e362f10d4c drivers: pwm: add a SAM0 TCC based PWM driver
This runs the Timer/Counter for Control in 'normal' PWM mode.  The
number of channels and counter width depends on the device and is
imported from DeviceTree.

f4c36b7beb drivers: pwm: add driver for NXP Kinetis TPM module
The TPM (Timer/PWM Module) is a 2- to 8-channel timer which supports
input capture, output compare, and the generation of PWM signals to
control electric motor and power management applications.

This patch adds the driver and the binding necessary for instantiating
the driver. The work is based on the RV32M1 driver for TPM done by
Henrik Brix Andersen. A later patch will enable this driver to be used
for the KW41Z SoC, if PWM support is requested.

56db098a55 drivers: pwm: Add driver for LiteX PWM peripherial
PWM driver for LiteX SoC builder was created.
Because LiteX supports only one channel for each PWM device,
an appropriate restriction was made.

3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier
Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier.  Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.

By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

1dc3cc7fc6 drivers/pwm: Driver for SiFive PWM peripheral
The PWM driver can only control channels 1-3 of the PWM peripheral, not
channel 0. This is an artifact of the peripheral's design.

2168d80987 drivers: add Atmel SAM PWM driver
This patch adds basic support for the PWM devices available on the Atmel
SAM family. Beside enabling the driver, everything is selected through
the device tree, including enabling the PWM0 and PWM1 devices. Thus
CONFIG_PWM_0 and CONFIG_PWM_1 are ignored.

b0db28b512 drivers: Cmake: Add __ZEPHYR_SUPERVISOR__ macro for driver files.
Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.

In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

12f8f76165 Introduce cmake-based rewrite of KBuild
Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.

Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.

This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.

For users that just want to continue their work with minimal
disruption the following should suffice:

Install CMake 3.8.2+

Port any out-of-tree Makefiles to CMake.

Learn the absolute minimum about the new command line interface:

$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..

$ cd build
$ make
