Add support for the OrangePi NEO-01. It uses different registers for PWM
manual mode, set PWM, and read fan speed than previous devices. Valid PWM
input and duty cycle is 1-244, we scale this from 1-255 to maintain
compatibility with the existing interface.
Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use
new registers for turbo button takeover and read fan speed. X1 has an Intel
variant so change the CPU detection at init to only check for the affected
devices. While at it, adjust formatting of some constants and reorder all
cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI
for disambiguation. Update code comments for clarity.
Add support for AYANEO models 2S, AIR 1S, Flip series, GEEK 1S, and KUN.

The SC27XX fuel gauge supports a low voltage alarm IRQ, which is used
for more accurate battery capacity measurements with lower voltages.
This was unfortunately never documented in bindings, do so now.
The only in-tree user (sc2731.dtsi) has had interrupts specified
since its initial fuel-gauge submission and the current kernel
driver returns an error when no interrupt is specified, so also
add it to the required list.

The existing docs here are a bit vague. This reformats and rewords it,
and is based upon the wording originally used by the dell-laptop driver
battery documentation and also sysfs-class-power-wilco.
The wording for "Long Life" and "Bypass" remain the same, because I'm
unfamiliar with hardware that use them.

Rewrite the short document on bisecting kernel bugs. The new text
improves .config handling, brings a mention of 'git bisect skip', and
explains what to do after the bisection finished -- including trying a
revert to verify the result. The rewrite at the same time removes the
unrelated and outdated section on 'Devices not appearing' and replaces
some sentences about bug reporting with a pointer to the document
covering that topic in detail.
This overall brings the approach close to the one in the recently added
text Documentation/admin-guide/verify-bugs-and-bisect-regressions.rst.
As those two texts serve a similar purpose for different audiences,
mention that document in the head of this one and outline when the
other might be the better one to follow.

Add a option "trace_printk_dest" that will make the tracing instance the
location that trace_printk() will go to. This is useful if the
trace_printk or one of the top level tracers is too noisy and there's a
need to separate the two. Then an instance can be created, the
trace_printk can be set to go there instead, where it will not be lost in
the noise of the top level tracer.
Note, only one instance can be the destination of trace_printk at a time.
If an instance sets this flag, the instance that had it set will have it
cleared. There is always one instance that has this set. By default, that
is the top instance. This flag cannot be cleared from the top instance.
Doing so will result in an -EINVAL. The only way this flag can be cleared
from the top instance is by another instance setting it.

If the persistent boot mapped ring buffer is used for trace_printk(),
force it to not use the binary versions. trace_printk() by default uses
bin_printf() that only saves the pointer to the format and not the format
itself inside the ring buffer. But for a persistent buffer that is read
after reboot, the pointers to the format strings may not be the same, or
worse, not even exist! Instead, just force the more robust, but slower,
version that does the formatting before saving into the ring buffer.
The boot mapped buffer can now be used for trace_printk and friends!
Using the trace_printk() and the persistent buffer was used to debug the
issue with the osnoise tracer:

Currently, trace_printk() just goes to the top level ring buffer. But
there may be times that it should go to one of the instances created by
the kernel command line.
Add a new trace_instance flag: traceprintk (also can use "printk" or
"trace_printk" as people tend to forget the actual flag name).
trace_instance=foo^traceprintk
Will assign the trace_printk to this buffer at boot up.

Add a "flags" delimiter (^) to the "trace_instance" kernel command line
parameter, and add the "traceoff" flag. The format is:
trace_instance=<name>[^<flag1>[^<flag2>]][@<memory>][,<events>]
The code allows for more than one flag to be added, but currently only
"traceoff" is done so.
The motivation for this change came from debugging with the persistent
ring buffer and having trace_printk() writing to it. The trace_printk
calls are always enabled, and the boot after the crash was having the
unwanted trace_printks from the current boot inject into the ring buffer
with the trace_printks of the crash kernel, making the output very
confusing.

diagnostics: Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD). By introducing `ETHTOOL_A_CABLE_RESULT_SRC` and
`ETHTOOL_A_CABLE_FAULT_LENGTH_SRC` attributes, this update enables
drivers to indicate whether the result was derived from TDR or ALCD,
improving the clarity and utility of diagnostic information.

Adds support in the OP-TEE drivers (both SMC and FF-A ABIs) to probe and
use an RPMB device via the RPMB subsystem instead of passing the RPMB
frames via tee-supplicant in user space. A fallback mechanism is kept to
route RPMB frames via tee-supplicant if the RPMB subsystem isn't
available.
The OP-TEE RPC ABI is extended to support iterating over all RPMB
devices until one is found with the expected RPMB key already
programmed.

SG2042 use Synopsys dwcnshc IP for SD/eMMC controllers.
SG2042 defines 3 clocks for SD/eMMC controllers.
- EMMC_100M/SD_100M for cclk(Card clocks in DWC_mshc), so reuse
existing "core".
- AXI_EMMC/AXI_SD for aclk/hclk(Bus interface clocks in DWC_mshc)
and blck(Core Base Clock in DWC_mshc), these 3 clocks share one
source, so reuse existing "bus".
- 100K_EMMC/100K_SD for cqetmclk(Timer clocks in DWC_mshc), so reuse
existing "timer" which was added for rockchip specified.

The SD/MMC block on the RZ/V2H(P) ("R9A09G057") SoC is similar to that
of the R-Car Gen3, but it has some differences:
- HS400 is not supported.
- It has additional SD_STATUS register to control voltage,
power enable and reset.
- It supports fixed address mode.
To accommodate these differences, a SoC-specific 'renesas,sdhi-r9a09g057'
compatible string is added.

Document DU found in RZ/G2UL SoC. The DU block is identical to RZ/G2L
SoC, but has only DPI interface.
While at it, add missing required property port@1 for RZ/G2L and RZ/V2L
SoCs. Currently there is no user for the DPI interface and hence there
won't be any ABI breakage for adding port@1 as required property for
RZ/G2L and RZ/V2L SoCs.
