Subject: [PATCH v6 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/[email protected]/

[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@7d000: '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]:
https://lore.kernel.org/linux-arm-msm/[email protected]/T/

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 <[email protected]>
---
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

/local/mnt/workspace/varada/varda-linux/arch/arm64/boot/dts/qcom/ipq9574-al02-c7.dtb: phy@7d000: '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@8a00000: 'power-domains' is a required property
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)

Changes in v5:
- Move "host" mode specification to board dts
- Due to dependency with earlier patches board dts
filename changed ipq9574-al02-c7.dts -> ipq9574-rdp433.dts

Changes in v2:
- Fix node placement and coding style
- "ok" -> "okay"

Looks like you just ignored my comment that you need to rename this
clock (and update the binding). :(

Sorry. My mistake. Will post a new patch.
Ignore V7. Missed the update in the binding.
