Subject: [PATCH v2 0/6] Introduce PMIC based USB type C detection
Date: Fri, 12 Jun 2020 16:19:12 -0700 [thread overview]
Message-ID: <20200612231918.8001-1-wcheng@codeaurora.org> (raw)
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.
