Andreas Sandberg ba330ec765 drivers: lora: Prepare Kconfig for additional radios
Add a new configuration option, LORA_SX12XX, that is shared for all of
the LoRaMAC-node-based radio drivers. By default, the appropriate
driver for the LoRa radio in the device tree is included is included
in the build.

Marcin Niestroj 51666b8130 lora: select REQUIRES_FULL_LIBC when LORA=y
Right now we depend on NEWLIB_LIBC to build Zephyr with LORA=y. This
seems to be the only Kconfig option like that. Convert it to select
REQUIRES_FULL_LIBC instead, which will select NEWLIB_LIBC by default and
allow to use external libc as well.

Anas Nashif ee985d81aa shell: enable modules by default if shell is enabled
If shell is enabled then enable all sub-shells if their dependencies are
satisfied. This was done for some modules and subsystems but was not
consistent.

Andreas Sandberg d8de33e966 drivers: lora: Add a shell for LoRa testing
Provide basic commands that are useful when testing a LoRa
radio. Currently, the shell supports:

> lora conf ...
> lora send ...
> lora recv ...
> lora test_cw ...

Manivannan Sadhasivam 7be8debaab lora: Switch to new timeout API
Get rid of legacy timeout API and move to new timeout API for LoRa.
This involves changes to API, SX1276 driver and sample application.

Manivannan Sadhasivam 0f02adfb0e lora: Make the LoRa support Experimental
The LoRa APIs are expected to undergo some change as the usecase get's
increased. So let's mark it as experimental until the APIs got
stabililized.

Andy Ross 7832738ae9 kernel/timeout: Make timeout arguments an opaque type
Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument.  Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created.  This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.

The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.

The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.

Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.

For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided.  When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.

Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions.  These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig.  These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.

k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.

Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate.  Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure.  But k_poll() does not fail
spuriously, so the loop was removed.

Alexander Wachter f590d4fadb drivers: lora: build with newlib
The loramac-node library uses math functions from math.h that
are not included in the minimal lib.
This commit changes the samples project config to always build
with newlib and adds a dependency to newlib.
