Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig.

drivers/timer/apic_timer.c: new local APIC timer for TICKLESS_KERNEL The existing local APIC timer driver (loapic_timer.c) has bitrotted and doesn't support TICKLESS_KERNEL, which is the preferred mode of operation. This patch introduces a completely new driver, called the APIC timer driver - the name is changed to allow the drivers to continue to coexist in the short term, and also because "APIC timer" isn't ambiguous (the I/O APICs do not have timers). This driver makes no attempt to work with the MVIC timer as the previous version did, because MVIC support is deprecated. Signed-off-by: Charles E. Youse <charles.youse@intel.com>

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kernel/timeout: Remove "clock_always_on", replace with "SLOPPY_IDLE" This is an oddball API. It's untested. In fact testing its proper behavior requires very elaborate automation (you need a device outside the Zephyr hardware to measure real world time, and a mechanism for getting the device into and out of idle without using the timer driver). And this makes for needless difficulty managing code coverage metrics. It was always just a hint anyway. Mark the old API deprecated and replace it with a kconfig tunable. The effect of that is just to change the timeout value passed to the timer driver, where we can manage code coverage metrics more easily (only one driver cares to actually support this feature anyway).

config SYSTEM_CLOCK_SLOPPY_IDLE
bool "Timer allowed to skew uptime clock during idle"
help
When true, the timer driver is not required to maintain a
correct system uptime count when the system enters idle.
Some platforms may take advantage of this to reduce the
overhead from regular interrupts required to handle counter
wraparound conditions.
clock: Make sure the clock is initialized prior to devices On NANOKERNEL level only of course. Some devices, initialized at this level, may require to get the clock running already.

This options can be used to set a specific initialization priority
value for the system clock driver. As driver initialization might need
the clock to be running already, you should let the default value as it
is (0).
