Subject: [PATCH v4 5/10] dt-bindings: pwm: add a property "num-pwms"
Date: Tue, 20 Aug 2019 09:40:20 +0800 [thread overview]
Message-ID: <1566265225-27452-6-git-send-email-sam.shih@mediatek.com> (raw)
In-Reply-To: <1566265225-27452-1-git-send-email-sam.shih@mediatek.com>
From: Ryder Lee <ryder.lee@mediatek.com>
This adds a property "num-pwms" in example so that we could
specify the number of PWM channels via device tree.
