Hi all This series patch is for rockchip Type-C phy and DisplayPort controller driver. The USB Type-C PHY is designed to support the USB3 and DP applications. The PHY basically has two main components: USB3 and DisplyPort. USB3 operates in SuperSpeed mode and the DP can operate at RBR, HBR and HBR2 data rates. The Type-C cable orientation detection and Power Delivery (PD) is accomplished using a PD PHY or a exernal PD chip. The DP controller is compliant with DisplayPort Specification, Version 1.3, This IP is compatible with the rockchip type-c PHY IP. There is a uCPU in DP controller, it need a firmware to work, please put the firmware file[0] to /lib/firmware/cdn/dptx.bin. The uCPU in charge of aux communication and link training, the host use mailbox to communicate with the ucpu. The DP contoller has register a notification with extcon API, to get the alt mode from PD, the PD driver need call the devm_extcon_dev_allocate to create a extcon device and use extcon_set_state to notify DP controller. And call extcon_set_cable_property to set orientation. About the DP audio, cdn-dp registered 2 DAIs: 0 is I2S, 1 is SPDIF. We can reference them in simple-card. This series is based on Mark Yao's branch[1] and Chanwoo Choi's extcon-test branch[2] I test this patches on the rk3399-evb board, with a fusb302 driver, this branch has no rk3399.dtsi, so the patch about dts is not included in this series.
