From c46ed28dbe95844c1d15addd26ff05499057c4d5 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 2 Jul 2020 17:51:42 +0200 Subject: [PATCH] dt-bindings: pwm: samsung: Do not require interrupts on Exynos SoCs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
