Subject: [PATCH v4 4/4] dt-bindings: pwm: pca9685: Add nxp,staggered-outputs property
Date: Mon, 7 Dec 2020 20:38:10 +0100 [thread overview]
Message-ID: <20201207193810.493299-1-clemens.gruber@pqgruber.com> (raw)
In-Reply-To: <20201207193629.493241-1-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.
