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 6.16.

Changes in v4:
- replaced sprintf with sysfs_emit
- changed priority to u8
- added an overflow check to typec_mode_set_priority(), now returning
-EOVERFLOW on failure

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