Kumar Gala cc334c7273 Convert remaining code to using newly introduced integer sized types
Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.  This handles the remaining includes and kernel, plus
touching up various points that we skipped because of include
dependancies.  We also convert the PRI printf formatters in the arch
code over to normal formatters.

Kumar Gala 789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Baohong Liu 56e0b53c6e drivers: pwm: re-design pwm API interfaces
Re-design the pwm API interfaces. A RFC was sent and discussed
recently on the re-design of PWM APIs.

APIs like pwm_pin_set_values, pwm_pin_set_period, pwm_pin
_set_duty_cycle will be deprecated and replaced by the new
APIs pwm_pin_set_cycles and pwm_pin_set_usec.

A new API pwm_get_cycles_per_sec will be added to get the
clock rate for pwm pins.

The API pwm_pin_set_phase will be deprecated(it always sets
the phase to zero).

The API pwm_pin_configure will be deprecated since it is not
doing anything for most of the platforms or it can be moved
to device init function for the other platforms.

All the pwm_all_xxx APIs will be deprecated. If necessary,
user or an app can set the pins individually.

Baohong Liu 9cfed4940c drivers: pwm_shim: correct api argument inconsistency
Correct the argument definition inconsistency for the set
value API. To be consistent with other pwm sub drivers, the
on and off arguments for the set value api are re-defined.

On: how far (number of timer count) from the beginning of a PWM
    cycle the PWM pin will be asserted.
Off:how far (number of timer count) from the beginning of a PWM
    cycle the PWM pin will be de-asserted.

Andre Guedes 245e140da6 drivers: Replace DEV_INVALID_OP by -ENOTSUP
This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.

This patch is part of the effort to transition from DEV_* codes to
errno.h codes.
