power: qpnp-typec: Add snapshot of qpnp-typec driver 



This is snapshot of the qpnp-typec driver as of msm-3.18
commit a1898eec073a ("power: qpnp-typec: add support for QPNP Type-C
module").
While at it, fix minor structure declaration error.

QPNP USB Type-C module



QPNP USB Type-C module supports USB type-c ports and detection of

USB Type-C chargers that can supply upto 3A Vbus current for charging.



The QPNP USB Type-C interfaces via the SPMI bus.



Required properties :

- compatible : Must be "qcom,qpnp-typec"

- reg:			The SPMI address for this peripheral

- 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.



			- vrd-change:		Triggers on change in current

						capability of charger.

			- ufp-detach:		Triggers on cable detach in

						UFP mode.

			- ufp-detect:		Triggers on charger insertion.

			- dfp-detach:		Triggers on cable detach in

						DFP mode.

			- dfp-detect:		Triggers on OTG cable insertion.

			- vbus-err:		Triggers if VBUS is not

						detected within 275 msec after

						CC detection in UFP mode.

			- vconn-oc:		Triggers on VCONN overcurrent

						in DFP mode with active cable.



Optional properties:

- pinctrl-names : This should be defined if a target uses pinctrl framework

  for SSMUX control pin. See "pinctrl" in

  Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.

  It should specify the names of the configs that pinctrl can install in driver.

  Following are the pinctrl config that can be installed:

      "typec_ssmux_config" : Default configuration of pins.

- <supply-name>-supply: handle to the regulator device tree node.

        "supply-name" is "ss-mux" regulator to drive super-speed MUX chip.

- qcom,role-reversal-supported : A boolean property that when present enables

			support of dual role class.



Example:

	qcom,qpnp-typec@bf00 {

		compatible = "qcom,qpnp-typec";

		reg = <0xbf00 0x100>;

		interrupts =	<0x0 0xbf 0x0>,

				<0x0 0xbf 0x1>,

				<0x0 0xbf 0x2>,

				<0x0 0xbf 0x3>,

				<0x0 0xbf 0x4>,

				<0x0 0xbf 0x6>,

				<0x0 0xbf 0x7>;



		interrupt-names =	"vrd-change",

					"ufp-detach",

					"ufp-detect",

					"dfp-detach",

					"dfp-detect",

					"vbus-err",

					"vconn-oc";

	};

	  The QPNP Type-C module supports the USB type-C protocol. It supports

	  type-C cable detection and other type-C parameters such as

	  current-capability and CC-orientation. The module does not support

	  USB power-delivery. The driver adds support to report these type-C
