hwicap_drv_remove() is only called for a device after hwicap_drv_probe()
returned 0. In that case dev_set_drvdata() was called (by hwicap_setup())
with a non-NULL value and so dev_get_drvdata() won't return NULL.

A process can spawn a PD on DSP with some attributes that can be
associated with the PD during spawn and run. The invocation
corresponding to the create request with attributes has total
4 buffers at the DSP side implementation. If this number is not
correct, the invocation is expected to fail on DSP. Added change
to use correct number of buffer count for creating fastrpc scalar.

In a couple of situations like

the error is not actually "No space left on device", but "Out of memory".
It is semantically correct to return -ENOMEM in all failed kstrndup()
and kzalloc() cases in this driver, as it is not a problem with disk
space, but with kernel memory allocator failing allocation.
The semantically correct should be:
name = kstrndup(buf, count, GFP_KERNEL);

This adds support for the "fixed-layout" NVMEM layout binding. It allows
defining NVMEM cells in a layout DT node named "nvmem-layout".
While NVMEM subsystem supports layout drivers it has been discussed that
"fixed-layout" may actually be supperted internally. It's because:
1. It's a very basic layout
2. It allows sharing code with legacy syntax parsing
3. It's safer for soc_device_match() due to -EPROBE_DEFER
4. This will make the syntax transition easier

With the introduction of NVMEM layouts, new NVMEM content structures
should be defined as such. We should also try to convert / migrate
existing NVMEM content bindings to layouts.
This commit handles fixed NVMEM cells. So far they had to be defined
directly - as device subnodes. With this change it's allowed to put them
in the DT node named "nvmem-layout".
Having NVMEM cells in separated node is preferred as it draws a nice
line between NVMEM device and its content. It results in cleaner
bindings.
FWIW a very similar situation has happened to MTD devices and their
partitions: see commit 5d96ea42eb ("dt-bindings: mtd: Clarify all

Broadcom's NVRAM contains MACs for Ethernet interfaces. Those MACs are
usually base addresses that are also used for calculating other MACs.
For example if a router vendor decided to use gmac0 it most likely
programmed NVRAM of each unit with a proper "et0macaddr" value. That is
a base.
Ethernet interface is usually connected to switch port. Switch usually
includes few LAN ports and a WAN port. MAC of WAN port gets calculated
as relative address to the interface one. Offset varies depending on
device model.
Wireless MACs may also need to be calculated using relevant offsets.
To support all those scenarios let MAC NVMEM cells be referenced with an
index specifying MAC offset. Disallow additionalProperties while at it.

New device support
- honeywell,mprls0025pa
* New driver and dt-bindings for this series of pressure sensors.
- invensense,mpu6050
* Add support for ICM 20600 IMU (ID, bindings and device data).
- melexis,mlx90614
* Add support for mlx90615 Infra Red Thermometer after driver cleanup
and refactoring to support the differences in this device.
- renesas,x9250
* New driver and bindings for this quad potentiometer.
- rockchip,saradc
* Add support for RK3588. Also included is a bunch of refactoring and
cleanup for that driver.
- rohm,bu27008
* New driver bindings etc for this 5 photodiode color sensor.
- st,lsm9ds0/st,st-sensors
* ID added for LSM303D accelerometer and magnetometer including ACPI binding.
- ti,opt4001
* New driver and bindings for this ambient light sensor.
Features
- core
* Introduce iio_validate_own_trigger() for cases where a driver can only
consumer a trigger it registered (detected via same parent device).
Use it in the kionix,kx022a driver and new rohm,by27008 driver.
- dynaimage,al3320a
* ACPI binding CALS0001 seen on Lenovo Yoga Table 2 devices.
- kionix,kx002a
* Enable asynchronous probe.
- rohm,bu27034
* Enable asynchronous probe.
- ti,tmp006
* Explicit support for DT including binding documentation.
Cleanups, minor fixes and misc improvements.
- treewide
* Switch I2C drivers from probe_new() back to probe() - part of the
long process of getting rid of a parameter from probe()
* Various whitespace and typo fixes not otherwise called out.
- core
* industrialio-buffer,Style cleanup.
* Add documentation to extend_name field of struct iio_chan_spec to
direct people using it towards the label infrastructure instead.
extend_name was a design mistake a long time back so directly people
away from it may be useful.
- adi,ad7606
* Add HAS_IOPORT dependency to prepare for some Kconfig changes.
- bosch,bma400
* Drop pointless print of ret in a dev_err_probe() message.
- invensense,icm42600
* Rework timestamp handling to reduce jitter.
- mediatek,mt7986-auxdac
* Add DT binding for this part.
- qcom,spmi-vadc
* Allow for 1/16th prescaling used on a few devices.
* Various changes to channel labeling and naming, including dropping
use of fwnode_name which generates odd channel names. Small ABI
change as a result, but not thought to be a problem for users of this
platform.
- st,lsm6dsx
* dt-binding: Use common schema for mount-matrix via a reference.
- st,stm32
* Add a debug print for when legacy channel config is used.
- ti,palmas-adc
* Drop unused i2c.h include.

According to the datasheets of supported meson SoCs length of ADC_CLK_DIV
field is 6-bit. Although all supported SoCs have the register
with that field documented later SoCs use external clock rather than
ADC internal clock so this patch affects only meson8 family (S8* SoCs).

Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8254 Programmable Interval Timer
(PIT).
The Intel 8254 PIT first appeared in the early 1980s and was used
initially in IBM PC compatibles. The popularity of the original Intel
825x family of chips led to many subsequent variants and clones of the
interface in various chips and integrated circuits. Although still
popular, interfaces compatible with the Intel 8254 PIT are nowdays
typically found embedded in larger VLSI processing chips and FPGA
components rather than as discrete ICs.
A CONFIG_I8254 Kconfig option is introduced by this patch. Modules
wanting access to these i8254 library functions should select this
Kconfig option, and import the I8254 symbol namespace.
