Subject: [PATCH v7 0/8] Enable IPQ9754 USB

This patch series adds the relevant phy and controller
configurations for enabling USB on IPQ9754

Depends on:
https://lore.kernel.org/all/20230217142030.16012-1-quic_devipriy@quicinc.com/

[v7]:
	- com_aux -> cfg_ahb in patch 7

[v6]:
        - Incorporated review comments
	- Resolve make dtbs_check messages
	- Fixed pcs_usb offset
	- Board dts file name changed

[v5]:
        - Incorporated review comments
	- 'make dtbs_check' giving the following messages since
	  ipq9574 doesn't have power domains. Hope this is ok

		/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: phy@...00: 'power-domains' is a required property
        	From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/phy/qcom,sc8280xp-qmp-usb3-uni-phy.yaml

        	From schema: /local/mnt/workspace/varada/varda-linux/Documentation/devicetree/bindings/usb/qcom,dwc3.yaml

	- Move qmp phy DT node to newer specification

[v4]:
        - Incorporated review comments
	- Address all 'make dtbs_check' errors

[v3]:
        - Incorporated review comments regarding coding style

[v2]:
        - Incorporated review comments regarding coding style,
          maintaining sorted order of entries and unused phy register
          offsets
