The controllers route orientation and DisplayPort mode changes through the USB/DP combo PHY lane switches, but that PHY support is not upstream yet, so the connector graph endpoints are left out for now. The Type-C ports are still registered and reported, only the lane switching is deferred until the PHY nodes are available. Both controllers report through the same level-triggered interrupt line, which the driver handles with a shared interrupt. The I2C bus runs at 100 kHz because the RTS5453H I2C interface does not support higher rates.
