Set version to 2.6.0-rc2

Signed-off-by: Kumar Gala <kumar.gala@linaro.org>

Microchip HAL 1.2.0 fixed a bug in the define of GPIO
control register MUX field. The incorrect MUX defined
cleared by GPIO input pad disable field by accident.
After the MUX definition was corrected the pinmux driver
must be modified to mask off the input pad disable for
the pin to be operational.

Minor documentation fixes for the DT overlay files for

Update overlay file for nucleo_l552ze_q_ns board,
since now the sample does not enable REGRESSION,
and thus regular TF-M flash layout for the board
is used.

The flash layout definition has changed in upstream TF-M for the

Removes the dependency on the external test service from the

The TF-M update brings in the latest PSA crypto headers,

platforms.

After the ARM/ARM64 split the SDK 0.12.4 is needed to be able to compile
the ARM64 arch code. Bail out if an old SDK is detected at compile time.

Also change the minimal supported Zephyr SDK to v0.12, as agreed in
Toolchain WG.  Main reason is added compiler architectures and important
inclusion of fixes, for example qemu and arm fixes for veneers (TFM)

Due to the fact that we use -mcpu=hs as a default for ARCv2 HS
the compiler doesn't generate multiply/divide/mac/64bit memory
operations instructions.

Fix that by using -mcpu=archs as a default for ARCv2 HS which is
fits for all existing boards with ARCv2 HS CPU.

People seem to miss the troubleshooting page a lot, since nobody ever
mentions that they tried its steps and they didn't work. Promote it to
a top level page to make it easier to see. Add cross-references
between the two to keep them well linked together.

here, now that the bindings docs are a bit better off than they were

Fixes: #32237

When building for native_posix, then host tools are used.
This means that gcc will link using `/usr/bin/ld` per default.

If ld points to lld, then linking will fail.

This commit will first look for ld.bfd, and if found then use
-fuse-ld=bfd for linking. If ld.bfd is not found, then ld is used as
fallback as that will be assumed to be the best working candidate.

Assuming that pm_device_state_set is synchronous it is possible to
simplify the mutex usage. Now there are two places where the lock is
held, one in the worqueue handler and other in pm_device_request to
cover the synchronous path. It is no longer needed held the lock in the
pm_device_state_set callback and not needed to wait on the conditional
variable after set the state in the synchronous path.

Most APIs have the default synchronous and an asynchronous version
with the sufix _async because that is the most common use.

All devices in tree right now are using the synchronous version, so
