If next_timeout() returns INT_MAX and pass it to
z_clock_set_timeout(), and machine goes to freeze or slow down.
Bad scenario as follows:
- If an argument int32_t ticks is set large value 0xffffffff,
ticks = MAX(MIN(ticks - 1, (int32_t)MAX_TICKS), 0);
replaces it into MAX_TICKS.
- uint32_t cyc will be set near by 0xffffffff
(this is 0xfffd7280 in 100 ticks per second).
- Add adjustment to cyc, adjustment max value is MAX_CYC.
(cyc = 0xffff14fd)
- Over 0x80000000 value of uint32_t is considered as negative
value of int32_t.
if ((int32_t)(cyc + last_count - now) < MIN_DELAY)
This condition is always true.
- Because cyc += CYC_PER_TICK will get overflow, driver sets mtimecmp
near value of current mtime.
(cyc = 0x00007fc0)
- Next timer interrupt will happen soon after return from interrupt
handler.
- By repeating these events, machine cannot go to next instruction,
and it's going to freeze or slow down.

Move the ticker job_guard reset to after
ticker_job_compare_update, so that the ticks_current and
ticks_slot_previous are updated before ticker_worker gets

ticker_worker will use incorrect ticks_slot_previous and
ticks_current value under race conditions.

Fix ticker job to defer itself to avoid recursive

In case the endpoint string provided by the application is longer or
equal to CLIENT_EP_LEN - 1, the strncpy() function will not add the NULL
terminator. As the endpoint buffer is treated as a C-string in other

explicitly at the end of the buffer.

This commit is a followup to #31877 where the `${shield_dir}/${s_dir}`
was adjusted to `${SHIELD_DIR_${s}}` to ensure only including shields

An `if(EXISTS ${shield_dir}/${s_dir}...)` was missed in this process
which causes #32269. This is corrected in this commit.

When running the tests of the async api of uart
on nucleo-l4r5zi we get MPU fault.
The reason is ordering initialization. The uart and dma
drivers are initialized PRE_KERNEL_1 while dmamux is
initialized POST_KERNEL.
Thus, the function device_get_binding fails since the
dmamux device is not ready to be used.

Deprecate the scl-pin and sda-pin properties in the devicetree.
Provide new scl-gpios and sda-gpios properties instead.
This lets the user specify SCL and SDA like this:
&i2c0 {
scl-gpios = <&gpio0 1 0>;
sda-gpios = <&gpio1 4 0>;
};
Instead of having to use:
&i2c0 {
scl-pin = <1>;
sda-pin = <36>;
};

Add some helper macros that will be convenient to use from device
drivers for accessing and error checking pin mux information in the
devicetree:
- NRF_DT_PSEL(): get a PSEL value out of the DT from either a
'foo-pin' or a 'foo-gpios' style property.
- NRF_DT_PSEL_CHECK_NOT_BOTH(), NRF_DT_PSEL_CHECK_EXACTLY_ONE():
helpers for checking that a given devicetree is OK according to
different criteria for setting PSEL properties (NAND or XOR on
whether the properties exist, respectively).

The current code is assuming that the SMC/HVC helpers can only be used
by the PSCI driver. This is wrong because a mechanism to call into the
secure monitor should be made available regardless of using PSCI or not.
For example several SoCs relies on SMC calls to read/write e-fuses,
retrieve the chip ID, control power domains, etc...
This patch introduces a new CONFIG_HAS_ARM_SMCCC symbol to enable the
SMC/HVC helpers support and export that to drivers that require it.
