Pull vfs superblock updates from Christian Brauner:
"This contains the work to make block device opening functions return a
struct bdev_handle instead of just a struct block_device. The same
struct bdev_handle is then also passed to block device closing
functions.
This allows us to propagate context from opening to closing a block
device without having to modify all users everytime.
Sidenote, in the future we might even want to try and have block
device opening functions return a struct file directly but that's a
series on top of this.
These are further preparatory changes to be able to count writable
opens and blocking writes to mounted block devices. That's a separate
piece of work for next cycle and for that we absolutely need the
changes to btrfs that have been quietly dropped somehow.
Originally the series contained a patch that removed the old
blkdev_*() helpers. But since this would've caused needles churn in
-next for bcachefs we ended up delaying it.
The second piece of work addresses one of the major annoyances about
the work last cycle, namely that we required dropping s_umount
whenever we used the superblock and fs_holder_ops for a block device.
The reason for that requirement had been that in some codepaths
s_umount could've been taken under disk->open_mutex (that's always
been the case, at least theoretically). For example, on surprise block
device removal or media change. And opening and closing block devices
required grabbing disk->open_mutex as well.
So we did the work and went through the block layer and fixed all
those places so that s_umount is never taken under disk->open_mutex.
This means no more brittle games where we yield and reacquire s_umount
during block device opening and closing and no more requirements where
block devices need to be closed. Filesystems don't need to care about
this.
There's a bunch of other follow-up work such as moving block device
freezing and thawing to holder operations which makes it work for all
block devices and not just the main block device just as we did for
surprise removal. But that is for next cycle.
Tested with fstests for all major fses, blktests, LTP"

MPS Flow
Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer High Flow USB flow sensor, which communicates through a
proprietary USB HID protocol. This commit also adds support for the sensors
of the MPS Flow devices, as they have the same USB product ID and sensor
layouts. Implemented by Leonard Anderweit [1].
Internal and external temp sensor readings are available, along with
the flow sensor.
Additionally, serial number and firmware version are exposed through
debugfs.

Add support for LTC2991 Octal I2C Voltage, Current, and Temperature
Monitor.
The LTC2991 is used to monitor system temperatures, voltages and
currents. Through the I2C serial interface, the eight monitors can
individually measure supply voltages and can be paired for
differential measurements of current sense resistors or temperature
sensing transistors. Additional measurements include internal
temperature and internal VCC.

The MAX31785 has shown erratic behaviour across multiple system
designs, unexpectedly clock stretching and NAKing transactions.
Experimentation shows that this seems to be triggered by a register access
directly back to back with a previous register write. Experimentation also
shows that inserting a small delay after register writes makes the issue go
away.
Use a similar solution to what the max15301 driver does to solve the same
problem. Create a custom set of bus read and write functions that make sure
that the delay is added.

The INA237 "85-V, 16-Bit, Precision Power Monitor With I2C Interface" is
basically the same as INA328. Therefore add a corresponding compatible
to the driver.
According to the datasheet the main difference is the current and power
monitoring accuracy:
+------------------------+---------------+---------------+
| | INA238 | INA237 |
+------------------------+---------------+---------------+
| Offset voltage | +/- 5µV | +/- 50µV |
| Offset drift | +/- 0.02µV/°C | +/- 0.02µV/°C |
| Gain error | +/- 0.1% | +/- 0.3% |
| Gain error drift | +/- 25ppm/°C | +/- 50ppm/°C |
| Common mode rejection | 140dB | 120dB |
| Power accuracy | 0.7% | 1.6% |
+------------------------+---------------+---------------+
As well as the missing DEVICE_ID register at 0x3F, which is currently
not in use by the driver.

The INA3221 allows the Critical alert pin to be controlled by the
summation control function. This function adds the single
shunt-voltage conversions for the desired channels in order to compare
the combined sum to the programmed limit. The Shunt-Voltage Sum Limit
register contains the programmed value that is compared to the value in
the Shunt-Voltage Sum register in order to determine if the total summed
limit is exceeded. If the shunt-voltage sum limit value is exceeded, the
Critical alert pin pulls low.
For the summation limit to have a meaningful value, we have to use the
same shunt-resistor value on all included channels. Unless equal
shunt-resistor values are used for each channel, the summation control
function cannot be used and it is not enabled by the driver.
To address this, add support to disable the summation of specific
channels via device tree property "ti,summation-disable". The channel
which has this property would be excluded from the calculation of
summation control function.
For example, summation control function calculates Shunt-Voltage Sum as:
- input_shunt_voltage_summation = input_shunt_voltage_channel1
+ input_shunt_voltage_channel2
+ input_shunt_voltage_channel3
If we want the summation to only use channel1 and channel3, we can add
'ti,summation-disable' property in device tree node for channel2. Then
the calculation will skip channel2.
- input_shunt_voltage_summation = input_shunt_voltage_channel1
+ input_shunt_voltage_channel3
Note that we only want the channel to be skipped for summation control
function rather than completely disabled. Therefore, even if we add the
property 'ti,summation-disable', the channel is still enabled and
functional.
Finally, create debugfs entries that display if summation is disabled
for each of the channels.

disk_check_media_change is mostly called from ->open where it makes
little sense to mark the file system on the device as dead, as we
are just opening it. So instead of calling bdev_mark_dead from
disk_check_media_change move it into the few callers that are not
in an open instance. This avoid calling into bdev_mark_dead and
thus taking s_umount with open_mutex held.

Coverity has noticed that the printing of error message in
register_cache() uses already freed bdev_handle to get to bdev. In fact
the problem has been there even before commit "bcache: Convert to
bdev_open_by_path()" just a bit more subtle one - cache object itself
could have been freed by the time we looked at ca->bdev and we don't
hold any reference to bdev either so even that could in principle go
away (due to device unplug or similar). Fix all these problems by
printing the error message before closing the bdev.

Both cros host command and irq disable were moved to suspend
prepare stage from late suspend recently. This is causing EC
to report MKBP event timeouts during suspend stress testing.
When the MKBP event timeouts happen during suspend, subsequent
wakeup of AP by EC using MKBP doesn't happen properly. Move the
irq disabling part back to late suspend stage which is a general
suggestion from the suspend kernel documentaiton to do irq
disable as late as possible.

Pull clk fixes from Stephen Boyd:
"Three fixes, one for the clk framework and two for clk drivers:
- Avoid an oops in possible_parent_show() by checking for no parent
properly when a DT index based lookup is used
- Handle errors returned from divider_ro_round_rate() in
clk_stm32_composite_determine_rate()
- Fix clk_ops::determine_rate() implementation of socfpga's
gateclk_ops that was ruining uart output because the divider
was forgotten about"

The clk gate kunit test checks that the implementation of the basic clk
gate reads and writes the proper bits in an MMIO register. The
implementation of the basic clk gate type uses writel() and readl()
which operate on little-endian registers. This test fails on big-endian
CPUs because the clk gate implementation writes to 'fake_reg' with
writel(), which converts the value to be written to little-endian before
storing the value in the fake register. When the test checks the bits in
the fake register on a big-endian machine it falsely assumes the format
of the register is also big-endian, when it is really always
little-endian. Suffice to say things don't work very well.
Mark 'fake_reg' as __le32 and push through endian accessor fixes
wherever the value is inspected to make this test endian agnostic.
There's a CLK_GATE_BIG_ENDIAN flag for big-endian MMIO devices, which
this test isn't using. A follow-up patch will test with and without that
flag.

Pull ATA fix from Damien Le Moal:
"A single patch to fix a regression introduced by the recent
suspend/resume fixes.
The regression is that ATA disks are not stopped on system shutdown,
which is not recommended and increases the disks SMART counters for
unclean power off events.
This patch fixes this by refining the recent rework of the scsi device
manage_xxx flags"
