4dc6927976 device: Remove DEV_* codes
This patch removes DEV_* codes from device.h since they are not used
anymore. All APIs now use error codes from errno.h, following the
conventions from doc/collaboration/code/error_code_conventions.rst.

6d1e3cf96d doc: power_mgmt: Added Power Management documentation
Documented the Power Management subsystem which includes the
power management hook interface, device power management,
device busy status interfac and other APIs. Also included
is a guide to writing Power Management applications.

This has 2 parts.  One is the general description of the
infrastructure and the PMA writing guide which goes in the
'subsystem' area. Other is the API description that gets
automatically pulled in from the comments in the source files.
The API description goes into the section where all other
Zephyr APIs are put.

f1b95df34e sensor: rename SENSOR_TYPE_* to SENSOR_VALUE_TYPE_*
Rename sensor_value_type enums from SENSOR_TYPE_* to more concludent
name SENSOR_VALUE_TYPE_*. This change is required if we want to
introduce SENSOR_TYPE_* (SENSOR_TYPE_ACCEL - if the sensor/driver
supports accelerometer, SENSOR_TYPE_MAGN - etc.) in the future.
Also it is more clear with this notation what these enums are referring
to.

1be6d1f6c8 sensor: add the posibility to fetch one data type
Now you can specify the sensor type you want to fetch using
sensor_sample_fetch_chan. This will inform the driver that you want only
one type of data updated, leaving the others unchanged and enabling
different sampling rates for multi function devices (MFDs).

fea1c49ba2 gpio: Improve the public API to handle multi callbacks
Many sub-systems might require to set a callback on different pins.
Thus enabling it via changing the API.

It is also possible to retrieve private-data in the callback handler
using CONTAINER_OF() macro (include/misc/util.h).

Former API is still available, and is emulated through the new one.
Using both should not be a problem as it's using new API calls.
However, it's now better to start using the new API.

592882e5f4 power_mgmt: APIs for devices to signal busy
Certain Low power SOC states (e.g. deep sleep)  will result in device
IP blocks losing state. In such a scenario it can be useful to have
a mechanism for devices (driver code) to signal the power manager /
policy that they are in the middle of a transaction.

We expect the device driver code to make a call to
device_busy_set(device *) before initiating a transaction and
device_busy_clear(device *) on completion. It is expected that device
driver developers will add this as necessary in their drivers.

Further an API is provided  for power manager application / policy to
check this. Based on this the power manager / policy can  decide
whether or not to go into a particular power state.

264c207f4f Bluetooth: Add custom "monitor" protocol logging over UART
With most boards there's no simple way to get access to the HCI
traffic. Simultaneously these boards only have one external UART for
the console. This patch introduces a protocol which combines both
normal logs and HCI logs over a single binary protocol sent over the
console UART.

The protocol is modeled based on the btsnoop/monitor protocols used by
BlueZ, and the first tool that's able to decode this is btmon from
BlueZ ("btmon --tty <tty>").

For platforms with two or more external UARTs it is still possible to
use CONFIG_UART_CONSOLE as long as the UART devices used are
different, however on platforms with a single external UART
UART_CONSOLE should be disabled if BLUETOOTH_DEBUG_MONITOR is enabled
(in this case printk/printf get encoded to the monitor protocol).

f703f7d0f6 debug: add target GDB server
The GDB server implements a set of GDB commands, such as read/write
memory, read/write registers, connect/detach, breakpoints, single-step,
continue. It is not OS-aware, and thus provides a 'system-level'
debugging environment, where the system stops when debugging (such as
handling a breakpoint or single-stepping).

It currently only works over a serial line, taking over the
uart_console. If target code prints over the console, the GDB server
intecepts them and does not send the characters directly over the serial
line, but rather wraps them in a packet handled by the GDB client.

This adds the DEVICE_AND_API_INIT() macro to take in a parameter
to assign to device->driver_api. This eliminates the need to
assign to driver_api during runtime device initialization.

This provides an alternative way to declare devices. This should
save a few bytes in ROM for those devices that will never fail
initialization (in other words, never need to manipulate
driver_api pointer at all).

Also clean up the documentation a bit to remove duplicated
block of information.

3257193c6d serial/uart.h: no need to check driver_api being NULL
The device_get_binding() no longer returns pointers
to device struct when driver_api is NULL. Therefore,
there is no need to check for driver_api being NULL
in the serial driver wrapper functions.

5aaf7ab930 nano_fifo: Fix problem with nano_fifo and timeouts
Fixes a problem where the nanokernel FIFO state information could get
out of sync due to a timeout.

The nanokernel FIFO structure nano_fifo now maintains two separate
queues: one for waiting fibers and the other for posted data. This
permits the safe and independent querying of the queues as needed
when getting and/or putting data from/on the nanokernel FIFO.

54425117d0 Bluetooth: Export helpers for defining buffer pools
Now that the incoming ACL & HCI event pools can be defined externally
to hci_core.c there should be convenience macros to know what's the
minimum required buffer size for these pools.

30601c09bb Bluetooth: Refactor buffer handling for non-host managed buffers
So far the assumption has been that the host stack manages all
incoming and outgoing buffers. For the incoming buffers (from the
controller) this has required hci_core.c to manage its own pools and
do the host flow control. This setup makes perfect sense for an
architecture where the controller resides remotely on a different CPU
& address space (i.e. the "traditional" HCI transport case).

When the stack runs on a system where the controller resides in the
same address space this setup doesn't work that well. In such a
scenario the incoming buffers are ideally created as low down in the
stack as possible (i.e. below HCI), which means that the current
hci_core.c cannot be responsible for managing their pools.

To allow for both types of architectures this patch introduces a new
BLUETOOTH_HOST_BUFFERS Kconfig option that can be selected to say that
host-side management is desired, or deselected to say that the
controller (residing in the same address space) takes care of managing
the incoming buffers.

So far the incoming buffer types were identified by hci_core.c by
looking at their "free pool" pointers, however as soon as the pools
are allowed to be somewhere else this doesn't work. To solve this we
now require a minimum user data size for all Bluetooth buffers and use
that to store the buffer type.

a1adbcb125 ieee802154: Replace the CC2520 driver with a new implementation
This is a complete new cc2520 driver for zephyr. Intention is to fit
better within Zephyr device driver model.

- It's (almost*) ready to be instanciated as many times as necessary
- It's fully interrupt based on SFD and FIFOP (no pin polling)
- It's nicer to other sub-systems (it sleeps, no busy-wait loop)
- It still loosely complies to old legacy radio device driver model

*: GPIO API needs to be fixed in order to accept multiple callbacks, as
well as enabling callbacks to retrieve private data.

Notes:
- Hardware filtering does not work yet as the net stack, above, needs to
  provide the relevant information for it (src/dst ieee802154 extended
  addresses, short addresses...)
- A embryo of generic functions (txpower, channel, addresses...)
  have been implemented but don't belong yet to any radio device driver
  model. Such new driver model will come afterwards (soon?)
- SPI API would need to be improved to avoid as much as possible memcpy
  as well as spi_slave_select() call.
