dt-bindings: pwm: samsung: Do not require interrupts on Exynos SoCs (c46ed28d) · Commits · 戴 / test

The bindings required interrupts for all SoCs but actually only the PWM timer clocksource (for S3C/S5P SoCs) was using them. This PWM timer clocksource driver is not used on Exynos SoCs thus the interrupts can be marked as optional. Reported-by:
