ff96922d33 dt-bindings: thermal: convert st,stih407-thermal to DT schema
'st,passive_colling_temp' does not appear in the device-tree, 'reg' and
'#thermal-sensor-cells' are also missing in the device description.

Convert st,stih407-thermal binding to DT schema format in order to clean
unused 'st,passive_cooling_temp' and add missing properties.

====================
net: stmmac: Fix MAC-capabilities procedure

The series got born as a result of the discussions around the recent
Yanteng' series adding the Loongson LS7A1000, LS2K1000, LS7A2000, LS2K2000
MACs support:
Link: https://lore.kernel.org/netdev/fu3f6uoakylnb6eijllakeu5i4okcyqq7sfafhp5efaocbsrwe@w74xe7gb6x7p

In particular the Yanteng' patchset needed to implement the Loongson
MAC-specific constraints applied to the link speed and link duplex mode.
As a result of the discussion with Russel the next preliminary patch was
born:
Link: https://lore.kernel.org/netdev/df31e8bcf74b3b4ddb7ddf5a1c371390f16a2ad5.1712917541.git.siyanteng@loongson.cn

The patch above was a temporal solution utilized by Yanteng for further
developments and to move on with the on-going review. This patchset is a
refactored version of that single patch with formatting required for the
fixes patches.

The main part of the series has already been merged in on v1 stage. The
leftover is the cleanup patches which rename
stmmac_ops::phylink_get_caps() callback to stmmac_ops::update_caps() and
move the MAC-capabilities init/re-init to the phylink MAC-capabilities
getter.

Changelog v2:

f951a64922 net: stmmac: Move MAC caps init to phylink MAC caps getter
After a set of recent fixes the stmmac_phy_setup() and
stmmac_reinit_queues() methods have turned to having some duplicated code.
Let's get rid from the duplication by moving the MAC-capabilities
initialization to the PHYLINK MAC-capabilities getter. The getter is
called during each network device interface open/close cycle. So the
MAC-capabilities will be initialized in generic device open procedure and
in case of the Tx/Rx queues re-initialization as the original code
semantics implies.

soc: mediatek: mtk-cmdq: Add cmdq_pkt_acquire_event() function
Add cmdq_pkt_acquire_event() function to support CMDQ user making
an instruction for acquiring event.

CMDQ users can use cmdq_pkt_acquire_event() as `mutex_lock`
and cmdq_pkt_clear_event() as `mutex_unlock` to protect the global
resource modified instructions between them.

cmdq_pkt_acquire_event() would wait for event to be cleared.
After event is cleared by cmdq_pkt_clear_event() in other GCE threads,
cmdq_pkt_acquire_event() would set event and keep executing next
instruction. So the mutex would work like this:

    cmdq_pkt_acquire_event() /* mutex lock */

    /* critical secton instructions that modified global resource */

    cmdq_pkt_clear_event() /* mutex unlock */

Prevent the critical section instructions from being affected by other
GCE threads.

POLL is a legacy operation in GCE, so it does not support SPR and

Chintan Vankar says:

====================
Enable RX HW timestamp for PTP packets using CPTS FIFO

The CPSW offers two mechanisms for communicating packet ingress timestamp
information to the host.

The first mechanism is via the CPTS Event FIFO which records timestamp
when triggered by certain events. One such event is the reception of an
Ethernet packet with a specified EtherType field. This is used to capture
ingress timestamps for PTP packets. With this mechanism the host must
read the timestamp (from the CPTS FIFO) separately from the packet payload
which is delivered via DMA.

In the second mechanism of timestamping, CPSW driver enables hardware
timestamping for all received packets by setting the TSTAMP_EN bit in
CPTS_CONTROL register, which directs the CPTS module to timestamp all
received packets, followed by passing timestamp via DMA descriptors.
This mechanism is responsible for triggering errata i2401:
"CPSW: Host Timestamps Cause CPSW Port to Lock up."

The errata affects all K3 SoCs. Link to errata for AM64x:
https://www.ti.com/lit/er/sprz457h/sprz457h.pdf

As a workaround we can use first mechanism to timestamp received
packets.

c03a6fd398 net: ethernet: ti: am65-cpsw/ethtool: Enable RX HW timestamp only for PTP packets
In the current mechanism of timestamping, am65-cpsw-nuss driver
enables hardware timestamping for all received packets by setting
the TSTAMP_EN bit in CPTS_CONTROL register, which directs the CPTS
module to timestamp all received packets, followed by passing
timestamp via DMA descriptors. This mechanism causes CPSW Port to
Lock up.

To prevent port lock up, don't enable rx packet timestamping by
setting TSTAMP_EN bit in CPTS_CONTROL register. The workaround for
timestamping received packets is to utilize the CPTS Event FIFO
that records timestamps corresponding to certain events. The CPTS
module is configured to generate timestamps for Multicast Ethernet,
UDP/IPv4 and UDP/IPv6 PTP packets.

Update supported hwtstamp_rx_filters values for CPSW's timestamping
capability.

8d5f4da8d7 wifi: ath12k: support suspend/resume
Now that all infrastructure is in place and ath12k is fixed to handle all the
corner cases, power down the ath12k firmware during suspend and power it back
up during resume.

For suspend, two conditions needs to be satisfied:

1. since MHI channel unprepare would be done in late suspend stage,
   ath12k needs to get all QMI-dependent things done before that stage.
2. and because unprepare MHI channels requires a working MHI stack,
   ath12k is not allowed to call mhi_power_down() until that finishes.

So the original suspend callback is separated into two parts: the first part
handles all QMI-dependent things in suspend callback; while the second part
powers down MHI in suspend_late callback. This is valid because kernel calls
ath12k's suspend callback before calling all suspend_late callbacks, making
the first condition satisfied. And because MHI devices are children of ath12k
device (ab->dev), kernel guarantees that ath12k's suspend_late callback is
called after QRTR's suspend_late callback, this satisfies the second condition.

Above analysis also applies to resume process. so the original resume
callback is separated into two parts: the first part powers up MHI stack
in resume_early callback, this guarantees MHI stack is working when
QRTR tries to prepare MHI channels (kernel calls QRTR's resume_early callback
after ath12k's resume_early callback, due to the child-father relationship);
the second part waits for the completion of restart, which would succeed
since MHI channels are ready for use by QMI.

Another notable change is in power down path, we tell mhi_power_down() to not
to destroy MHI devices, making it possible for QRTR to help unprepare/prepare
MHI channels, and finally get us rid of the potential probe-defer issue when
resume.

Also change related code due to interface changes.

2652f6b472 wifi: ath12k: avoid stopping mac80211 queues in ath12k_core_restart()
Currently when resume ath12k_core_restart() calls
ath12k_core_pre_reconfigure_recovery() where mac80211 queues are
stopped by calling ieee80211_stop_queues(). Then in
ath12k_mac_op_reconfig_complete() those queues are not started
because ieee80211_wake_queues() is skipped due to the check on
reconfig_type. The result is that mac80211
could not deliver any frame to ath12k to send out, finally making
connection fail.

Actually we don't need to stop/start queues during suspend/resume,
so remove ath12k_core_pre_reconfigure_recovery() from ath12k_core_restart().
This won't cause any regression because currently the only chance
ath12k_core_restart() gets called is in reset case, where ab->is_reset
is set so that function will never be executed.

Also remove ath12k_core_post_reconfigure_recovery() because it is
not needed in suspend/resume case. This is also valid due to above
analysis.

b1c9992c67 wifi: ath12k: no need to handle pktlog during suspend/resume
Currently pktlog is stopped in suspend callback and started in
resume callback, and in either scenarios it's basically to
delete/modify ab->mon_reap_timer and to purge related rings.
For WCN7850 it's pointless because pktlog is not enabled: both
ab->mon_reap_timer and those rings are not initialized.

So remove pktlog handling in suspend/resume callbacks. And
further, remove these two functions and related callee because
no one is calling them.

Other chips are not affected because now only WCN7850 supports
suspend/resume.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
