+MT8173 xHCI
+
+The device node for Mediatek SOC USB3.0 host controller
+
+Required properties:
+ - compatible : should contain "mediatek,mt8173-xhci"
+ - reg : specifies physical base address and size of the registers,
+ the first one for MAC, the second for IPPC
+ - interrupts : interrupt used by the controller
+ - power-domains : a phandle to USB power domain node to control USB's
+ mtcmos
What's that?
+ - vusb33-supply : regulator of USB avdd3.3v
+
+ - clocks : a list of phandle + clock-specifier pairs, one for each
+ entry in clock-names
+ - clock-names : must contain
+ "sys_ck": for clock of xHCI MAC
+ "wakeup_deb_p0": for USB wakeup debounce clock of port0
+ "wakeup_deb_p0": for USB wakeup debounce clock of port1
"wakeup_deb_p1"?
+
+ - phys : a list of phandle + phy specifier pairs
+
+Optional properties:
+ - mediatek,wakeup-src : 1: ip sleep wakeup mode; 2: line state wakeup
^^ IP?
+ mode;
+ - mediatek,syscon-wakeup : phandle to syscon used to access USB wakeup
+ control register, it depends on "mediatek,wakeup-src".
+ - vbus-supply : reference to the VBUS regulator;
+ - usb3-lpm-capable : supports USB3.0 LPM
