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
* Add missing channel available on SM6125 SoC.
- st,stmpe
* Drop requirement on node name in binding now that driver correctly
doesn't enforce it.
- stx104
* Move to more appropriate addac directory
- ti,am335x
* Document ti,am654-adc compatible already in use in tree.
- ti,hmc5843
* Move dev_pm_ops out of header and use new pm macros to handle export.
- yamaha,yas530

The next 2 patches are also by me and target the gs_usb driver. A
potential race condition during the ndo_open callback as well as the
return value if the ethtool identify feature is not supported are
fixed.

If it mixes core and uncore events, each evsel would have different cpu map.
But it assumed they are same with evlist's all_cpus and accessed by the same
index. This resulted in a crash like below.
$ perf stat -a --bpf-counters --for-each_cgroup ^. -e cycles,imc/cas_count_read/ sleep 1
Segmentation fault
While it's not recommended to use uncore events for cgroup aggregation, it
should not crash.

It seems the recent libbpf got more strict about the section name.
I'm seeing a failure like this:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup ^. sleep 1
libbpf: prog 'on_cgrp_switch': missing BPF prog type, check ELF section name 'perf_events'
libbpf: prog 'on_cgrp_switch': failed to load: -22
libbpf: failed to load object 'bperf_cgroup_bpf'
libbpf: failed to load BPF skeleton 'bperf_cgroup_bpf': -22
Failed to load cgroup skeleton
The section name should be 'perf_event' (without the trailing 's').
Although it's related to the libbpf change, it'd be better fix the
section name in the first place.

This loop intends to retry a max of 10 times, with some implicit
termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the
termination condition depends on the value reported by the SD card
(*rocr), which may or may not correctly reflect what we asked it to do.
Needless to say, it's not wise to rely on the card doing what we expect;
we should at least terminate the loop regardless. So, check both the
input and output values, so we ensure we will terminate regardless of
the SD card behavior.
Note that SDIO learned a similar retry loop in commit 0797e5f1453b
("mmc: core: Fixup signal voltage switch"), but that used the 'ocr'
result, and so the current pre-terminating condition looks like:
rocr & ocr & R4_18V_PRESENT
(i.e., it doesn't have the same bug.)
This addresses a number of crash reports seen on ChromeOS that look
like the following:
... // lots of repeated: ...

Cheap clone controllers may (falsely) report as having a user

wrong/impossible values for the actual calibration data.
In the present case at mine, the controller reports having a
user calibration in place and successfully executes the read
commands. The reported user calibration however is
min = center = max = 0.
This pull request addresses problems of this kind by checking the
provided user calibration-data for plausibility (min < center < max)
and falling back to the default values if implausible.
I'll note that I was experiencing a crash because of this bug when using
the GuliKit KingKong 2 controller. The crash manifests as a divide by

Now, register_pernet_subsys() and register_netdevice_notifier() are both
after sock_register(). It can create PF_PACKET socket and process socket
once sock_register() successfully. It is possible PF_PACKET socket is
creating but register_pernet_subsys() and register_netdevice_notifier()
are not registered yet. Thus net->packet.sklist_lock and net->packet.sklist
will be accessed without initialization that is done in packet_net_init().
Although this is a low probability scenario.
Move register_pernet_subsys() and register_netdevice_notifier() to the
front in packet_init(). Correspondingly, adjust the unregister process
in packet_exit().

If aq_nic_stop() fails, aq_ndev_close() returns err without calling
aq_nic_deinit() to release the relevant memory and resource, which
will lead to a memory leak.
We can fix it by deleting the if condition judgment and goto statement to

... the problem being that when LTO is enabled, <asm/rwonce.h> includes
<asm/alternative-macros.h>, and causes a circular include dependency
through <linux/bug.h>. This manifests as BUILD_BUG_ON() not being
defined when used within <asm/alternative-macros.h>.
This patch avoids the problem and simplifies the include dependencies by
using compiletime_assert() instead of BUILD_BUG_ON().

LEDs would behave differently depending on the blink hardware
acceleration configuration. This commit will make LEDs respond exactly
the same independently of the hardware acceleration status.
In other words, if you had two pca963x, side by side, one with blink
hardware acceleration "ON" and the other "OFF; and performed some
arbitrary sequence of API calls (e.g. turn on/off, change brightness,
change blink mode, etc.) you probably would end with not matching LED
states.
'pca963x software blink' and 'leds-gpio' behavior were used as
reference.
Actual chip used to validate this change: pca9634
Some of the unmatched behaviors being fixed are (when hw blink was "ON")
- Leds would stop blinking when the brightness was changed.
- Leds would persist their blinking mode even after being
turned off (brightness = 0).
- Leds would only blink if another led was solid (pca963x will be
forced out of low power)

Coccinelle reports a warning:
WARNING: use scnprintf or sprintf
This LWN article explains the rationale for this change:
https: //lwn.net/Articles/69419/
Ie. snprintf() returns what *would* be the resulting length,
while scnprintf() returns the actual length.
Adding to that, there has also been some slow migration from snprintf to scnprintf,
here's the shift in usage in the past 3.5 years, in all fs/ files:
v5.0 v6.0-rc6
--------------------------------------
snprintf() uses: 63 213
scnprintf() uses: 374 186
No intended change in behavior.

The entries in the .parainstructions sections are 8 byte aligned and the
corresponding C struct paravirt_patch_site makes the array offset 16
bytes.
Though the pushed entries are only using 12 bytes, __parainstructions_end
is therefore 4 bytes short.
That works by chance because it's only used in a loop:
for (p = start; p < end; p++)
But this falls flat when calculating the number of elements:
n = end - start
That's obviously off by one.
Ensure that the gap is filled and the last entry is occupying 16 bytes.

The ubifs_compress() function does not compress the data When the
data length is short than 128 bytes or the compressed data length
is not ideal.It cause that the compressed length of the truncated
data in the truncate_data_node() function may be greater than the
length of the raw data read from the flash.
The above two lengths are transferred to the ubifs_encrypt()
function as parameters. This may lead to assertion fails and then
the file system becomes read-only.
This patch use the actual length of the data in the memory as the
input parameter for assert comparison, which avoids the problem.
