Subject: [PATCH v6 1/4] arm64: dts: qcom: x1e80100-crd: Describe the Parade
PS8830 retimers
The X Elite CRD board comes with 3 Parade PS8830 retimers, one for each
Type-C port. These handle the orientation and altmode switching and are
controlled over I2C. In the connection chain, they sit between the
USB/DisplayPort combo PHY and the Type-C connector.
Describe the retimers and all gpio controlled voltage regulators used by
each retimer. Also, modify the pmic glink graph to include the retimers in
between the SuperSpeed/Sideband in endpoints and the QMP PHY out endpoints.
