Changes in v9:
 - Fixed dt-binding to reference usb-connector from the 'connector' node,
   removed properties that didn't have further constraints (than specified in
   usb-connector.yaml), and make 'reg' a required property.
 - Moved vbus_reg get call into probe(), and will fail if the regulator is not
   available.
 - Removed some references from qcom_pmic_typec, as they were not needed after
   probe().
 - Moved interrupt registration until after all used variables were initialized.

Changes in v8:
 - Simplified some property definitions, and corrected the
   connector reference in the dt binding.

Changes in v7:
 - Fixups in qcom-pmic-typec.c to remove uncesscary includes, printk formatting,
   and revising some logic operations. 

Changes in v6:
 - Removed qcom_usb_vbus-regulator.c and qcom,usb-vbus-regulator.yaml from the
   series as they have been merged on regulator.git
 - Added separate references to the usb-connector.yaml in qcom,pmic-typec.yaml
   instead of referencing the entire schema.

Changes in v5:
 - Fix dt_binding_check warning/error in qcom,pmic-typec.yaml

Changes in v4:
 - Modified qcom,pmic-typec binding to include the SS mux and the DRD remote
   endpoint nodes underneath port@1, which is assigned to the SSUSB path
   according to usb-connector
 - Added usb-connector reference to the typec dt-binding
 - Added tags to the usb type c and vbus nodes
 - Removed "qcom" tags from type c and vbus nodes
 - Modified Kconfig module name, and removed module alias from the typec driver
 
Changes in v3:
 - Fix driver reference to match driver name in Kconfig for
   qcom_usb_vbus-regulator.c
 - Utilize regulator bitmap helpers for enable, disable and is enabled calls in
   qcom_usb_vbus-regulator.c
 - Use of_get_regulator_init_data() to initialize regulator init data, and to
   set constraints in qcom_usb_vbus-regulator.c
 - Remove the need for a local device structure in the vbus regulator driver
 
Changes in v2:
 - Use devm_kzalloc() in qcom_pmic_typec_probe()
 - Add checks to make sure return value of typec_find_port_power_role() is
   valid
 - Added a VBUS output regulator driver, which will be used by the PMIC USB
   type c driver to enable/disable the source
 - Added logic to control vbus source from the PMIC type c driver when
   UFP/DFP is detected
 - Added dt-binding for this new regulator driver
 - Fixed Kconfig typec notation to match others
 - Leave type C block disabled until enabled by a platform DTS
