Subject: [PATCH] dt-bindings: pwm: pca9685: Add staggered-outputs property
Date: Wed, 18 Nov 2020 18:45:15 +0100 [thread overview]
Message-ID: <20201118174515.278067-1-clemens.gruber@pqgruber.com> (raw)
The pca9685 driver supports a new staggered-outputs property for reduced
current surges and EMI. This adds documentation for the new DT property.
