We need to enable this regulator before the digitizer can be used. Wacom recommended waiting for 100 ms before talking to the HID.

according to the hid-over-i2c binding, this should use a special compatible like compatible = "wacom,w9013", "hid-over-i2c" As the binding patch is from Caesar, I assume that is the Kevin component and I can add that myself, just need confirmation that this is actually the correct component :-) . Thanks Heiko
