If timeout is being overwrite exactly when previous one is expiring
then hardware event was cleared correctly but interrupt was already
triggered. Interrupt routine was assuming that compare event is set
and proceed with that assumption. However, in that corner case when
compare event was overwritten and event was cleared, that was not the
case.
As the outcome, timeout could be triggered prematurely. Fixed by
clearing pending interrupt after handling previous compare value.

mcuboot and possibly other tools read single byte values to determine
the state of objects. Rather than fail to do the read of values too
short for this peripheral detect the situation and read into a stack
buffer that meets the length criteria, and on success copy the data
into the provided buffer.

* still need to clear IP bit in timer irq handler
* last_time should be aligned to ticks, old code will miss some
cycles which are about (curret_time - last_time) % CYC_PER_TICK
* in timeout set, shorten the delay needed when tick is 0, this
will improve the response of timer irq

the pulse triggered timer irq doesn't work for all targets. In
iotdk, we found the clear of IP bit will clear int request
when elapsed called in thread context. So come back to level
triggered way which is supported in all targets, and use the sw
triggered irq to remember the irq request which may be cleared
in non timer int handler.

When PCIe is enabled for UART, the port address is probed during
initialization and is written back into the device config struct.
However, the device config struct is supposed to be const and
read only. This results in page faults when MMU is enabled as
the struct cannot be written into. So fix this by storing port
address in device data struct if a particular UART instance is
of PCIE.

The init function returns successful even if the first

Some kernel tests use `CONFIG_TICKLESS_KERNEL=n` with

All initialization of the Ethernet interface is done in the
eth_initialize function which is invoked by the boot code.
This function sets up DMA, programs the Ethernet module and
enables IRQs. However, this function does not setup "netif"
interface info which is done when the ethernet device is
enumerated by the NET stack via the "iface_api.init" func.
However, after the eth_initialize func is called, it is
possible that the system receives RX interrupts, and the
"rx_thread" accesses the "netif" pointer to get iface info.
However, because the "netif" info is not necessarily
populated at this time, we get a crash (as OS does NULL
access).
Fixed by enabling Ethernet IRQ after the interface is
properly setup.
Tested on Nucleo F767Zi board.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.

Move from a Kconfig to select/initialize the MAC address to using the

either a driver specific means or by the setting of
"zephyr,random-mac-address" in the devicetree.
