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 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 PHY driver has register a notification, to get the alt mode from PD,
the PD driver need call the tcphy_notifier_call_chain to notify PHY and
DP controller.
For the notification for the port status change from PD, I think we can
use the extcon class, pls reference the code in drivers/extcon/ for usage.
Thanks,

This series is based on Mark Yao's branch:
https://github.com/markyzq/kernel-drm-rockchip/tree/drm-rockchip-next-2016-05-23
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.
