At this point, if the frame was accepted by the controller, it means
that CRC was valid. Thus, there is no reason to get it in the buffer.

f2c1b4bb02 drivers: bmi160: use direct GPIO trigger instead of IPM
Directly use AON GPIO trigger instead of IPM.

In the past, SW did not allow arc to receive AON GPIO interrupt.
So, interrupt from BMI160 was routed to x86 cpu. Then, x86 cpu
passed the event to arc through IPM. But, SW was updated and arc
is able to directly receive interrupt from AON GPIO now. So, IPM
is not needed any more. Let's remove IPM related code and use
GPIO as the default trigger source.

This change is on top of the bmi160 sample app change to not use
IPM.

ca0951d42d drivers: timer: Optimize RTC driver and prevent past events
The nRF RTC driver, which is used a system clock driver due to the lack
of SysTick hardware on the SoC, was using too much CPU time in its
_timer_idle_exit() implementation due to the use of 64-bit arithmetical
operations. This was causing the ISR wrapper to add excessive latency to
critical interrupts, causing BLE controller asserts.
This patch addresses the issue by using exclusively RTC ticks instead of
OS ticks, thus avoiding the necessity to convert during
_timer_idle_exit() calls, which are the most critical to interrupt
latency.

In addition the driver is now able to detect setting tick events in the
past due to it being interrupted by a higher priority context, and will
reschedule and trigger the ISR at the same time.

cd8504cc9c arcv2_irq: Add power management suspend/resume
In order to resume the ARC from deep sleep,
the interrupts need to be restored.

The FIRQ stack needs to be saved and restored
when performing sleep operations.

During early initialization, the sp in the 2nd register bank
is made to refer to _firq_stack.
This allows for the FIRQ handler to use its own stack.
Fast Interrupts cannot be used after sleep if this information
is not restored.

This patch adds the suspend and resume functions.

71c7c01819 net: buf: Remove the need for net_buf_pool_init()
In order to keep the initialization process light-weight, remove
net_buf_pool_init() and instead perform the initialization of the pool
and buffers in a "lazy" manner. This means storing more information
in the pool, and removing any 'const' members from net_buf. Since
there are no more const members in net_buf the buffer array can be
declared with __noinit, which further reduces initialization overhead.

954baea90b random: Restructure RANDOM Kconfig
Restructure the RANDOM Kconfig to match the structure used in other
drivers with a single top level menu.  Move the true random number
generators to appear first in the menu, with pseudo generators at the
bottom.  Do not present pseudo generators if a true random generator
is presented.

This change implies that tests, samples and applications that require
the random driver interface must now select CONFIG_RANDOM_GENERATOR.

In order for tests and samples to build (and run) on platforms that
have no random driver it remains necessary to select
the CONFIG_TEST_RANDOM_GENERATOR.

Note that CONFIG_TEST_RANDOM_GENERATOR retains its original purpose of
enabling a random driver that delivers non random numbers for the
purpose of testing only.

c3e08c8fea net: buf: Redesigned pool & buffer allocation API
Until now it has been necessary to separately define a k_fifo and
an array of buffers when creating net_buf pools. This has been a bit
of an inconvenience as well as blurred the line of what exactly
constitutes the "pool".

This patch removes the NET_BUF_POOL() macro and replaces it with a
NET_BUF_POOL_DEFINE() macro that internally expands into the buffer
array and new net_buf_pool struct with a given name:

	NET_BUF_POOL_DEFINE(pool_name, ...);

Having a dedicated context struct for the pool has the added benefit
that we can start moving there net_buf members that have the same
value for all buffers from the same pool. The first such member that
gets moved is the destroy callback, thus shrinking net_buf by four
bytes. Another potential candidate is the user_data_size, however
right not that's left out since it would just leave 2 bytes of padding
in net_buf (i.e. not influence its size). Another common value is
buf->size, however that one is also used by net_buf_simple and can
therefore not be moved.

This patch also splits getting buffers from a FIFO and allocating a
new buffer from a pool into two separate APIs: net_buf_get and
net_buf_alloc, thus simplifying the APIs and their usage. There is no
separate 'reserve_head' parameter anymore when allocating, rather the
user is expected to call net_buf_reserve() afterwards if something
else than 0 headroom is desired.

The existing explicit sys_rand32_init() function runs immediately after
PRE_KERNEL_2 before stack canaries are initialized.  In order to get
equivalent behaviour with sys_rand32_init() we set SYS_INIT() to
initialize the random drivers at the lowest priority of PRE_KERNEL_2.

a4e823eee0 pinmux: Introduce new ksdk pinmux driver
Kinetis SoCs contain one or more PORT modules to handle pin muxing and
pin configuration. Unlike the existing k64 pinmux driver, this driver
handles each PORT module individually and can be used for other Kinetis
SoCs.

This driver uses KSDK CMSIS register accesses to the PORT module rather
than the KSDK PORT driver (fsl_port.h), because the Zephyr pinmux
interface contains both set() and get() functions to access the pin
configuration. The KSDK PORT driver only contains a set() function
(which is a very thin static inline function to modify the PCR
register), therefore building a shim on top of it would result in a
strange mix of using the KSDK PORT driver for the set() and a direct
CMSIS register access for the get().

2fcf3435c1 serial: Provide new numbering scheme for stm32 UART

This commit allows to align "UART_1" to IP USART_1.
Change is propagated to all STM32F103RB/STM32F401RE based boards and

212f5f28ed drivers: spi_k64: Fix RX overflow
This patch fixes RX overflow error in the k64 SPI driver.

Jira: ZEP-1351
Jira: ZEP-1352

Several circumstances lead to an RX overflow:

The RFOF_RE (RX fifo overflow) must not be set as default.
The flag is only set when rx_buf is available. Also it must
be checked inside spi_k64_isr whether RFOF_RE has been set or not.

If the rx_buf is not available and the incoming data
should be ignored, then MCR_ROOE need to be set.
Since it is not possible to change the MCR register
during the transfer, RX fifo must be emptied
if rx_buf_len < tx_buf_len.

The driver also uses spi_data.xfer_len now,
the variable was already defined. Now, transfers are also
possible if tx_buf_len < rx_buf_len (e.g. read slave device register).
spi_k64_push_data has been adjusted accordingly.

The patch simplifies the handling of interrupts.
The interrupts are also switched off in the event of an error.

The patch also fixes a few coding style issues.

The 802.15.4 frame has a header and in the end after the payload a CRC.
Overall MTU is 127 bytes, but CRC is most likely going to be generated
by the device itself (offloading). Because the limitation of current
nbuf, it's not possible to keep this CRC in the buffer because it
require a user data size of 127 bytes but if we do so, IP stack will
fill in as much as it can as packet data, thus occupying the 2 last
bytes. This generates bugs. A perfect solution would be to generalize a
better handling of MTU and head or tail reserve data into nbuf, but
this will probably be solved in the future.

aa54086dc6 drivers: ieee802154: Fix some old left-over before multi-frag support
And take the opportunity to reduce the buffer size, as 127 is the 15.4
MTU, it has just engouh space on 128 bytes for the spi cmd plus the
frame.

9313172f84 drivers: ieee802154: Let's timeout on cc2520 tx
Looks like getting an SFD interruption is not 100% reliable, so let's
just use a semaphore with a timeout on it instead of using
device_sync* routines.

d33c883eaf drivers: ieee802154: Rework RX buffer handling in cc2520
Flushing rxfifo is necessary only on complete failure. It's badly
documented, but cc2520 errata mention that srxflush instruction should
be avoided as much as possible because it generates garbage in rxfifo
and kills incoming rx packet.

f8ec175aa7 drivers: ieee802154: Fix length handling in uart-pipe
15.4 drivers are supposed to append LQI byte in the end of the buffer,
but of course there is no such thing in uart-pipe. Thus the bug, so
let's announce the proper length even if such LQI is missing.
Also align the debug output to proper length (FCS included)

ad064e1434 eth: ksdk: Protect Ethernet frame buffer operations with IRQ lock.
As there's a single intermediate frame buffer used by both RX and TX
routines, protect operations on it with irq_lock() to avoid possibility
that it will be concurrently modified.
