···
 - compatible: Must be:
   - Tegra124: "nvidia,tegra124-xusb-padctl"
   - Tegra132: "nvidia,tegra132-xusb-padctl", "nvidia,tegra124-xusb-padctl"
+  - Tegra210: "nvidia,tegra210-xusb-padctl"
 - reg: Physical base address and length of the controller's registers.
 - resets: Must contain an entry for each entry in reset-names.
 - reset-names: Must include the following entries:
···
 
 For Tegra124 and Tegra132, the following pads exist: usb2, ulpi, hsic, pcie
 and sata. No extra resources are required for operation of these pads.
+
+For Tegra210, the following pads exist: usb2, hsic, pcie and sata. Below is
+a description of the properties of each pad.
+
+UTMI pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+  - "trk": phandle and specifier referring to the USB2 tracking clock
+
+HSIC pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+  - "trk": phandle and specifier referring to the HSIC tracking clock
+
+PCIe pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+  - "pll": phandle and specifier referring to the PLLE
+- resets: Must contain an entry for each entry in reset-names.
+- reset-names: Must contain the following entries:
+  - "phy": reset for the PCIe UPHY block
+
+SATA pad:
+---------
+
+Required properties:
+- resets: Must contain an entry for each entry in reset-names.
+- reset-names: Must contain the following entries:
+  - "phy": reset for the SATA UPHY block
 
 
 PHY nodes:
···
   - functions: "snps", "xusb"
 - pcie: pcie-0, pcie-1, pcie-2, pcie-3, pcie-4
   - functions: "pcie", "usb3-ss"
+- sata: sata-0
+  - functions: "usb3-ss", "sata"
+
+For Tegra210, the list of valid PHY nodes is given below:
+- utmi: utmi-0, utmi-1, utmi-2, utmi-3
+  - functions: "snps", "xusb", "uart"
+- hsic: hsic-0, hsic-1
+  - functions: "snps", "xusb"
+- pcie: pcie-0, pcie-1, pcie-2, pcie-3, pcie-4, pcie-5, pcie-6
+  - functions: "pcie-x1", "usb3-ss", "pcie-x4"
 - sata: sata-0
   - functions: "usb3-ss", "sata"
 
···
   to map this super-speed USB port to. The range of valid port numbers varies
   with the SoC generation:
   - 0-2: for Tegra124 and Tegra132
+  - 0-3: for Tegra210
 
 Optional properties:
 - nvidia,internal: A boolean property whose presence determines that a port
···
 - 1x ULPI: ulpi-0
 - 2x HSIC: hsic-0, hsic-1
 - 2x super-speed USB: usb3-0, usb3-1
+
+For Tegra210, the XUSB pad controller exposes the following ports:
+- 4x USB2: usb2-0, usb2-1, usb2-2, usb2-3
+- 2x HSIC: hsic-0, hsic-1
+- 4x super-speed USB: usb3-0, usb3-1, usb3-2, usb3-3
