[PATCH v5 0/4] USB Type-C alternate mode priorities

[Andrei Kuchynski]

This patch series introduces a mechanism for setting USB Type-C alternate
mode priorities. It allows the user to specify their preferred order for
mode selection, such as USB4, Thunderbolt, or DisplayPort.

A new sysfs attribute named 'priority' is exposed to provide user-space
control over the mode selection process.

This series was tested on a Android OS device running kernel 6.18.0-rc6.

Changes in v5:
- Patches 3 and 4 (v4) have been consolidated into a singular patch,
keeping the mode priority implementation within drivers/usb/typec/class.c.

Andrei Kuchynski (4):
  usb: typec: Add mode_control field to port property
  platform/chrome: cros_ec_typec: Set no_mode_control flag
  usb: typec: ucsi: Set no_mode_control flag
  usb: typec: Expose alternate mode priority via sysfs
