[PATCH v3] arm64: dts: qcom: shikra: Add CYPD6129/CYPD6229 Type-C controller support
From: Akash Kumar
Date: Mon Oct 12 2026 - 05:49:05 EST
This series adds support for the Cypress cypd6129/cypd6229 dual
Type-C PD controllers used on the Shikra CQM/CQS/IQS platforms to
handle usb-role-switch, and wires up the corresponding DT nodes.

Patch v3 adds the Shikra board-specific Device Tree changes required to
connect the CYPD6129/CYPD6229 Type-C PD controllers to the USB controllers.
On the CQM and CQS platforms, enable the CYPD6129 controller on I2C3,
configure its GPIO136 interrupt, and connect its Type-C connector to USB2.
Both USB controllers are configured in OTG mode to allow role switching.
On the IQS platform, enable the CYPD6229 controller with the CYPD6129
fallback compatible, configure its GPIO50 interrupt, and describe both
Type-C connectors. The first connector is connected to USB2, while the
second connector is connected to USB1, including its SuperSpeed path.
The changes also add the required pinctrl configuration, wakeup-source
property, I2C alias, VBUS boost GPIO hog, and USB endpoint
remote-endpoint connections.
