-NVIDIA Tegra194 P2U binding
-
-Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
-Speed) each interfacing with 12 and 8 P2U instances respectively.
-A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
-interface and PHY of HSIO/NVHS bricks. Each P2U instance represents one PCIe
-lane.
-
-Required properties:
-- compatible: For Tegra19x, must contain "nvidia,tegra194-p2u".
-- reg: Should be the physical address space and length of respective each P2U
-       instance.
-- reg-names: Must include the entry "ctl".
-
-Required properties for PHY port node:
-- #phy-cells: Defined by generic PHY bindings.  Must be 0.
-
-Refer to phy/phy-bindings.txt for the generic PHY binding properties.
-
-Example:
-
-p2u_hsio_0: phy@...0000 {
-	compatible = "nvidia,tegra194-p2u";
-	reg = <0x03e10000 0x10000>;
-	reg-names = "ctl";
-
-	#phy-cells = <0>;
-};
