Subject: [PATCH v2 5/5] arm64: dts: rockchip: rk3399-evb-ind: Add support for DisplayPort
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.
fusb302 chip ---> USB/DP PHY0 <----> CDN-DP controller
Signed-off-by: Chaoyi Chen <chaoyi.chen@...k-chips.com>
---
Changes in v2:
- Add endpoint to link DP PHY and DP controller.
- Fix devicetree coding style.
