The Cadence D-PHY can be configured in Tx (DSI) mode or Rx (CSI) mode. Both modes have a different programming sequence and share little among them. In addition, a PHY configured in Tx mode cannot be used in Rx mode and vice versa. For this reason, create a separate driver for the Rx mode to make it easier to read and maintain.
