<wcheng@codeaurora.org>: 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 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.

2020-07-01regulator: lp87565: enable voltage regardless of ENx pinLuca Ceresoli1-2/+19
This driver enables outputs by setting bit EN_BUCKn in the BUCKn_CTRL1 register. However, if bit EN_PIN_CTRLn in the same register is set, the output is actually enabled only if EN_BUCKn is set AND an enable pin is active. Since the driver does not touch EN_PIN_CTRLn, the choice is left to the hardware, which in turn gets this bit from OTP memory, and in absence of OTP data it uses a default value that is documented in the datasheet for LP8752x, but not for LP8756x. Thus the driver doesn't really "know" whether it is actually enabling the output or not. In order to make sure activation is always driver-controlled, just clear the EN_PIN_CTRLn bit. Now all activation solely depend on the EN_BUCKn bit.
