+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
|
|
+ - 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
|
|
+
|
|
+ - phys : a list of phandle + phy specifier pairs
|
|
+
|
|
+Optional properties:
|
|
+ - mediatek,wakeup-src : 1: ip sleep wakeup mode; 2: line state wakeup
|
|
+ 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
|
|
+
|
|
+Example:
|
|
+usb30: usb@11270000 {
|
|
+ compatible = "mediatek,mt8173-xhci";
|
|
+ reg = <0 0x11270000 0 0x1000>,
|
|
+ <0 0x11280700 0 0x0100>;
|
|
+ interrupts = <GIC_SPI 115 IRQ_TYPE_LEVEL_LOW>;
|
|
+ power-domains = <&scpsys MT8173_POWER_DOMAIN_USB>;
|
|
+ clocks = <&topckgen CLK_TOP_USB30_SEL>,
|
|
+ <&pericfg CLK_PERI_USB0>,
|
|
+ <&pericfg CLK_PERI_USB1>;
|
|
+ clock-names = "sys_ck",
|
|
+ "wakeup_deb_p0",
|
|
+ "wakeup_deb_p1";
