Add a new compatible string "qcom,pmk8350-pon" for GEN3 PMIC PON
peripherals and update "reg" property.
Also, Add an optional "reg-names" property to differentiate between
GEN1/GEN2 and GEN3 peripherals. GEN1/GEN2 peripherals only need one
register address to be specified (e.g. "pon") whereas GEN3 peripherals
can have two register addresses specified ("hlos", "pbs").

In our environment, it was found that the mitigation BHB has a great
impact on the benchmark performance. For example, in the lmbench test,
the "process fork && exit" test performance drops by 20%.
So it is necessary to have the ability to turn off the mitigation
individually through cmdline, thus avoiding having to compile the
kernel by adjusting the config.

SMD edge contains subnodes representing devices related to the remote
processor. With limietd number of remote processors, there is a limited
set of such devices.
List all of them in smd-edge bindings so schema can strictly check for
subnodes.
Additional benefit is requirement of "qcom,smd-channels" for such
subnodes, because their schema cannot enforce it (few devices like APR
or FastRPC can be part of either SMD or GLINK edge).

GLINK edge contains subnodes representing devices related to the remote
processor. Each of such device (e.g. APR or FastRPC) must have
a "qcom,glink-channels" property. However the APR or FastRPC device can
be also part of other communication - SMD - thus their schema does not
require "qcom,glink-channels".
To make the GLINK edge bindings strict, require "qcom,glink-channels"
for its children.

PSI accounts stalls for each cgroup separately and aggregates it
at each level of the hierarchy. This may cause non-negligible overhead
for some workloads when under deep level of the hierarchy.
commit 3958e2d0c34e ("cgroup: make per-cgroup pressure stall tracking configurable")
make PSI to skip per-cgroup stall accounting, only account system-wide
to avoid this each level overhead.
But for our use case, we also want leaf cgroup PSI stats accounted for
userspace adjustment on that cgroup, apart from only system-wide adjustment.
So this patch introduce a per-cgroup PSI accounting disable/re-enable
interface "cgroup.pressure", which is a read-write single value file that
allowed values are "0" and "1", the defaults is "1" so per-cgroup
PSI stats is enabled by default.
Implementation details:
It should be relatively straight-forward to disable and re-enable
state aggregation, time tracking, averaging on a per-cgroup level,
if we can live with losing history from while it was disabled.
I.e. the avgs will restart from 0, total= will have gaps.
But it's hard or complex to stop/restart groupc->tasks[] updates,
which is not implemented in this patch. So we always update
groupc->tasks[] and PSI_ONCPU bit in psi_group_change() even when
the cgroup PSI stats is disabled.

Now PSI already tracked workload pressure stall information for
CPU, memory and IO. Apart from these, IRQ/SOFTIRQ could have
obvious impact on some workload productivity, such as web service
workload.
When CONFIG_IRQ_TIME_ACCOUNTING, we can get IRQ/SOFTIRQ delta time
from update_rq_clock_task(), in which we can record that delta
to CPU curr task's cgroups as PSI_IRQ_FULL status.
Note we don't use PSI_IRQ_SOME since IRQ/SOFTIRQ always happen in
the current task on the CPU, make nothing productive could run
even if it were runnable, so we only use PSI_IRQ_FULL.

For RPMH regulators it doesn't make sense to indicate
regulator-allow-set-load without saying what modes you can switch to,
so be sure to indicate a dependency on regulator-allowed-modes.
In general this is true for any regulators that are setting modes
instead of setting a load directly, for example RPMH regulators. A
counter example would be RPM based regulators, which set a load
change directly instead of a mode change. In the RPM case
regulator-allow-set-load alone is sufficient to describe the regulator
(the regulator can change its output current, here's the new load),
but in the RPMH case what valid operating modes exist must also be
stated to properly describe the regulator (the new load is this, what
is the optimum mode for this regulator with that load, let's change to
that mode now).
With this in place devicetree validation can catch issues like this:
/mnt/extrassd/git/linux-next/arch/arm64/boot/dts/qcom/sm8350-hdk.dtb: pm8350-rpmh-regulators: ldo5: 'regulator-allowed-modes' is a dependency of 'regulator-allow-set-load'
From schema: /mnt/extrassd/git/linux-next/Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.yaml
Where the RPMH regulator hardware is described as being settable, but
there are no modes described to set it to!

One of the "legitimate" uses of strncpy() is copying a NUL-terminated
string into a fixed-size non-NUL-terminated character array. To avoid
the weaknesses and ambiguity of intent when using strncpy(), provide
replacement functions that explicitly distinguish between trailing
padding and not, and require the destination buffer size be discoverable
by the compiler.
For example:
struct obj {
int foo;
char small[4] __nonstring;
char big[8] __nonstring;
int bar;
};
struct obj p;
/* This will truncate to 4 chars with no trailing NUL */
strncpy(p.small, "hello", sizeof(p.small));
/* p.small contains 'h', 'e', 'l', 'l' */
/* This will NUL pad to 8 chars. */
strncpy(p.big, "hello", sizeof(p.big));
/* p.big contains 'h', 'e', 'l', 'l', 'o', '\0', '\0', '\0' */
When the "__nonstring" attributes are missing, the intent of the
programmer becomes ambiguous for whether the lack of a trailing NUL
in the p.small copy is a bug. Additionally, it's not clear whether
the trailing padding in the p.big copy is _needed_. Both cases
become unambiguous with:
strtomem(p.small, "hello");
strtomem_pad(p.big, "hello", 0);
See also https://github.com/KSPP/linux/issues/90
Expand the memcpy KUnit tests to include these functions.

of the Crypto module, it is not dedicated to the RNG module and cannot be
controlled by the RNG driver. The driver does not require this clock to
always be defined and the DT binding should not force it either.
Remove this so we can start dropping out the clock properties as needed.

Allwinner's I2C offload engine includes bidirectional DMA support. Add
the properties for describing this in the devicetree. "dmas" is optional
because not all instances of the controller have their DRQs hooked up.
For example, R_I2C0 and R_I2C1 on V536 have no DRQ number assigned.

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate
dt-entries correctly and any future additions can go into yaml format.
Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and
qcom,smd-channels missing properties to make sure dtbs_check doesn't fail
right off the bat. Correct the name of the parent node in the example from
smd-edge to glink-edge.
Since now the qcom,fastrpc bindings document is yaml, update the
reference to it in qcom,glink-edge and also use $ref.
Also update the MAINTAINERS file to point to the yaml version.

Rework/modernize docs:
- use /proc/dynamic_debug/control in examples
its *always* there (when dyndbg is config'd), even when <debugfs> is not.
drop <debugfs> talk, its a distraction here.
- alias ddcmd='echo $* > /proc/dynamic_debug/control
focus on args: declutter, hide boilerplate, make pwd independent.
- swap sections: Viewing before Controlling. control file as Catalog.
- focus on use by a system administrator
add an alias to make examples more readable
drop grep-101 lessons, admins know this.
- use init/main.c as 1st example, thread it thru doc where useful.
everybodys kernel boots, runs these.
- add *prdbg* api section
to the bottom of the file, its for developers more than admins.
move list of api functions there.
- simplify - drop extra words, phrases, sentences.
- add "decorator" flags line to unify "prefix", trim fmlt descriptions

Convert the Samsung Exynos SoC G-Scaler bindings to DT schema.
Changes done during conversion:
1. A typical (already used) properties like clocks, iommus and
power-domains.
2. Require clocks, because they are essential for the block to operate.
3. Describe the differences in clocks between the Exynos5250/5420 and
the Exynos5433 G-Scalers. This includes the fifth Exynos5433 clock
"gsd" (GSCL Smart Deck) which was added to the DTS, but not to the
bindings and Linux driver. Similarly to Exynos5433 DECON change [1],
the clock should be used.
