Subject: [PATCH v15 0/5] Enable IPQ9754 USB

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

Portions of the patchset have been merged. Please see
	https://lore.kernel.org/lkml/ZGN9gchu7dRb6QwC@matsya/

[v15]:
	- Introduce fixed regulator definitions in the last patch
	  instead of earlier patch

[v14]:
	- Missed Konrad's comment. Switch order of regulator-boot-on &
          regulator-always-on in mp5496_l2 node

[v13]:
	- Move fixed regulator definitions from SoC dtsi to board dts
	- Remove 'dr_mode' from SoC dtsi
	- Move 'status' property to the end

[v12]:
	- In dtsi usb@...0000 -> usb@...8800

[v11]:
	- Rename dwc_0 -> usb_0_dwc3
	- Minor change in qcom,sc8280xp-qmp-usb3-uni-phy.yaml to factor in
	  latest updates to the file

[v10]:
	- Fix regulator definitions
	- Address couple of other comments

[v9]:
	- Update bindings to make power-domains as optional since
	  IPQ9574 doesn't have GDSCs

[v8]:
	- Update bindings for the clock name change
[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
		/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: usb@...0000: 'power-domains' is a required property
        	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
        - Removed NOC clock entries from DT node (will be implemented
          later with interconnect support)
        - Fixed 'make dtbs_check' errors/warnings

[v1]:
