drivers: pwm: add pwm driver support in NPCX7 series In npcx7 series, there're 8 Pulse Width Modulator (PWM) modules and each one support generating a single 16-bit PWM output. A 16-bit clock prescaler (PRSCn) and a 16-bit counter (CTRn) determine the cycle time, the minimal possible pulse width, and the duty-cycle steps. Beside introducing pwm driver for Nuvoton NPCX series, this CL also includes: 1. Add PWM device tree declarations. 2. Zephyr PWM api implementation. 3. Add aliases in npcx7m6fb_evb board device tree file for supporting samples/basic/blinky_pwm application and pwm test suites Signed-off-by: Mulin Chao <MLChao@nuvoton.com>

drivers: pwm: Update drivers to use devicetree Kconfig symbol Update pwm drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

help
This option enables the PWM driver for NPCX family of
processors.
Say y if you wish to use pwm ports on NPCX MCU.
