Some RTCs can be equipped with a chargeable battery or supercap.
Every RTC allowing this whose driver's implement it are charged by
default. To disable this the trickle-diode-disable flag exists.
If a driver did not support charging and some time later one wants to
add that feature, there is currently no way to do it without breaking
dt backwards compatibility. RTCs on boards without the
trickle-diode-disable flag in their device tree would suddenly charge
their battery/supercap which is a change in behavior.
Change that by introducing aux-voltage-chargeable, not as a flag but as
a uint32 enum allowing to set "do not charge" (0) or "charge" (1). This
dt property is optional, so we can now distinguish these cases.
Care must be taken to support the old behavior for device trees without
aux-voltage-chargeable nonetheless to stay compatible.

Pull device mapper fixes from Mike Snitzer:
- DM core fix for incorrect double bio splitting. Keep "fixing" this
because past attempts didn't fully appreciate the liability relative
to recursive bio splitting. This fix limits DM's bio splitting to a
single method and does _not_ use blk_queue_split() for normal IO.
- DM crypt Documentation updates for features added during 5.9 merge.

pmbus_do_probe doesn't use the id information provided in its second
argument, so this can be removed, which then allows using the
single-parameter i2c probe function ("probe_new") for probes.
This avoids scanning the identifier tables during probes.
Drivers which didn't use the id are converted as-is; drivers which did
are modified as follows:
* if the information in i2c_client is sufficient, that's used instead
(client->name);
* configured v. probed comparisons are performed by comparing the
configured name to the detected name, instead of the ids; this
involves strcmp but is still cheaper than comparing all the device
names when scanning the tables;
* anything else is handled by calling i2c_match_id() with the same
level of error-handling (if any) as before.
Additionally, the mismatch message in the ltc2978 driver is adjusted
so that it no longer assumes that the driver_data is an index into
ltc2978_id.

The J7200 SoC is a part of the K3 Multicore SoC architecture platform.
It is targeted for automotive gateway, vehicle compute systems,
Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) applications.
The SoC aims to meet the complex processing needs of modern embedded
products.
Some highlights of this SoC are:
* Dual Cortex-A72s in a single cluster, two clusters of lockstep
capable dual Cortex-R5F MCUs and a Centralized Device Management and
Security Controller (DMSC).
* Configurable L3 Cache and IO-coherent architecture with high data
throughput capable distributed DMA architecture under NAVSS.
* Integrated Ethernet switch supporting up to a total of 4 external ports
in addition to legacy Ethernet switch of up to 2 ports.
* Upto 1 PCIe-GEN3 controller, 1 USB3.0 Dual-role device subsystems,
20 MCANs, 3 McASP, eMMC and SD, OSPI/HyperBus memory controller, I3C and
I2C, eCAP/eQEP, eHRPWM among other peripherals.
* One hardware accelerator block containing AES/DES/SHA/MD5 called SA2UL
management.

When WIZ wraps a Cadence Torrent PHY (instead of Cadence Sierra PHY)
there is a difference in the refclk-dig node: Torrent only has two
clocks instead of Sierra's four clocks. Add minItems: 2 to solve this.
Additionally, in our use case we only need to use assigned-clock for a
single clock, but the current binding requires either no assigned-clocks
or two. Fix this by adding minItems: 1 to all the assigned-clock
properties.
There was also an extra trailing whitespace, which this patch removes.

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

The Nitro Enclaves driver handles the enclave lifetime management. This
includes enclave creation, termination and setting up its resources such
as memory and CPU.
An enclave runs alongside the VM that spawned it. It is abstracted as a
process running in the VM that launched it. The process interacts with
the NE driver, that exposes an ioctl interface for creating an enclave
and setting up its resources.
Changelog
v9 -> v10
* Update commit message to include the changelog before the SoB tag(s).
v8 -> v9
* No changes.
v7 -> v8
* Add NE custom error codes for user space memory regions not backed by
pages multiple of 2 MiB, invalid flags and enclave CID.
* Add max flag value for enclave image load info.
v6 -> v7
* Clarify in the ioctls documentation that the return value is -1 and
errno is set on failure.
* Update the error code value for NE_ERR_INVALID_MEM_REGION_SIZE as it
gets in user space as value 25 (ENOTTY) instead of 515. Update the
NE custom error codes values range to not be the same as the ones
defined in include/linux/errno.h, although these are not propagated
to user space.
v5 -> v6

* Update documentation to kernel-doc format.
* Remove the ioctl to query API version.
v4 -> v5
* Add more details about the ioctl calls usage e.g. error codes, file
descriptors used.
* Update the ioctl to set an enclave vCPU to not return a file
descriptor.
* Add specific NE error codes.
v3 -> v4
* Decouple NE ioctl interface from KVM API.
* Add NE API version and the corresponding ioctl call.
* Add enclave / image load flags options.
v2 -> v3
* Remove the GPL additional wording as SPDX-License-Identifier is
already in place.
v1 -> v2
* Add ioctl for getting enclave image load metadata.
* Update NE_ENCLAVE_START ioctl name to NE_START_ENCLAVE.
* Add entry in Documentation/userspace-api/ioctl/ioctl-number.rst for NE

The DT example erronously uses the "renesas,r8a7795-dw-hdmi", when the
correct value is "renesas,r8a7795-hdmi". It is furthermore missing the
generic "renesas,rcar-gen3-hdmi" compatible string. Fix it.

Dictionaries are only used for SUBSYSTEM and DEVICE properties. The
current implementation stores the property names each time they are
used. This requires more space than otherwise necessary. Also,
because the dictionary entries are currently considered optional,
it cannot be relied upon that they are always available, even if the
writer wanted to store them. These issues will increase should new
dictionary properties be introduced.
Rather than storing the subsystem and device properties in the
dict ring, introduce a struct dev_printk_info with separate fields
to store only the property values. Embed this struct within the
struct printk_info to provide guaranteed availability.
