There's not much point in having unused labels in the binding example,
so drop them.
This patch was originally motivated by ea25d61b448a ("arm64: dts: qcom:
Use plural _gpios node label for PMIC gpios") updating all dts files to
use the plural _gpios label instead of the singular _gpio as label but
this example wasn't updated. But since we should just drop the label
alltogether, do that.

`strncpy` is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect project_name to be NUL-terminated based on its use with
pr_info:
| pr_info("PRCMU firmware: %s(%d), version %d.%d.%d\n",
| fw_info.version.project_name,
| fw_info.version.project,
| fw_info.version.api_version,
| fw_info.version.func_version,
| fw_info.version.errata);
Moreover, NUL-padding does not seem to be needed.
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Let's also change `PRCMU_FW_PROJECT_NAME_LEN` to just
sizeof(fw_info.version.project_name) as this is more idiomatic strscpy
usage.

The MT6366 PMIC is mostly, but not fully, compatible with MT6358. It has
a different set of regulators. Specifically, it lacks the camera related
VCAM* LDOs and VLDO28, but has additional VM18, VMDDR, and VSRAM_CORE LDOs.
The PMICs contain a chip ID register that can be used to detect which
exact model is preset, so it is possible to share a common base
compatible string.
Add a separate compatible for the MT6366 PMIC, with a fallback to the
MT6358 PMIC.

All X-Powers PMICs described by this binding have an IRQ pin, and so
far (almost) all boards connected this to some NMI pin or GPIO on the SoC
they are connected to.
However we start to see boards that omit this connection, and technically
the IRQ pin is not essential to the basic PMIC operation.
The existing Linux driver allows skipping the IRQ pin setup for two chips
already, so update the binding to also make the DT property optional for
the missing chip. And while we are at it, add the AXP313a to that list,
as they are actually boards out there not connecting the IRQ pin.
This allows to have DTs correctly describing those boards not wiring up
the interrupt.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct iqs62x_fw_blk.

than the rbtree cache and makes optimisation choices which are probably

v6.5 it has also acquired the ability to generate multi-register writes in

there.

At the moment we allow the AXP15060 and the AXP806 PMICs to omit the
interrupt line to the SoC, and we skip registering the PEK (power key)
driver in this case, since that crashes when no IRQ is described in the
DT node.
The IRQ pin potentially not being connected to anything does affect more
PMICs, though, and the PEK driver is not the only one requiring an
interrupt: at least the AC power supply driver crashes in a similar
fashion.
Generalise the handling of AXP MFD devices when the platform tables
describe no interrupt, by allowing each device to specify an alternative
MFD list for this case. If no specific alternative is specified, we go
with the safe default of "just the regulators", which matches the current
situation.
This enables new devices using the AXP313a PMIC, but not connecting the
IRQ pin.
