1st set of IIO new device support, features and cleanup for 6.1
This includes Nuno Sa's work to move the IIO core over to generic firmware
properties rather than having DT specific code paths. Combined with Andy
Shevchenko's long term work on drivers, this leaves IIO in a good state for
handling other firmware types.
New device support
- liteon,ltrf216a
* New driver and dt bindings to support this Light sensor.
- maxim,max11205
* New driver for this 16bit single channel ADC.
- memsensing,msa311
* New driver for this accelerometer. Includes a string helper for read/write.
- richtek,rtq6056
* New driver and dt binding to support this current monitor used to measure
power usage.
- yamaha,yas530
* Support the YAS537 variant (series includes several fixes for other parts
and new driver features).
Staging graduation
- adi,ad7746 CDC. Cleanup conducted against set of roadtest tests using
the posted RFC of that framework.
Features
- core
* Large rework to make all the core IIO code use generic firmware properties.
Includes switching some drivers over as well using newly provided
generic interfaces and allowing removal of DT specific ones.
* Support for gesture event types for single and double tap. Used in
bosch,bma400.
- atmel,at91-sama5d2
* Add support for temperature sensor which uses two muxed inputs to estimate
the temperature.
* Handle trackx bits of EMR register to improve temp sampling accuracy.
* Runtime PM support.
- liteon,ltrf216a
* Add a _raw channel output to allow working around an issue with
differing conversions equations that breaks some user space controls.
- mexelis,mlx90632
* Support regulator control.
- ti,tsc2046
* External reference voltage support.
Clean up and minor fixes
- Tree-wide
* devm_clk_get_enabled() replacements of opencoded equivalent.
* Remaining IIO_DMA_MINALIGN conversions (the staging/iio drivers).
* Various minor warning and similar cleanup such as missing static
markings.
* strlcpy() to strscpy() for cases where return value not checked.
* provide units.h entries for more HZ units and use them in drivers.
- dt-bindings cleanup
* Drop maintainers listss where the email address is bouncing.
* Switch spi devices over to using spi-peripheral.yaml
* Add some missing unevaluatedProperties / additionalProperties: false
entries.
- ABI docs
* Add some missing channel type specific sampling frequency entries.
* Add parameter names for callback parameters.
- MAINTAINERS
* Fix wrong ADI forum links.
- core
* lockdep class per device, to avoid an issue with nest when one IIO
device is the consumer of another.
* White space tweaks.
- asc,dlhl60d
* Use get_unaligned_be24 to avoid some unusual data manipulation and masking.
- atmel,at91-sama5d2
* Fix wrong max value.
* Improve error handling when measuring pressure and touch.
* Add locks to remove races on updating oversampling / sampling freq.
* Add missing calls in suspend and resume path to ensure state is correctly
brought up if buffered capture was in use when suspend happened.
* Error out of write_raw() callback if buffered capture enabled to avoid
unpredictable behavior.
* Handle different versions having different oversampling ratio support and
drop excess error checking.
* Cleanup magic value defines where the name is just the value and hence
hurts readability.
* Use read_avail() callback to provide info on possible oversampling ratios.
* Correctly handle variable bit depth when doing oversampling on different
supported parts. Also handle higher oversampling ratios.
- fsl,imx8qxp
* Don't ignore errors from regulator_get_voltage() so as to avoid some
very surprising scaling.
- invensense,icp10100
* Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS. UNIVERSAL rarely made
sense and is now deprecated. In this driver we just avoid double disabling
in some paths.
- maxim,max1363
* Drop consumer channel map provision by platform data. There have been
better ways of doing this for years and there are no in tree users.
- microchip,mcp3911
* Update status to maintained.
- qcom,spmi-adc5
* Support measurement of LDO output voltage.
- qcom,spmi-adc

- ti,am335x
* Document ti,am654-adc compatible already in use in tree.
- ti,hmc5843

EMMC and NAND have the same clock control register named 'SD_EMMC_CLOCK'
which is defined in EMMC port internally. bit0~5 of 'SD_EMMC_CLOCK' is
the divider and bit6~7 is the mux for fix pll and xtal. At the beginning,
a common MMC and NAND sub-clock was discussed and planed to be implemented
as NFC clock provider, but now this series of patches of a common MMC and
NAND sub-clock are never being accepted and the current binding was never
valid. the reasons for giving up are:
1. EMMC and NAND, which are mutually exclusive anyway
2. coupling the EMMC and NAND.
3. it seems that a common MMC and NAND sub-clock is over engineered.
and let us see the link fot more information:
https://lore.kernel.org/all/20220121074508.42168-5-liang.yang@amlogic.com

The more sockets we have in the hash table, the longer we spend looking
up the socket. While running a number of small workloads on the same
host, they penalise each other and cause performance degradation.
The root cause might be a single workload that consumes much more
resources than the others. It often happens on a cloud service where
different workloads share the same computing resource.
On EC2 c5.24xlarge instance (196 GiB memory and 524288 (1Mi / 2) ehash
entries), after running iperf3 in different netns, creating 24Mi sockets
without data transfer in the root netns causes about 10% performance
regression for the iperf3's connection.
thash_entries sockets length Gbps
524288 1 1 50.7
24Mi 48 45.1
It is basically related to the length of the list of each hash bucket.
For testing purposes to see how performance drops along the length,
I set 131072 (1Mi / 8) to thash_entries, and here's the result.
thash_entries sockets length Gbps
131072 1 1 50.7
1Mi 8 49.9
2Mi 16 48.9
4Mi 32 47.3
8Mi 64 44.6
16Mi 128 40.6
24Mi 192 36.3
32Mi 256 32.5
40Mi 320 27.0
48Mi 384 25.0
To resolve the socket lookup degradation, we introduce an optional
per-netns hash table for TCP, but it's just ehash, and we still share
the global bhash, bhash2 and lhash2.
With a smaller ehash, we can look up non-listener sockets faster and
isolate such noisy neighbours. In addition, we can reduce lock contention.
We can control the ehash size by a new sysctl knob. However, depending
on workloads, it will require very sensitive tuning, so we disable the
feature by default (net.ipv4.tcp_child_ehash_entries == 0). Moreover,
we can fall back to using the global ehash in case we fail to allocate
enough memory for a new ehash. The maximum size is 16Mi, which is large
enough that even if we have 48Mi sockets, the average list length is 3,
and regression would be less than 1%.
We can check the current ehash size by another read-only sysctl knob,
net.ipv4.tcp_ehash_entries. A negative value means the netns shares
the global ehash (per-netns ehash is disabled or failed to allocate
memory).
# dmesg | cut -d ' ' -f 5- | grep "established hash"
TCP established hash table entries: 524288 (order: 10, 4194304 bytes, vmalloc hugepage)
# sysctl net.ipv4.tcp_ehash_entries
net.ipv4.tcp_ehash_entries = 524288 # can be changed by thash_entries
# sysctl net.ipv4.tcp_child_ehash_entries
net.ipv4.tcp_child_ehash_entries = 0 # disabled by default
# ip netns add test1
# ip netns exec test1 sysctl net.ipv4.tcp_ehash_entries
net.ipv4.tcp_ehash_entries = -524288 # share the global ehash
# sysctl -w net.ipv4.tcp_child_ehash_entries=100
net.ipv4.tcp_child_ehash_entries = 100
# ip netns add test2
# ip netns exec test2 sysctl net.ipv4.tcp_ehash_entries
net.ipv4.tcp_ehash_entries = 128 # own a per-netns ehash with 2^n buckets
When more than two processes in the same netns create per-netns ehash
concurrently with different sizes, we need to guarantee the size in
one of the following ways:
1) Share the global ehash and create per-netns ehash
First, unshare() with tcp_child_ehash_entries==0. It creates dedicated
netns sysctl knobs where we can safely change tcp_child_ehash_entries
and clone()/unshare() to create a per-netns ehash.
2) Control write on sysctl by BPF
We can use BPF_PROG_TYPE_CGROUP_SYSCTL to allow/deny read/write on
sysctl knobs.
Note that the global ehash allocated at the boot time is spread over
available NUMA nodes, but inet_pernet_hashinfo_alloc() will allocate
pages for each per-netns ehash depending on the current process's NUMA
policy. By default, the allocation is done in the local node only, so
the per-netns hash table could fully reside on a random node. Thus,
depending on the NUMA policy the netns is created with and the CPU the
current thread is running on, we could see some performance differences
for highly optimised networking applications.
Note also that the default values of two sysctl knobs depend on the ehash
size and should be tuned carefully:
tcp_max_tw_buckets : tcp_child_ehash_entries / 2
tcp_max_syn_backlog : max(128, tcp_child_ehash_entries / 128)
As a bonus, we can dismantle netns faster. Currently, while destroying
netns, we call inet_twsk_purge(), which walks through the global ehash.
It can be potentially big because it can have many sockets other than
TIME_WAIT in all netns. Splitting ehash changes that situation, where
it's only necessary for inet_twsk_purge() to clean up TIME_WAIT sockets
in each netns.
With regard to this, we do not free the per-netns ehash in inet_twsk_kill()
to avoid UAF while iterating the per-netns ehash in inet_twsk_purge().
Instead, we do it in tcp_sk_exit_batch() after calling tcp_twsk_purge() to
keep it protocol-family-independent.
In the future, we could optimise ehash lookup/iteration further by removing
netns comparison for the per-netns ehash.

Merge series from Martin Povišer <povik+lin@cutebit.org>:
there's a CS42L83 headphone jack codec found in Apple computers (in the
recent 'Apple Silicon' ones as well as in earlier models, one example
[1]). The part isn't publicly documented, but it appears almost
identical to CS42L42, for which we have a driver in kernel. This series
adapts the CS42L42 driver to the new part, and makes one change in
anticipation of a machine driver for the Apple computers.
Patch 1 adds new compatible to the cs42l42 schema.
Patches 2 to 7 are taken from Richard's recent series [2] adding
soundwire support to cs42l42. They are useful refactorings to build on
in the later patches, and also this way our work doesn't diverge.
(I fixed missing free_irq path in cs42l42_init, did
s/Soundwire/SoundWire/ in changelogs, rebased.)
Patch 8 exports some regmap-related symbols from cs42l42.c so they can
be used to create cs42l83 regmap in cs42l83-i2c.c later.
Patch 9 is the cs42l83 support proper.
Patch 10 implements 'set_bclk_ratio' on the cs42l42 core. This will be
called by the upcoming ASoC machine driver for 'Apple Silicon' Macs.
(We have touched on this change to be made in earlier discussion, see
[3] and replies.)
Patch 11 brings cs42l42-i2c.c in sync with cs42l83-i2c.c on
dev_err_probe() usage.

The ARTPEC-8 has an MCT with 4 global and 8 local timer interrupts.
The SoC has a quad-core Cortex-A53 and a single-core Cortex-A5 which
share one MCT with one global and eight local timers. The Cortex-A53
and Cortex-A5 do not have cache-coherency between them, and therefore
run two separate kernels.
The Cortex-A53 boots first and starts the global free-running counter
and also registers a clock events device using the global timer. (This
global timer clock events is usually replaced by arch timer clock events
for each of the cores.)
When the A5 boots (via the A53), it should not use the global timer
interrupts or write to the global timer registers. This is because even
if there are four global comparators, the control bits for all four are
in the same registers, and we would need to synchronize between the
cpus. Instead, the global timer FRC (already started by the A53) should
be used as the clock source, and one of the local timers which are not
used by the A53 can be used for clock events on the A5.
To support this hardware, add a compatible for the MCT as well as two
new properties to describe the hardware-mandated sharing of the FRC and
dedicating local timers to specific processors.

The fact that some DSA device trees use 'label = "cpu"' for the CPU port
is nothing but blind cargo cult copying. The 'label' property was never
part of the DSA DT bindings for anything except the user ports, where it
provided a hint as to what name the created netdevs should use.
DSA does use the "cpu" port label to identify a CPU port in dsa_port_parse(),
but this is only for non-OF code paths (platform data).
The proper way to identify a CPU port is to look at whether the
'ethernet' phandle is present.

If defined they shall be used instead of defaults.
The coefficients were added to device tree on top of the series property
(which can be used to select between series 5 and series 6), because
coefficients can vary between product and product, and code defaults might
