    Subject[PATCH v4 1/4] dt-bindings: input: cirrus,cs40l50: Add initial DT binding
    Date
    From: James Ogletree <james.ogletree@cirrus.com>

    The CS40L50 is a haptic driver with waveform memory,
    integrated DSP, and closed-loop algorithms.

    Add a YAML DT binding document for this device.
