| 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_p1": 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 |
| |
