Merge "usb: pd: add snapshot of qpnp-pdphy and policy_engine drivers"

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.

- qcom,default-sink-caps: List of 32-bit values representing the nominal sink

			capabilities in voltage (millivolts) and current

			(milliamps) pairs.

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>;

		interrupt-names = "sig-tx",

				  "sig-rx",

				  "msg-tx",

				  "msg-rx",

				  "msg-tx-failed",

				  "msg-tx-discarded",

				  "msg-rx-discarded";

		qcom,default-sink-caps = <5000 3000>, /* 5V @ 3A */

					 <9000 3000>, /* 9V @ 3A */

					 <12000 2250>; /* 12V @ 2.25A */
