Subject: [PATCH v6 5/7] dt-bindings: pwm: pca9685: Add nxp,staggered-outputs property
Date: Mon, 29 Mar 2021 14:57:05 +0200 [thread overview]
Message-ID: <20210329125707.182732-5-clemens.gruber@pqgruber.com> (raw)
In-Reply-To: <20210329125707.182732-1-clemens.gruber@pqgruber.com>
The pca9685 driver supports a new nxp,staggered-outputs property for
reduced current surges and EMI. This adds documentation for the new DT
property.
