Now that the mtk-cmdq.h header contains inline functions for cases
in which the driver is not enabled (either module or built-in), we
can safely go on with cleaning up ifdefs for CMDQ handling.
This also shows in a clearer manner that writing through CMDQ HW is
optional and used only for performance purposes when/where wanted,
needed and/or required.

This patch fixes a corner case where the asoc out stream count may change
after wait_for_sndbuf.
When the main thread in the client starts a connection, if its out stream
count is set to N while the in stream count in the server is set to N - 2,
another thread in the client keeps sending the msgs with stream number
N - 1, and waits for sndbuf before processing INIT_ACK.
However, after processing INIT_ACK, the out stream count in the client is
shrunk to N - 2, the same to the in stream count in the server. The crash
occurs when the thread waiting for sndbuf is awake and sends the msg in a
non-existing stream(N - 1), the call trace is as below:

The driver registers a thermal zone for each transceiver module and
tries to set the trip point temperatures according to the thresholds
read from the transceiver. If a threshold cannot be read or if a
transceiver is unplugged, the trip point temperature is set to zero,
which means that it is disabled as far as the thermal subsystem is
concerned.
A recent change in the thermal core made it so that such trip points are
no longer marked as disabled, which lead the thermal subsystem to
incorrectly set the associated cooling devices to the their maximum
state [1]. A fix to restore this behavior was merged in commit
f1b80a3878 ("thermal: core: Restore behavior regarding invalid trip
points"). However, the thermal maintainer suggested to not rely on this
behavior and instead always register a valid array of trip points [2].
Therefore, create a static array of trip points with sane defaults
(suggested by Vadim) and register it with the thermal zone of each
transceiver module. User space can choose to override these defaults
using the thermal zone sysfs interface since these files are writeable.
Before:
$ cat /sys/class/thermal/thermal_zone11/type
mlxsw-module11
$ cat /sys/class/thermal/thermal_zone11/trip_point_*_temp
65000
75000
80000
After:
$ cat /sys/class/thermal/thermal_zone11/type
mlxsw-module11
$ cat /sys/class/thermal/thermal_zone11/trip_point_*_temp
55000
65000
80000
Also tested by reverting commit f1b80a3878 ("thermal: core: Restore
behavior regarding invalid trip points") and making sure that the
associated cooling devices are not set to their maximum state.

Based on further tests, it seems that the QDMA shaper is not able to
perform shaping close to the MAC link rate without throughput loss.
This cannot be compensated by increasing the shaping rate, so it seems
to be an internal limit.
Fix the remaining throughput regression by detecting that condition and
limiting shaping to ports with lower link speed.
This patch intentionally ignores link speed gain from TRGMII, because
even on such links, shaping to 1000 Mbit/s incurs some throughput
degradation.

Commit 0db3dc73f7 ("[NETPOLL]: tx lock deadlock fix") narrowed
down the region under netif_tx_trylock() inside netpoll_send_skb().
(At that point in time netif_tx_trylock() would lock all queues of
the device.) Taking the tx lock was problematic because driver's
cleanup method may take the same lock. So the change made us hold
the xmit lock only around xmit, and expected the driver to take
care of locking within ->ndo_poll_controller().
Unfortunately this only works if netpoll isn't itself called with
the xmit lock already held. Netpoll code is careful and uses
trylock(). The drivers, however, may be using plain lock().
Printing while holding the xmit lock is going to result in rare
deadlocks.
Luckily we record the xmit lock owners, so we can scan all the queues,
the same way we scan NAPI owners. If any of the xmit locks is held
by the local CPU we better not attempt any polling.
It would be nice if we could narrow down the check to only the NAPIs
and the queue we're trying to use. I don't see a way to do that now.

* input_test_match_device_id: match a device by bus, vendor, product,

x86 ACPI boards which ship with only Android as their factory image may
have pretty broken ACPI tables. This includes broken _AEI ACPI GPIO event
handlers, which are normally used to listen to the micro-USB ID pin and:
1. Switch the USB-mux to the host / device USB controllers
2. Disable Vbus path before enabling the 5V boost (AXP reg 0x30 bit 7)
3. Turn 5V Vboost on / off
On non broken systems where this is not done through an ACPI GPIO event
handler, there is an ACPI INT3496 device describing the involved GPIOs
which are handled by the extcon-intel-int3496 driver; and axp288-charger.ko
listens to this extcon-device and disables the Vbus path when necessary.
On x86 Android boards, with broken ACPI GPIO event handlers, these are
disabled by acpi_quirk_skip_gpio_event_handlers() and an intel-int3496
extcon device is manually instantiated by x86-android-tablets.ko .
Add support to the axp288-charger code for this setup, so that it
properly disables the Vbus path when necessary. Note this uses
acpi_quirk_skip_gpio_event_handlers() to identify these systems,
to avoid the need to add a separate DMI match table for this.

Merge v6.3-rc3, so that 'acpi_quirk_skip_gpio_event_handlers'
is available, which is needed for adding x86 android tablet
support in axp288_charger.

Currently the TI thermal driver sets the sensor update interval based
on the polling of the thermal zone. In order to get the polling rate,
the code inspects the thermal zone device structure internals, thus
breaking the self-encapsulation of the thermal framework core
framework.
On the other side, we see the common polling rates set in the device
tree for the platforms using this driver are 500 or 1000 ms.
Setting the polling rate to 250 ms would be far enough to cover the
combination we found in the device tree.
Instead of accessing the thermal zone device structure polling rate,
let's use a common update interval of 250 ms for the driver.

The thermal->tzp->no_hwmon parameter is only used when calling
thermal_zone_device_register().
Setting it to 'false' before calling thermal_add_hwmon_sysfs() has no
effect.
Remove the call and again prevent the drivers to access the thermal
internals.

The db8500 driver uses the thermal zone device instead of the device
attached to it. In order to prevent the drivers to access the thermal
zone device structure, replace the thermal zone device by the driver
to show the debug message.
