[PATCH v3 0/4] Samsung Galaxy Express SGH-I437 Support

[PATCH v3 0/4] Samsung Galaxy Express SGH-I437 Support

[Rudraksha Gupta]

This patch series adds support for the Samsung Galaxy Express SGH-I437.
Currently the following things work on this phone: UART, eMMC, SD Card, and
USB.

version 3:
- Added Ack
- Fixed compatible in qcom,usb-hs-phy.yaml. `make dt_binding_check dtbs_check`
  no longer complains about USB
- Fixed formatting in qcom-msm8960.dtsi and qcom-msm8960-samsung-expressatt.dts
- Fixed the spi1_default node in qcom-msm8960-samsung-expressatt.dts.
  `make dt_binding_check dtbs_check` no longer complains

version 2:
- Combined patch 1 into patch 4, as the sleep_clk label is specifically needed
  for the USB node.
- Reformatted the commit messages to align with the style used in other commit
  messages that modify the same files.
- Included a cover letter to provide an overview of the patch series.
- Slight refactoring of the device tree source (DTS) file.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230604063032.365775-3-guptarud@gmail.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

I see. Why is it off the latest rc1 and not off the latest commit?

Thanks. I didn't see these errors as I was only looking for expressatt
binding errors.

I have no clue what you want to achieve here. You break the bindings.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Best regards,
Krzysztof

When I added the USB node to the msm8960 dtsi file, I got similar
messages for the expressatt/cdp that Rob mentioned in his email reply:

phy: resets: [[25, 0]] is too short
phy: reset-names:0: 'phy' was expected
phy: reset-names: ['por'] is too short

I will send an updated patch soon that addresses this.

Sorry. I was only looking for expressatt errors/warnings and failed to
see the other errors/warnings in the sea of text.

[PATCH v3 3/4] ARM: dts: qcom: msm8960: Add USB node

[Rudraksha Gupta]

Add the required nodes to support USB on the MSM8960 SoC. As it's very
similar to the APQ8064 SoC, the nodes are almost identical

Add a label to sleep_clk for the USB node to reference
