Persistent grants feature provides high scalability. On some small
systems, however, it could incur data copy overheads[1] and thus it is
required to be disabled. It can be disabled from blkback side using a
module parameter, 'feature_persistent'. But, it is impossible from
blkfront side. For the reason, this commit adds a blkfront module
parameter for disabling of the feature.

Currently the sign for CURRENT_NOW and CURRENT_AVG is a bit
of a mess. There are basically 3 different ways battery fuel
gauges report the current:
1. uses negative values for discharging and positive values
for charging
2. uses positive values for discharging and negative values
for discharging (opposit of 1)
3. only uses positive values
As a result userspace currently cannot use the sign at all in
a generic way. Let's solve the issue by documenting a canonical
way for reporting the data and ensure new drivers follow this
way. Then existing drivers can be fixed on a case-by-case basis.
The 'negative value = battery discharging' has been choosen,
since there are only very few drivers doing it the other way
around.

Pull f2fs updates from Jaegeuk Kim:
"In this round, we've added new features such as zone capacity for ZNS
and a new GC policy, ATGC, along with in-memory segment management. In
addition, we could improve the decompression speed significantly by
changing virtual mapping method. Even though we've fixed lots of small
bugs in compression support, I feel that it becomes more stable so
that I could give it a try in production.
Enhancements:
- suport zone capacity in NVMe Zoned Namespace devices
- introduce in-memory current segment management
- add standart casefolding support
- support age threshold based garbage collection
- improve decompression speed by changing virtual mapping method
Bug fixes:
- fix condition checks in some ioctl() such as compression, move_range, etc
- fix 32/64bits support in data structures
- fix memory allocation in zstd decompress
- add some boundary checks to avoid kernel panic on corrupted image
- fix disallowing compression for non-empty file
- fix slab leakage of compressed block writes
In addition, it includes code refactoring for better readability and
minor bug fixes for compression and zoned device support"

There are several issues in current background GC algorithm:
- valid blocks is one of key factors during cost overhead calculation,
so if segment has less valid block, however even its age is young or
it locates hot segment, CB algorithm will still choose the segment as
victim, it's not appropriate.
- GCed data/node will go to existing logs, no matter in-there datas'
update frequency is the same or not, it may mix hot and cold data
again.
- GC alloctor mainly use LFS type segment, it will cost free segment
more quickly.
This patch introduces a new algorithm named age threshold based
garbage collection to solve above issues, there are three steps
mainly:
1. select a source victim:
- set an age threshold, and select candidates beased threshold:
e.g.
0 means youngest, 100 means oldest, if we set age threshold to 80
then select dirty segments which has age in range of [80, 100] as
candiddates;
- set candidate_ratio threshold, and select candidates based the
ratio, so that we can shrink candidates to those oldest segments;
- select target segment with fewest valid blocks in order to
migrate blocks with minimum cost;
2. select a target victim:
- select candidates beased age threshold;
- set candidate_radius threshold, search candidates whose age is
around source victims, searching radius should less than the
radius threshold.
- select target segment with most valid blocks in order to avoid
migrating current target segment.
3. merge valid blocks from source victim into target victim with
SSR alloctor.
Test steps:
- create 160 dirty segments:
* half of them have 128 valid blocks per segment
* left of them have 384 valid blocks per segment
- run background GC
Benefit: GC count and block movement count both decrease obviously:
- Before:
- Valid: 86
- Dirty: 1
- Prefree: 11
- Free: 6001 (6001)
GC calls: 162 (BG: 220)
- data segments : 160 (160)
- node segments : 2 (2)
Try to move 41454 blocks (BG: 41454)
- data blocks : 40960 (40960)
- node blocks : 494 (494)
IPU: 0 blocks
SSR: 0 blocks in 0 segments
LFS: 41364 blocks in 81 segments
- After:
- Valid: 87
- Dirty: 0
- Prefree: 4
- Free: 6008 (6008)
GC calls: 75 (BG: 76)
- data segments : 74 (74)
- node segments : 1 (1)
Try to move 12813 blocks (BG: 12813)
- data blocks : 12544 (12544)
- node blocks : 269 (269)
IPU: 0 blocks
SSR: 12032 blocks in 77 segments
LFS: 855 blocks in 2 segments

Patch here adds a cpumask attr to hv_gpci pmu along with ABI documentation.
Primary use to expose the cpumask is for the perf tool which has the
capability to parse the driver sysfs folder and understand the
cpumask file. Having cpumask file will reduce the number of perf command
line parameters (will avoid "-C" option in the perf tool
command line). It can also notify the user which is
the current cpu used to retrieve the counter data.
command:# cat /sys/devices/hv_gpci/cpumask

GX20MH01 device shares family number 0x28 with DS18B20. The device
is generally compatible with DS18B20. Added are the lowest 2^-5, 2^-6
temperature bits in Config register; R2 bit in Config register
enabling 13 and 14 bit resolutions. It is powered up in 14 bit mode.

The conversion time of common DS18B20 clones deviates from
datasheet specs. Allow adjustment and automatic measure of the
conversion time.
Add 'conv_time' sysfs attribute:
*read*: Current conversion time in milliseconds.
*write*:
'0': Set default conversion time.
'1': Measure and set the conversion time. Make a
single temperature conversion, poll and measure
an actual value. Measured value is increased
by 20% for temperature drift. A new conversion
time is returned by reading the same attribute.
other positive value:
Set the conversion time in milliseconds.
The setting is active until a resolution change. Then it is reset to
default conversion time for a new resolution.
Add 'features' sysfs attribute to control optional driver settings
per device. Bit masks to read/write (logical OR):
1: Enable check for conversion success. If byte 6 of
scratchpad memory is 0xC after conversion, and
temperature reads 85.00 (powerup value) or 127.94
(insufficient power) - return a conversion error.
2: Enable poll for conversion completion. Generate read cycles
after the conversion start and wait for 1's. In parasite
power mode this feature is not available.
There are some clones of DS18B20 with fixed 12 bit resolution. Make the
driver verify the resolution by reading back the device after resolution
change.

Introduce sysfs entries to enable userspace clients the ability to read
the serial number and the OEM PK Hash values obtained from BHI. OEMs
need to read these device-specific hardware information values through
userspace for factory testing purposes and cannot be exposed via degbufs
as it may remain disabled for performance reasons. Also, update the
documentation for ABI to include these entries.

The MIPI DisCo device properties that are read by the driver from
platform firmware, or hard-coded in the driver, should only be
provided as sysfs entries when a driver probes successfully.
However the device status and device number is updated even when there
is no driver present, and hence can be updated when a Slave device is
detected on the bus without being described in platform firmware and
without any driver registered/probed.
As suggested by GregKH, the attribute group for Slave status and
device number is is added by default upon device registration.
Credits to Vinod Koul for the status_show() function, shared in a
separate patch and used as is here. The status table was modified to
remove an unnecessary enum and status_show() is handled in a different
group attribute than what was suggested by Vinod.

ArmCP mandates that the device CPU is always an ARM processor, which might
be wrong in the future.
Most of this change is an internal renaming of variables, functions and
defines but there are two entries in sysfs which have armcp in their
names. Add identical cpucp entries but don't remove yet the armcp entries.
Those will be deprecated next year. Add the documentation about it in sysfs
documentation.

Here is the first set of changes for the 5.10-rc1 merge window.
Xilinx:
- Luca's changes clean up the xilinx-spi driver and add better
diagnostics on errors.
Core:
- I cleaned up a stray comment.
- Richard's change marks FPGA manager tasks un-interruptible.
- Tom has agreed to help out as Reviewer in the FPGA Manager subsystem.
DFL:
- Xu's changes add a new bus that is the first part of a series to support
adding devices via DFL (the other parts are still under review)
All patches have been reviewed on the mailing list, and have been in the
last few linux-next releases (as part of my for-next branch) without issues.

A new bus type "dfl" is introduced for private features which are not
initialized by DFL feature drivers (dfl-fme & dfl-afu drivers). So these
private features could be handled by separate driver modules.
DFL feature drivers (dfl-fme, dfl-port) will create DFL devices on
enumeration. DFL drivers could be registered on this bus to match these
DFL devices. They are matched by dfl type & feature_id.

Systems have a line for restting the remote CFAM. This is not part of
the FSI master, but is associated with it, so it makes sense to include
it in the master driver.
This exposes a sysfs interface to reset the cfam, abstracting away the
direction and polarity of the GPIO, as well as the timing of the reset
pulse. Userspace will be blocked until the reset pulse is finished.
The reset is hard coded to be in the range of (900, 1000) us. It was
observed with a scope to regularly be just over 1ms.
If the device tree property is not preset the driver will silently
continue.

Second set of features and cleanups for IIO in 5.10
We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.
There are a few late breaking fixes in here that can wait for the
merge window.
dt yaml conversions
-------------------
* adi,ad7768-1
* adi,ad7949
* aspeed,ast2400
* cosmic,10001-adc
* dlg,da9150-gpadc

* st,stmpe-adc
* ti,adc12138
* ti,ads1015
* ti,ads7950
* ti,twl4030-madc
Features
--------
* adxrs290
- Add triggered buffer support and expose data ready signal as a possible
trigger. Includes updating bindings.
- Add debugfs hooks for register access.
* mlx90632
- Add a clear user interface to override the measured ambient temperature.
* vl53l0x
- Add IRQ support including dt bindings.
Cleanups and minor fixes
------------------------
(groups)
Replace mlock with local lock:
* adf4350
* exynos-adc
* fls-imx25-gcq
* stm32-dac
devm use to simplify probe error handling and remove functions.
* adis16201
* adis16203
* adis16209
* adis16240
* adis16136
* adis16260
* adis16400
* adis16460
* adis16480
* adis library - drop unused adis_setup_buffer_and_trigger()
of_match_ptr removal and incorrect ACPI binding removal
of_match_ptr() rarely makes sense in an IIO driver as space saving
is trivial and it breaks ACPI PRP0001 based instantiation.
Mostly this series is about removing examples that get copied into new
drivers.
* ad2s1200
* ad5272
* ad5446
* ad5592r
* ad5593r
* ad5703

kernel-doc fixes
* iio-core
* ad7303
* ad7947
* adis16080
* adis16400
* iio_dummy_evgen
* sgp30
Fixes for buffer alignment when passed to iio_push_to_buffers_with_timestamp()
This is a long running effort. There are a few more drivers to come.
* inv_mpu6050
* itg3200
* si1145
* st_lsm6dsx
* ti-adc0832
* ti-adc12138
(not driver focused)
* MAINTAINERS
- Consolidate Analog Device IIO entries whilst removing Beniamin Bia.
- Remove Hartmut Knaack as a listed IIO maintainer as he hasn't been
active for a long time and people are getting intermitted bounces.
* Add __printf() markings to a few functions that were missing them.
* drop some rotted documentation from staging.
* rework buffer sysfs file creation (precursor to multiple buffer support)
(individual drivers)
* ad5592r
- Fix use of true for IIO_SHARED_BY_TYPE
- Tidy up locking and indentation.
* ad9467
- Improve error message on chip-id missmatch.
- Use more appropriate error value if chip-id not recognised.
* adis-library
- Simplify burst mode handling.
* adxrs290
- Make sure to switch device to standby mode during remove.
* as73211
- Increase measurement timeout as seems some devices are slower.

* inv_mpu6050
- Use regmap_noinc_read() for fifo reading.
* palmas_gpadc
- Use module_platform_driver() to remove boilerplate.
* meson-saradc
- style consistency fixes
* rockchip_saradc
- Allow compile testing with !ARM.
* st_lsm6dsx
- Changing scaling factor to use IIO_VAL_INT_PLUS_NANO to improve precision.
- Fix an issue with unchecked return value.
* stm32-adc
- Fix a missing return introduced in dev_err_probe() patch earlier in
cycle.

These seem to be up to date but never moved out of staging when the driver
did. Hence let us move them out now.

Since object temperature might be different than the sensor temperature
the infrared sensors should provide an interface to inject ambient
temperature. This was in past done via write to ambient temperature
interface (in_temp_ambient_raw), but I think most people did not know
about it. This solution introduces a new iio type of the CALIBAMBIENT
which is hopefully more descriptive and more explicit about the purpose
and capabilities of the sensors.
