[PATCH 0/3] Add usb-role-switch support for USB Type-C ports on Shikra

[Akash Kumar]

The USB DT support series for Shikra ("Add DT Support for USB on
Shikra") enabled both USB controllers in device mode, since role
switching support was not yet present:

https://lore.kernel.org/all/20260811-usb-shikra-v7-v7-2-753e928f37ae@oss.qualcomm.com/

This series adds that role-switching support. On Shikra CQS/CQM
platforms, usb-role-switch is handled by PM4125 on the primary
Type-C port and Cypress PD controller CYPD6129 on the second Type-C
port. On Shikra IQS platform, usb-role-switch is handled by Cypress
PD controller CYPD6129 on both Type-C ports.

Patch 1 adds the device-tree binding for the CYPD6129/CYPD6229 dual
Type-C PD controllers. Patch 2 adds the corresponding compatible
strings to the ucsi_ccg driver's of_device_id table so it binds to
boards describing these controllers. Patch 3 wires up the CYPD6129
typec node on the affected Shikra boards and switches usb_1/usb_2 to
OTG mode so role switching can take effect.

[PATCH 1/3] dt-bindings: usb: Add Cypress cypd6129/cypd6229 Type-C controller

[Akash Kumar]

Add the device-tree binding documentation for the Cypress cypd6129
and cypd6229 dual Type-C PD controllers. These are used on Shikra
CQM/CQS/IQS platforms to handle usb-role-switch for the USB Type-C
ports over an I2C interface, similarly to the existing cypd4226
binding.

cypd6229 is a variant of cypd6129 and is described with a
"cypress,cypd6129" fallback compatible string.

[PATCH 2/3] usb: typec: ucsi: ccg: Add support for cypd6129/cypd6229

[Akash Kumar]

Add cypd6129 and cypd6229 compatible strings to the of_device_id
match table so the driver binds to boards describing these Cypress
PD controllers in their device tree. No other driver changes are
needed since the chip is accessed through the same generic UCSI/HPI
I2C register protocol as the existing cypd4226 support.

[PATCH 3/3] arm64: dts: qcom: shikra: Wire up usb-role-switch for USB Type-C ports

[Akash Kumar]

On Shikra CQS/CQM platforms, usb-role-switch is handled by PM4125 on
the primary Type-C port and Cypress PD controller CYPD6129 on the
second Type-C port. On Shikra IQS platform, usb-role-switch is
handled by Cypress PD controller CYPD6129 on both Type-C ports.

Add the CYPD6129 typec node under i2c3, wire its connector endpoints
to the corresponding DWC3 controller ports via remote-endpoint
phandles, and switch the associated USB controllers to OTG mode so
role switching can take effect.

AFAICT, this fails dtbs_check because it isn't allowed by the
usb-connector.yaml.

I see you added it in the example the new schema you added. That
should've failed at dt_bindings_check.

Same comment for the other dtes files.

I don't think this property is actually defined anywhere. I wonder which
tree is this done on.

[PATCH v2 0/3] arm64: dts: qcom: shikra: Add CYPD6129/CYPD6229 Type-C controller support

[Akash Kumar]

This series adds support for the Cypress cypd6129/cypd6229 dual
Type-C PD controllers used on the Shikra CQM/CQS/IQS platforms to
handle usb-role-switch, and wires up the corresponding DT nodes.

Changes in v2:
- dt-bindings: add a top-level "wakeup-source" property on the
  controller node (matching richtek,rt1719.yaml/ti,tps6598x.yaml) and
  move "wakeup-source;" in the example out of "connector@0" onto the
  parent node, since usb-connector.yaml ends in
  "unevaluatedProperties: false" and does not itself declare
  "wakeup-source" -- placing it inside the connector node fails
  dtbs_check. Also fixed related whitespace nitpicks in the example.
- dts: apply the same wakeup-source relocation to all three affected
  boards (shikra-cqm-evk, shikra-cqs-evk, shikra-iqs-evk).
- dts: fix shikra-iqs-evk's cypd6229 node to use the
  "cypress,cypd6229", "cypress,cypd6129" fallback compatible string
  pair required by the binding, instead of "cypress,cypd6229" alone.
- dts: fix shikra-cqm-evk/shikra-cqs-evk wiring so CYPD6129 connects
  to usb_2_dwc3_hs (secondary port) and PM4125's built-in typec
  connects to usb_1_dwc3_hs/pm4125_hs_in (primary port), and add the
  missing reverse remote-endpoint links on pm4125_hs_in/pm4125_ss_in.
- No changes to patch 2/3 (driver match table).

[PATCH v2 1/3] dt-bindings: usb: Add Cypress cypd6129/cypd6229 Type-C controller

[Akash Kumar]

Add the device-tree binding documentation for the Cypress cypd6129
and cypd6229 dual Type-C PD controllers. These are used on Shikra
CQM/CQS/IQS platforms to handle usb-role-switch for the USB Type-C
ports over an I2C interface, similarly to the existing cypd4226
binding.

cypd6229 is a variant of cypd6129 and is described with a
"cypress,cypd6129" fallback compatible string.

[PATCH v2 2/3] usb: typec: ucsi: ccg: Add support for cypd6129/cypd6229

[Akash Kumar]

Add cypd6129 and cypd6229 compatible strings to the of_device_id
match table so the driver binds to boards describing these Cypress
PD controllers in their device tree. No other driver changes are
needed since the chip is accessed through the same generic UCSI/HPI
I2C register protocol as the existing cypd4226 support.

[PATCH v2 3/3] arm64: dts: qcom: shikra: Wire up usb-role-switch for USB Type-C ports

[Akash Kumar]

On Shikra CQS/CQM platforms, usb-role-switch is handled by PM4125 on
the primary Type-C port and Cypress PD controller CYPD6129 on the
second Type-C port. On Shikra IQS platform, usb-role-switch is
handled by Cypress PD controller CYPD6129 on both Type-C ports.

Add the CYPD6129 typec node under i2c3, wire its connector endpoints
to the corresponding DWC3 controller ports via remote-endpoint
phandles, and switch the associated USB controllers to OTG mode so
role switching can take effect.
