Subject: [PATCH v6 7/8] arm64: dts: qcom: ipq9574: Add USB related nodes
Add USB phy and controller related nodes
Signed-off-by: Varadarajan Narayanan <quic_varada@...cinc.com>
---
Changes in v6:
- Introduce fixed regulators for the phy
- Resolved all 'make dtbs_check' messages
Changes in v5:
- Fix additional comments
- Edit nodes to match with qcom,sc8280xp-qmp-usb3-uni-phy.yaml
- 'make dtbs_check' giving the following messages since
ipq9574 doesn't have power domains. Hope this is ok

From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/usb/qcom,dwc3.yaml
Changes in v4:
- Use newer bindings without subnodes
- Fix coding style issues
Changes in v3:
- Insert the nodes at proper location
Changes in v2:
- Fixed issues flagged by Krzysztof
- Fix issues reported by make dtbs_check
- Remove NOC related clocks (to be added with proper
interconnect support)
