      Merge series "Introduce PMIC based USB type C detection" from Wesley Cheng <wcheng@codeaurora.org>: · d5ff5fb9
      Mark Brown authored
      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.

      regulator: lp87565: enable voltage regardless of ENx pin · 81fdcef3
      Luca Ceresoli authored
      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.

      regulator: Add dt-binding for QCOM PMIC VBUS output regulator · a824bab7
      Wesley Cheng authored
      This describes how to enable the Qualcomm PMIC VBUS booster used for
      providing power to connected USB peripherals when the USB role is host
      mode.  The driver itself will register the vbus_usb regulator, so that
      external drivers can utilize the enable/disable regulator APIs.
