Additional optional properties:



Some devices may support additional optional properties to help with, e.g.,

power sequencing. The following properties can be supported by one or more

device-specific compatible properties, which should be used in addition to the

"hid-over-i2c" string.



- compatible:

  * "wacom,w9013" (Wacom W9013 digitizer). Supports:

    - vdd-supply

    - post-power-on-delay-ms



- vdd-supply: phandle of the regulator that provides the supply voltage.

- post-power-on-delay-ms: time required by the device after enabling its regulators

  before it is ready for communication. Must be used with 'vdd-supply'.



Example:
