-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
