MediaTek xHCI
|
|
|
|
The device node for USB3 host controller on MediaTek SoCs.
|
|
|
|
Required properties:
|
|
- compatible : should be "mediatek,mtk-xhci"
|
|
- reg : specifies physical base address and size of the registers
|
|
- reg-names: should be "mac" for xHCI MAC and "ippc" for IP port control
|
|
- 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": controller clock used by normal mode,
|
|
the following ones are optional:
|
|
"ref_ck": reference clock used by low power mode etc,
|
|
"mcu_ck": mcu_bus clock for register access,
|
|
"dma_ck": dma_bus clock for data transfer by DMA,
|
|
"xhci_ck": controller clock
|
|
|
|
- phys : list of all the USB PHYs on this HCD
|
|
- phy-names: name specifier for the USB PHY
|
|
|
|
Optional properties:
|
|
- vbus-supply : reference to the VBUS regulator;
|
|
- mediatek,u3p-dis-msk : mask to disable u3ports, bit0 for u3port0,
|
|
bit1 for u3port1, ... etc;
|
|
- mediatek,u2p-dis-msk : mask to disable u2ports, bit0 for u2port0,
|
|
bit1 for u2port1, ... etc;
|
|
|
|
Example:
|
|
xhci: usb@1a0c0000 {
|
|
compatible = "mediatek,mt7629-xhci", "mediatek,mtk-xhci";
|

reg = <0x1a0c0000 0x1000>, <0x1a0c3e00 0x0100>;
|
|
reg-names = "mac", "ippc";
|

|
|
clocks = <&ssusbsys CLK_SSUSB_SYS_EN>, <&ssusbsys CLK_SSUSB_REF_EN>,
|
|
<&ssusbsys CLK_SSUSB_MCU_EN>, <&ssusbsys CLK_SSUSB_DMA_EN>;
|
|
clock-names = "sys_ck", "ref_ck", "mcu_ck", "dma_ck";
|
|
phys = <&u2port0 PHY_TYPE_USB2>, <&u3port0 PHY_TYPE_USB3>;
|
|
status = "disabled";
|
|
};
