[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:

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.
