+ *
+ * The ROCKCHIP Type-C PHY has two PLL clocks. The first PLL clock
+ * is used for USB3, the second PLL clock is used for DP. This Type-C PHY has
+ * 3 working modes: USB3 only mode, DP only mode, and USB3+DP mode.
+ * At USB3 only mode, both PLL clocks need to be initialized, this allows the
+ * PHY to switch mode between USB3 and USB3+DP, without disconnecting the USB
+ * device.
+ * In The DP only mode, only the DP PLL needs to be powered on, and the 4 lanes
+ * are all used for DP.
+ *
+ * This driver gets extcon cable state and property, then decides which mode to
+ * select:
+ *
+ * 1. USB3 only mode:
+ *    EXTCON_USB or EXTCON_USB_HOST state is true, and
+ *    EXTCON_PROP_USB_SS property is true.
+ *    EXTCON_DISP_DP state is false.
+ *
+ * 2. DP only mode:
+ *    EXTCON_DISP_DP state is true, and
+ *    EXTCON_PROP_USB_SS property is false.
+ *    If EXTCON_USB_HOST state is true, it is DP + USB2 mode, since the USB2 phy
+ *    is a separate phy, so this case is still DP only mode.
+ *
+ * 3. USB3+DP mode:
+ *    EXTCON_USB_HOST and EXTCON_DISP_DP are both true, and
+ *    EXTCON_PROP_USB_SS property is true.
+ *
+ * This Type-C PHY driver supports normal and flip orientation. The orientation
+ * is reported by the EXTCON_PROP_USB_TYPEC_POLARITY property: true is flip
+ * orientation, false is normal orientation.
