[v4,0/6] Introduce PMIC based USB type C detection

Message

Wesley Cheng June 26, 2020, 6:55 p.m. UTC

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.

[1/2] regulator: Add support for QCOM PMIC VBUS booster
      commit: 4fe66d5a62fbe1b050e783e7a01f986632c08c44
[2/2] regulator: Add dt-binding for QCOM PMIC VBUS output regulator
      commit: a824bab7c62d7ecd8ccfe9693da7ccb7e4683760

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
