[RESEND PATCH 1/6] phy: Add USB Type-C PHY driver for rk3399

Chris Zhong
2016-05-27T10:45:37Z

Add a PHY provider driver for the rk3399 SoC Type-c PHY. 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.
