properties are necessary to spetialize the driver to be used as a normal
16/32-bit counter or to provide the clock/calendar functions.

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Command "waitms 50" on ChromeBook EC console, then it will crash EC.
Because arch_busy_wait() is re-entried by two different tasks,
the second calling will reset the timer and may cause the first
calling to fail to reach the waiting destination
(if the first calling's wait time is longer enough).

Originally, when the timer's source clock is 32.768 kHz, the timer driver
uses two consecutive reads to ensure the timer reading is correct.
However, it is not robust enough due to an asynchronous timing issue in
the chip. The workaround is to add at least two NOPs between the
LDR and CMP instructions. This commit implements the workaround in the
assembly code to ensure it is not affected by the compiler toolchain
or optimization flags.

Add Zephyr support for the Audio DSP on the MT8196 SOC. This is a
very similar device to previous designs. Most of this patch is just
DTS.
The biggest delta is the more complicated second level interrupt
controller, though it is still able to be represented using some
vaguely clever DTS config over the older intc_mtk_adsp driver.
Also the memory layout is slightly different, requiring a little
indirection to set the initial boot stack address and log output
buffer. And the timer "irq_ack" register bits moved.

The timer count calculations are done with the assumption that the
prescalar is disabled. When using u-boot's SPL as an early boot stage,
the omap timer driver enables the prescalar leaving this driver to
calculate incorrect counts. So explicitly disable the prescalar to match
the driver expectation.

Timer driver using Microchip 32KHz based RTOS timer as the kernel
timer tick. The driver uses one of the 32-bit basic timers to
support the kernel's k_busy_wait API which is passed a wait
count in 1 us units. The 32-bit basic timer is selected by using
device tree chosen rtimer-busy-wait-timer set to the handle
of the desired 32-bit basic timer. If this driver is disabled,
the build system will select the ARM Cortex-M4 SysTick as the
kernel timer tick driver. The user should specify RTOS timer
as kernel tick by adding the compatible properity and setting
the status property to "okay" at the board or application level
device tree. The driver implements two internal API's for use
by the SoC PM. These two API's allow the SoC PM layer to disable
the timer used for k_busy_wait so the PLL can be disabled in
deep sleep. We used a custom API so we can disable this timer
in the deep sleep path when we know k_busy_wait will not be
called by other drivers or applications.

The new GRTC reading manner of the SYSCOUNTER uses hardware mechanism which
allows to keep it alive when any of CPUs is not sleeping. Otherwise
the SYSCOUNTER goes into sleep mode. Thus there is no
longer need to maintain the `CONFIG_NRF_GRTC_SLEEP_ALLOWED` symbol, however
if the user wants to have the SYSCOUNTER enabled all the time the
`CONFIG_NRF_GRTC_ALWAYS_ON` can be used instead.
The nrfx_grtc driver no longer provides the `wakeup-read-sleep` reading
manner.
Also setting the GRTC clock source is performed by the nrfx_grtc driver so
it has been removed from the `sys_clock_driver_init()` function.

The current driver implements the global defined "systick" interrupt
callback "sys_clock_isr" as a standard C function with an argument.
However, ARM's direct interrupt handlers do not have any arguments;
they must be declared as "void handler(void)".
Additionally, the direct handler should include some missing special
header/footer.
