1 | MT8173 xHCI |
| 2 | ||
| 3 | The device node for Mediatek SOC USB3.0 host controller | |
| 4 | ||
| 5 | Required properties: | |
| 6 | - compatible : should contain "mediatek,mt8173-xhci" | |
| 7 | - reg : specifies physical base address and size of the registers, | |
| 8 | the first one for MAC, the second for IPPC | |
| 9 | - interrupts : interrupt used by the controller | |
| 10 | - power-domains : a phandle to USB power domain node to control USB's | |
| 11 | mtcmos | |
| 12 | - vusb33-supply : regulator of USB avdd3.3v | |
| 13 | ||
| 14 | - clocks : a list of phandle + clock-specifier pairs, one for each | |
| 15 | entry in clock-names | |
| 16 | - clock-names : must contain | |
| 17 | "sys_ck": for clock of xHCI MAC | |
| 18 | "wakeup_deb_p0": for USB wakeup debounce clock of port0 | |
| 19 | "wakeup_deb_p1": for USB wakeup debounce clock of port1 | |
| 20 | ||
| 21 | - phys : a list of phandle + phy specifier pairs | |
| 22 | ||
| 23 | Optional properties: | |
| 24 | - mediatek,wakeup-src : 1: ip sleep wakeup mode; 2: line state wakeup | |
| 25 | mode; | |
| 26 | - mediatek,syscon-wakeup : phandle to syscon used to access USB wakeup | |
| 27 | control register, it depends on "mediatek,wakeup-src". | |
| 28 | - vbus-supply : reference to the VBUS regulator; | |
| 29 | - usb3-lpm-capable : supports USB3.0 LPM | |
| 30 | ||
