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 Add the required drivers for implementing type C orientation and role detection using the Qualcomm PMIC. Currently, PMICs such as the PM8150B have an integrated type C block, which can be utilized for this. This series adds the dt-binding, PMIC type C driver, and DTS nodes. The PMIC type C driver will register itself as a type C port w/ a registered type C switch for orientation, and will fetch a USB role switch handle for the role notifications. It will also have the ability to enable the VBUS output to any connected devices based on if the device is behaving as a UFP or DFP.
