                control gpios

 - threshold:   allows setting the "click"-threshold in the range

                from 20 to 80.

                from 0 to 80.

 - gain:        allows setting the sensitivity in the range from 0 to

                31. Note that lower values indicate higher

- reg:                  Base address of PMIC on Hi6220 SoC.

- interrupt-controller: Hi655x has internal IRQs (has own IRQ domain).

- pmic-gpios:           The GPIO used by PMIC IRQ.

- #clock-cells:		From common clock binding; shall be set to 0

Optional properties:

- clock-output-names: From common clock binding to override the

  default output clock name

Example:

	pmic: pmic@f8000000 {

		interrupt-controller;

		#interrupt-cells = <2>;

		pmic-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>;

		#clock-cells = <0>;

	}

  "ext_clock" (External clock provided to the card).

- post-power-on-delay-ms : Delay in ms after powering the card and

	de-asserting the reset-gpios (if any)

- power-off-delay-us : Delay in us after asserting the reset-gpios (if any)

	during power off of the card.

Example:

- phy-reset-active-high : If present then the reset sequence using the GPIO

  specified in the "phy-reset-gpios" property is reversed (H=reset state,

  L=operation state).

- phy-reset-post-delay : Post reset delay in milliseconds. If present then

  a delay of phy-reset-post-delay milliseconds will be observed after the

  phy-reset-gpios has been toggled. Can be omitted thus no delay is

  observed. Delay is in range of 1ms to 1000ms. Other delays are invalid.

- phy-supply : regulator that powers the Ethernet PHY.

- phy-handle : phandle to the PHY device connected to this device.

- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
