(e.g. by muxing them to GPIO pins) It's often possible to control duty-cycle of such clocks which makes them suitable for generating PWM signal. allOf: - $ref: pwm.yaml# properties: compatible: const: clk-pwm clocks: description: Clock used to generate the signal. maxItems: 1 "#pwm-cells": const: 2 unevaluatedProperties: false required: - compatible - clocks examples: - | pwm { compatible = "clk-pwm"; #pwm-cells = <2>; clocks = <&gcc 0>; pinctrl-names = "default"; pinctrl-0 = <&pwm_clk_flash_default>; }; |
