Subject: [PATCH v3 3/4] arm64: dts: qcom: x1e80100-crd: Add Parade PS8830
related nodes
Add nodes for all 3 Parade PS8830 Type-C retimers found on Qualcomm
X Elite CRD board, along with all of their voltage regulators. These
retimers sit between the Type-C connectors and the PHYs, so describe the
pmic glink graph accordingly. On this board, these retimers might be left
enabled and configured by the bootloader, so make sure the retimers don't
reset their configuration on driver probe.
