Removing period, duty and polarity configuration from
channel devicetree. At boot time, only minimal setup like
pinctrl, prescaler, etc should be initialized. PWM signal
is produced by using pwm_set* API
Also after this change, PWM period, duty are changed at the
next counter period boundary

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Allow configuring the clock prescaler divider for the NXP Kinetis
Timer/PWM Module (TPM). Setting the prescaler to a lower value
allows for higher resolution for the generated PWM waveforms.
This change is inspired from the pwm_mcux_ftm driver:

If the `divider-int-0` or variations of these for each channel properties
are not specified, or if these is 0,
the driver dynamically configures the division ratio by specified cycles.
The driver will operate at the specified division ratio if a non-zero
value is specified for `divider-int-0`.
This is unchanged from previous behavior.
Please specify ``divider-int-0`` explicitly to make the same behavior as
before.
In addition, the default device tree properties related to the division
ratio have been removed.

FTM internal counter can be clocked by one of three clock sources
independent of the module bus clock. This patch introduces a DT property
to perform the clock selection from DT.
DT sources are updated to keep the current clock selection for all boards,
with exception of ucans32k1sic board which is migrated to use system
clock by default, as this seems to be a better choice for most cases.
Some PWM LED samples require slower clock so overlays are added for
those cases.

This prepares support pwm capture APIs by extended current pwm
shim driver but use a differrence hal component:
- Introduce a Kconfig options that will be set when PWM pulse
generation API is used, it is also used to select the hal
component. Guarding current code inside this Kconfig option
- Increase #pwm-cells to 3, flags is supported for PWM capture
- Do not require duty-cycle and polarity be set in dt, PWM
capture doesn't need it.
- Rename emum value for pwm-mode to keep only key information
- Add preprocessor in case no channel is configured for generate
PWM output, to avoid warning when build

Previously the pwm capture only support capturing on channel 1
and 2, because the slave mode controller was used, which uses
the signal TIxFP which is not available for channel 3 and 4.
This commit adds optional support for four channel capturing by
changing the method of capturing PWM signals to not use the
slave mode controller to reset the counter register. Instead the
counter is reset in the ISR. This will result in a slight loss
of accuracy but is still within an acceptable range.

This introduces PWM driver with supporting PWM output
APIs based on NXP S32 EMIOS peripheral. This supports
three mode: OPWFMB, OPWMCB and OPWMB.
OPWFMB uses internal counter, the new period and duty
cycle takes effect immediately.
OPWMCB and OPWMB use external counter as timebase, changing
PWM period at runtime will impact to all channels share the
same timebase. Also the new period and duty cycle take effect
in next period boundary of the timebase

Adds driver for pwm on xmc4xxx using Capture Compare Unit 8 (CCU8)
module. There are two CCU8 nodes with each one having four slices.
Each slice has two output channels.
Unlike CCU4, this module can generate complementary high-side/low-side
signals for each output channel. A variable dead time can be added
during the off to on transitions to make sure that the
high-side/low-side signals are not on at the same time.

Adds driver for pwm on xmc4xxx using Capture Compare Unit 4 (CCU4)
module. There are four CCU4 with each one having four channels
Thus it's possible to have up to 16 pwm output signals. The output of
each channel can only be connected to a specific port/pin. The possible
connection and gpio configurations are defined using pinctrl.
The CCU4 module also has a capture mode. Capture support will be added
