This simplifies the "depends on" since we don't need DM_PWM listed
explicitly there as it already is made explicit via the surrounding
"if". No intended change in behavior.

Since it is registered as a U_CLASS_DRIVER, Sandbox PWM driver is a
Driver Model Driver and thus to be usable depends on DM_PWM to be
selected.

Let's make sure of that via the appropriate Kconfig option.

So it's visually better split from the other subsystems when using
menuconfig.

A few pwm drivers cannot build without access to some platform
specific header files. Express those requirements in Kconfig as well.

In am33xx SoC[1], enhanced capture (eCAP) supports auxiliary PWM (APWM).
This series adds the PWM driver support for the APWM feature for eCAP on
AM33xx.

eCAP HW also supports the capture mode. Currently, this driver only
supports APWM.

This is based on the Linux kernel driver -> drivers/pwm/pwm-tiecap.c
Version: v6.12

Tested on AM335x EVM[2].

Add driver to support pwm on STM32MP1X SoCs. The PWM signal is generated
using a multifuntion timer which provide a pwm feature. Clock rate and
addresses are retrieved from the multifunction timer driver.

To work correctly, this driver depends on SYSCON to get the base address
from the parent dts node.

We rename the S5P specific "CONFIG_PWM" to CONFIG_PWM_S5P and move it to
Kconfig.  Given the usage of CONFIG_PWM_NX, we have that select this new
symbol.

TTC has three modes of operations. Timer, PWM and input counters.

There is already driver for timer under CADENCE_TTC_TIMER which is used for
ZynqMP R5 configuration.
This driver is targeting PWM which is for example configuration which can
be used for fan control.
The driver has been tested on Xilinx Kria SOM platform where fan is
connected to one PL pin. When TTC output is connected via EMIO to PL pin
TTC pwm can be configured and tested for example like this:
pwm config 0 0 10000 1200
pwm enable 0 0
pwm config 0 0 10000 1400
pwm config 0 0 10000 1600
