+* QNAP Power Off
+
+QNAP NAS devices have a microcontroller controlling the main power
+supply. This microcontroller is connected to UART1 of the Kirkwood and
+Orion5x SoCs. Sending the charactor 'A', at 19200 baud, tells the
+microcontroller to turn the power off. This driver adds a handler to
+pm_power_off which is called to turn the power off.

+Required Properties:
+- compatibile: Should be "qnap,power-off"

It would do well to have the model number embedded into this compatible
string since it is unlikely that every single QNAP device will use the
same controller interface.

Hi Grant

All QNAP devices known to mainline use this same controller interface.

So that would be ts109, ts209, ts409, ts119, ts219, ts419, plus a few
other models which we don't differentiate, like ts219P and ts219P+.

Any suggestions what to use in the compatible string?

    Thanks
