synopsys DWC3 CORE
|
|
|
|
DWC3- USB3 CONTROLLER
|
|
|
|
Required properties:
|
|
- compatible: must be "snps,dwc3"
|
|
- reg : Address and length of the register set for the device
|
|
- interrupts: Interrupts used by the dwc3 controller.
|
|
|
|
Optional properties:
|
|
- usb-phy : array of phandle for the PHY device. The first element
|
|
in the array is expected to be a handle to the USB2/HS PHY and
|
|
the second element is expected to be a handle to the USB3/SS PHY
|
|
- phys: from the *Generic PHY* bindings
|
|
- phy-names: from the *Generic PHY* bindings
|
|
- tx-fifo-resize: determines if the FIFO *has* to be reallocated.
|
|
- snps,disable_scramble_quirk: true when SW should disable data scrambling.
|
|
Only really useful for FPGA builds.
|
|
- snps,has-lpm-erratum: true when DWC3 was configured with LPM Erratum enabled
|
|
- snps,lpm-nyet-threshold: LPM NYET threshold
|
|
- snps,u2exit_lfps_quirk: set if we want to enable u2exit lfps quirk
|
|
- snps,u2ss_inp3_quirk: set if we enable P3 OK for U2/SS Inactive quirk
|
|
- snps,req_p1p2p3_quirk: when set, the core will always request for
|
|
P1/P2/P3 transition sequence.
|
|
|
|
This is usually a subnode to DWC3 glue to which it is connected.
