+MediaTek XS-PHY binding
+--------------------------
+
+The XS-PHY controller supports physical layer functionality for USB3.1
+GEN2 controller on MediaTek SoCs.
+
+Required properties (controller (parent) node):
+ - compatible : should be "mediatek,<soc-model>-xsphy", "mediatek,xsphy",
+ soc-model is the name of SoC, such as mt3611 etc;
+ when using "mediatek,xsphy" compatible string, you need SoC specific
+ ones in addition, one of:
+ - "mediatek,mt3611-xsphy"
+
+ - #address-cells, #size-cells : should use the same values as the root node
+ - ranges: must be present
+
+Optional properties (controller (parent) node):
+ - reg : offset and length of register shared by multiple U3 ports,
+ exclude port's private register, if only U2 ports provided,
+ shouldn't use the property.
+ - mediatek,src-ref-clk-mhz : u32, frequency of reference clock for slew rate
+ calibrate
+ - mediatek,src-coef : u32, coefficient for slew rate calibrate, depends on
+ SoC process
+
+Required nodes : a sub-node is required for each port the controller
+ provides. Address range information including the usual
+ 'reg' property is used inside these nodes to describe
+ the controller's topology.
+
+Required properties (port (child) node):
+- reg : address and length of the register set for the port.
+- clocks : a list of phandle + clock-specifier pairs, one for each
+ entry in clock-names
+- clock-names : must contain
+ "ref": 48M reference clock for HighSpeed analog phy; and 26M
+ reference clock for SuperSpeedPlus analog phy, sometimes is
+ 24M, 25M or 27M, depended on platform.
+- #phy-cells : should be 1
+ cell after port phandle is phy type from:
+ - PHY_TYPE_USB2
+ - PHY_TYPE_USB3
+
+The following optional properties are only for debug or HQA test
+Optional properties (PHY_TYPE_USB2 port (child) node):
+- mediatek,eye-src : u32, the value of slew rate calibrate
+- mediatek,eye-vrt : u32, the selection of VRT reference voltage
+- mediatek,eye-term : u32, the selection of HS_TX TERM reference voltage
+- mediatek,efuse-intr : u32, the selection of Internal Resistor
+
+Optional properties (PHY_TYPE_USB3 port (child) node):
+- mediatek,efuse-intr : u32, the selection of Internal Resistor
+- mediatek,efuse-tx-imp : u32, the selection of TX Impedance
+- mediatek,efuse-rx-imp : u32, the selection of RX Impedance
