, with HW-GRO re-enablement "pending"
after XDP off, and we lower the rings by / 2 - the HW-GRO rings
doing 2x and the ethtool -L doing / 2 may cancel each other out,
and the:
if (old_rx_rings != bp->hw_resc.resv_rx_rings &&
condition in __bnxt_reserve_rings() will be false.
The RSS map won't get updated, and we'll crash with:

The issue is present since XDP support was added, really, but
prior to commit 98ba1d931f61 ("bnxt_en: Fix RSS logic in

phylink_stop() will cause phylink to call the mac_link_down() operation
before phylink_stop() returns. As mac_link_down() will call
stmmac_eee_init(false), this will set both priv->eee_active and
priv->eee_enabled to be false, deleting the eee_ctrl_timer if
priv->eee_enabled was previously set.
As stmmac_release() calls phylink_stop() before checking whether
priv->eee_enabled is true, this is a condition that can never be
satisfied, and thus the code within this if() block will never be
executed. Remove it.

All call sites for stmmac_eee_init() assign the return code to
priv->eee_enabled. Rather than having this coded at each call site,
move the assignment inside stmmac_eee_init().
Since stmmac_init_eee() takes priv->lock before checking the state of
priv->eee_enabled, move the assignment within the locked region. Also,
stmmac_suspend() checks the state of this member under the lock. While
two concurrent calls to stmmac_init_eee() aren't possible, there is
a possibility that stmmac_suspend() may run concurrently with a change
of priv->eee_enabled unless we modify it under the lock.

priv->eee_tw_timer is only assigned during initialisation to a
constant value (STMMAC_DEFAULT_TWT_LS) and then never changed.
Remove priv->eee_tw_timer, and instead use STMMAC_DEFAULT_TWT_LS
for both uses in stmmac_eee_init().

stmmac_disable_eee_mode() is now only called from stmmac_xmit() when
both priv->tx_path_in_lpi_mode and priv->eee_sw_timer_en are true.
Therefore:
if (!priv->eee_sw_timer_en)
in stmmac_disable_eee_mode() will never be true, so this is dead code.
Remove it, and rename the function to indicate that it now only deals
with software based EEE mode.

Setting edata->tx_lpi_enabled in stmmac_ethtool_op_get_eee() gets
overwritten by phylib, so there's no point setting this.
In stmmac_ethtool_op_set_eee(), now that stmmac is using the result of
phylib's evaluation of EEE, there is no need to handle anything in the
ethtool EEE ops other than calling through to the appropriate phylink
function, which will pass on to phylib the users request.
As stmmac_disable_eee_mode() is now no longer called from outside
stmmac_main.c, make it static.

Make stmmac EEE depend on phylib's evaluation of user settings and PHY
negotiation, as indicated by phy->enable_tx_lpi. This will ensure when
phylib has evaluated that the user has disabled LPI, phy_init_eee()
will not be called, and priv->eee_active will be false, causing LPI/EEE
to be disabled.
This is an interim measure - phy_init_eee() will be removed in a later
patch.

Since eee_timer is used to initialise priv->tx_lpi_timer, this also
should be unsigned to avoid a negative number being interpreted as a
very large positive number. Note that this makes the check for negative
numbers passed in as a module parameter redundant, and passing a
negative number will now produce a large delay rather than the
default. Since the default is used without an argument, passing a
negative number would be quite obscure. However, if users do, then
this will need to be revisited.

The ethtool interface uses u32 for tx_lpi_timer, and so does phylib.
Use u32 to store this internally within stmmac rather than "int"
which could misinterpret large values.
Correct "value" in dwmac4_set_eee_lpi_entry_timer() to use u32
rather than int, which is derived from tx_lpi_timer. Even though this
path won't be used with values larger than STMMAC_ET_MAX, this brings
consistency of type usage to the stmmac code for this variable.
We leave eee_timer unchanged for now, with the assumption that values
up to INT_MAX will safely fit in a u32.

When stmmac_ethtool_op_get_eee() is called, stmmac sets the tx_lpi_timer
and tx_lpi_enabled members, and then calls into phylink and thus phylib.
phylib overwrites these members.
phylib will also cause a link down/link up transition when settings
that impact the MAC have been changed.
Convert stmmac to use the tx_lpi_timer setting in struct phy_device,
updating priv->tx_lpi_timer each time when the link comes up, rather
than trying to maintain this user setting itself. We initialise the
phylib tx_lpi_timer setting by doing a get_ee-modify-set_eee sequence
with the last known priv->tx_lpi_timer value. In order for this to work
correctly, we also need this member to be initialised earlier.
As stmmac_eee_init() is no longer called outside of stmmac_main.c, make
it static.

Add support to request transmit rate buffer stats from firmware through
HTT stats type 31. These stats give information such as MCS, NSS and
bandwidth of transmit and input buffer.
Sample output:
-------------
echo 31 > /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats_type
cat /sys/kernel/debug/ath12k/pci-0000\:06\:00.0/mac0/htt_stats

Pull RISC-V fixes from Palmer Dabbelt:
- a handful of selftest fixes
- fix a memory leak in relocation processing during module loading
- avoid sleeping in die()
- fix kprobe instruction slot address calculations
- fix DT node reference leak in SBI idle probing
- avoid initializing out of bounds pages on sparse vmemmap systems with
a gap at the start of their physical memory map
- fix backtracing through exceptions
- _Q_PENDING_LOOPS is now defined whenever QUEUED_SPINLOCKS=y
- local labels in entry.S are now marked with ".L", which prevents them
from trashing backtraces
- a handful of fixes for SBI-based performance counters

Pull gpio fixes from Bartosz Golaszewski:
"There's one small fix for real HW - gpio-loongson.
The rest concern two virtual testing drivers in which some issues were
recently found and addressed:
- fix resource leaks in error path in gpio-virtuser (and one
consistent memory leak triggered on every device removal))
- fix the use-case of having multiple con_ids in a lookup table in
gpio-virtuser which has never worked (despite being advertised)
- don't allow rmdir() on configfs directories when they are in use in
gpio-sim and gpio-virtuser
- fix register offsets in gpio-loongson-64"
