| |
| DWC3- USB3 CONTROLLER |
| |
| Required properties: |
| - compatible: must be "synopsys,dwc3" |
| - reg : Address and length of the register set for the device |
| - interrupts: Interrupts used by the dwc3 controller. |
| - usb-phy : array of phandle for the PHY device |
| |
| Optional properties: |
| - tx-fifo-resize: determines if the FIFO *has* to be reallocated. |
| - snps,host-only-mode: if present then dwc3 should be run in HOST only mode. |
| - snps,nominal-elastic-buffer: When set, the nominal elastic buffer setting |
| is used. By default, the half-full setting is used. |
| - snps,ssphy-clear-auto-suspend-on-disconnect: If present, clear auto suspend feaure with ssusb phy |
| during cable disconnect. |
| - snps,usb3-u1u2-disable: If present, disable u1u2 low power modes for DWC3 core controller in SS mode. |
| - snps,hird_thresh: If present, will determine the value of DCTL[HIRD_Thresh] which, in turn, |
| controls the UTMI sleep mechanism vs. the PHY. Default value is 12. |
| - snps,bus-suspend-enable: If present then controller supports low power mode |
| during bus suspend. |
| - snps,lpm-nyet-thresh: If present, will determine the value of DCTL[LPM_NYET_Thres]. |
| If BESL value received from the host in the LPM token is less than this value we send LPM ACK to the host. |
| Otherwise the device returns LPM NYET. |
| |
| This is usually a subnode to DWC3 glue to which it is connected. |
