Andy Gross 82cf7d0918 dts: arm: Kinetis: Add support for Hexiwear K64
This patch adds DTS support for the Hexiwear K64 platform.  This
includes enabling the DTS config option and adding conditionals around
the options to be replaced.

In addition, a DTS file is provided that customizes the Kinetis
platform to match the hexiwear board.  A fixup file is provided to map
the generated information to the current client driver usage.  This
file is temporary.

Andy Gross 4192dcc6bc dts: arm: Kinetis: Add FRDM_K64F support
This patch adds DTS support for the FRDM_K64F board.  The defconfig
enables the DTS usage and the FRDM K64F specific DTS file provides the
differences from the base Kinetis DTS definitions.

A fixup file is provided to map the generated configuration information
to the driver consumers.  The fixup file will be removed once the
drivers are modified to handle the newly generated information.

Andy Gross ddce7dea40 dts: arm: Kinetis: Add base support for Kinetis
This patch adds DTS support and related files for the NXP Kinetis
platform.  The DTS files contain the base definitions for the hardware
nodes on Kinetis platforms.  The YAML files provide the definitions of
the contents of the DTS nodes.

The Kconfig changes were put in place to allow for the conversion of
existing drivers.  Once those drivers are modified, the Kconfig options
that are replaced by the DTS information will be removed.

Andy Gross 3979eb44ad dts: arm: Add base DTS and YAML definitions
This patch adds the base DTS and YAML files that may be referenced by
SoCs.  The device tree files provide base definitions for the more well
known ARMV7M device nodes.  These files are meant to be included in
SoC vendor specific device tree files.

The YAML files provide definitions for the contents of device tree node
that contain information that will be parsed and used for configuration
in the system.

DTS files define hardware and software configuration and YAML files
provide the markers for knowing which pieces need to be extracted.

Andy Gross bb063164aa dts: Add support for Device Tree
This patch adds support for using device tree configuration files for
configuring ARM platforms.

In this patch, only the FLASH_SIZE, SRAM_SIZE, NUM_IRQS, and
NUM_IRQ_PRIO_BITS were removed from the Kconfig options.  A minimal set
of options were removed so that it would be easier to work through the
plumbing of the build system.

It should be noted that the host system must provide access to the
device tree compiler (DTC).  The DTC can usually be installed on host
systems through distribution packages or by downloading and compiling
from https://git.kernel.org/pub/scm/utils/dtc/dtc.git

This patch also requires the Python yaml package.

This change implements parts of each of the following Jira:

Johan Hedberg 6c995a5053 Bluetooth: Fix missing connection cleanup in some scenarios
If the TX thread is not in k_poll() when conn->state gets set to
DISCONNECTED and a dummy buffer is pushed to conn->tx_queue the
bt_conn_prepare_events() function would have failed to add the
connection to the poll list for cleanup. To ensure the cleanup always
happens introduce a new flag that indicates that a cleanup must
happen. The extra benefit of the flag is that we no-longer need a
dummy buffer, but can simply use the conn_change signal to wake up the
TX thread.

Szymon Janc fb3317b7a1 Bluetooth: Fix not clearing signaled flag for conn_change signal
From k_poll_signal_init() documentation:
The poll signal contains a 'signaled' field that, when set by
k_poll_signal(), stays set until the user sets it back to 0. It thus
has to be reset by the user before being passed again to k_poll() or
k_poll() will consider it being signaled, and will return immediately.

Benjamin Walsh 2014ff162e kernel/poll: fix registrations that were not always cleared
Poll events were getting registered even when polling conditions had
already been met, but events with conditions met did not register and
did not increment the number of events registered. This caused a
possible discrepancy between the number of events registered and the
position of the last event registered in the events array.

As soon as one event condition is met, the next ones in the array should
not get registered even if their condition is not met. This is what the
code does now.

Marcus Shawcroft 878aa5f15c net/dhcpv4: Correct backoff and retransmit behaviour
Implement RFC2131 4.1.1 requirement that at dhcp implementation wait
for a random delay of 1 to 10s before sending the initial DISCOVER.

Implement RF2131 4.1 requirement that at dhcp implementation set the
initial retransmit timeout at 4 seconds and exponentially backoff on
each retransmit.

Marcus Shawcroft d06ca47eb3 net/dhcpv4: Use unique XID on each request.
Rather than reuse XID's on retransmissions, always use a unique XID.

Either behaviour is permitted by rfc2131.  Debugging the dhcp client
in the presence of multiple dhcp servers with significant packet loss
in the network is much easier if we don't unnecessarily reuse request
identifiers.
