Subject: [PATCH 0/5] Add Type-C DP support for RK3399 EVB IND board

From: Chaoyi Chen <chaoyi.chen@...k-chips.com>

The RK3399 EVB IND board has a Type-C interface DisplayPort. It use
fusb302 chip as Type-C controller.

This series focuses on adding TCPM support for USBDP PHY and DP driver.
Before this, the USBDP PHY and DP controller of RK3399 sensed state
changes through extcon, and devices such as the RK3399 Gru-Chromebook
rely on them. This series should not break them.

Patch1 add missing "displayport" prop for USB connector binding.
Patch2 add new Type-C mode/orientation switch for RK3399 USBDP phy
binding.
Patch3 add TCPM support for RK3399 USBDP PHY.
Patch4 add TCPM support for CDN-DP.
Patch5 add Type-C DP support for RK3399 EVB IND board.
