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.

e2346cf6a2 drivers: pwm: mcux_ftm: add support for inverted polarity pwm signals
Add support for specifying the PWM signal polarity through flags to
the NXP Kinetis FlexTimer (FTM) PWM driver.

Prior to this change the FTM PWM driver always produced inverted
polarity (active-low) PWM signals.

db611e6781 drivers: pwm: add support for inverted PWM signals
Add support for requesting an inverted PWM pulse (active-low) when
setting up the period and pulse width of a PWM pin. This is useful
when driving external, active-low circuitry (e.g. an LED) with a PWM
signal.

All in-tree PWM drivers is updated to match the new API signature, but
no driver support for inverted PWM signals is added yet.

All in-tree PWM consumers are updated to pass a flags value of 0
(0 meaning default, which is normal PWM polarity).

Fixes #21384.

b1d5eed262 drivers: nrfx: Update implementations after switching to nrfx 2.0.0
Update calls to nrfx HAL functions to reflect API changes introduced in
nrfx 2.0.0. All these functions are now called with the first parameter
pointing to the structure of registers of the relevant peripheral.
Also a few functions got renamed:
- nrf_gpiote_int_is_enabled to nrf_gpiote_int_enable_check
- nrf_gpiote_event_is_set to nrf_gpiote_event_check
- nrf_rng_event_get to nrf_rng_event_check
- nrf_rng_int_get to nrf_rng_int_enable_check
- nrf_rtc_event_pending to nrf_rtc_event_check
- nrf_rtc_int_is_enabled to nrf_rtc_int_enable_check
- nrf_timer_cc_read to nrf_timer_cc_get
- nrf_timer_cc_write to nrf_timer_cc_set

Default configuration values were removed from nrfx_config files,
so the drivers pwm_nrfx and spi_nrfx_spis no longer can use those.

Function nrfx_pwm_init() now takes one more parameter - context pointer
that is passed to the event handler, not used in the pwm_nrfx driver.

HALs for UART and UARTE now allow configuration of the parity type
and the number of stop bits, for SoCs that provide the corresponding
registers.

677f1e6db9 kconfig: Turn pointless/confusing 'menuconfig's into 'config's
Defining a symbol with 'menuconfig' just tells the menuconfig to display
any dependent symbols that immediately follow it in a separate menu.
'menuconfig' has no effect on symbol values.

Making a symbol that doesn't have any dependent symbols after it a
'menuconfig' should be avoided, because then you end up with an empty
menu, which is shown as e.g.

    [*] Enable foo ---

This is how it would be shown if there were children but they all
happened to be invisible as well.

With a regular 'config', it turns into

    [*] Enable foo

Change all pointless 'menuconfig's to 'config's.

See the section on 'menuconfig' on the Kconfig - Tips and Best Practices
page as well.

5239bef610 drivers: pwm_nrf5_sw: Remove PWM_NRF5_SW_0_DEV_NAME Kconfig option
This option determines the name under which the device represented by
the `sw_pwm` node is registered in the system. But when the value of
this option does not match the `label` property of the `sw_pwm` node,
a problem arises when the `sw_pwm` node is referenced by a "pwm-leds"
compatible node, since the `*_PWMS_CONTROLLER` macro that is generated
for this referencing node contains a non-existing device name (as it is
the `label` property value, not the Kconfig option value).
This commit solves the issue described above by removing the Kconfig
option and replacing all of its occurrences in sample applications
by the standard macro generated for the `sw_pwm` node, containing
the value of the `label` property of this node.
