Qualcomm Technologies, Inc. QPNP PD PHY - USB Power Delivery Physical layer

Required properties:
- compatible:		Must be "qcom,qpnp-pdphy"
- reg:			The base address for this peripheral
- vdd-pdphy-supply:	phandle to the VDD supply regulator node
- interrupts:		Specifies the interrupt associated with the peripheral.
- interrupt-names:	Specifies the interrupt names for the peripheral. Every
			available interrupt needs to have an associated name
			with it to indentify its purpose.

			The following interrupts are required:

			0: sig-tx
				Triggers when a signal (HardReset or CableReset)
				has been sent.
			1: sig-rx
				Triggers when a signal has been received.
			2: msg-tx
				Triggers when a message has been sent and the
				related GoodCRC has been received.
			3: msg-rx
				Triggers when a message has been received and
				the related GoodCRC was sent successfully.
			4: msg-tx-failed
				Triggers when a message failed all its
				transmission attempts, either due to a non-idle
				bus or missing GoodCRC reply.
			5: msg-tx-discarded
				Triggers when a message is received while a
				transmission request was in place. The request
				itself is discarded.
			6: msg-rx-discarded
				Triggers when a message was received but had to
				be discarded due to the RX buffer still in use
				by SW.

Optional properties:
- vbus-supply:		Regulator that enables VBUS source output
- vconn-supply:		Regulator that enables VCONN source output. This will
			be supplied on the USB CC line that is not used for
			communication when Ra resistance is detected.
- qcom,vconn-uses-external-source: Indicates whether VCONN supply is sourced
			from an external regulator. If omitted, then it is
			assumed it is connected to VBUS.

Example:
	qcom,qpnp-pdphy@1700 {
		compatible = "qcom,qpnp-pdphy";
		reg = <0x1700 0x100>;
		vdd-pdphy-supply = <&pm8998_l24>;
		interrupts = <0x2 0x17 0x0 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x1 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x2 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x3 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x4 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x5 IRQ_TYPE_EDGE_RISING>,
			     <0x2 0x17 0x6 IRQ_TYPE_EDGE_RISING>;
